Product quality control is key to ensuring 100% functionality of your end product, which translates into a high user acceptance rate. Earlier, enterprises had a dedicated quality assurance testing team that was tasked to conduct rigorous product quality tests as per the enterprise’s specifications.

Cut to the present day, things have changed in the quality management arena. Companies have deepened their focus on the end-user perspective than their vision regarding a product. This change is witnessed in things like software development, the performance of a medical device, analytical services and others.

There are no two thoughts about the fact that the perspectives of end-users are extremely dynamic. Enterprises need to introduce multiple ad-hoc changes during the entire product development lifecycle to align with the dynamic user perspectives. This has created extreme pressure on the in-house quality control testing experts.

In-house quality management experts lack the bandwidth or expertise to look beyond the conventional total quality management framework and work out a flexible quality testing solution right off the bat.

This compelled enterprises to form a beeline for quality outsourcing to reap the actual benefits of quality control. According to a Forbes Technology Council Post, the software quality system outsourcing market which was valued at USD 40 billion in 2019 is set to grow at 6% through 2026.

On this note, here’s looking at the top 5 reasons why outsourcing product quality control can prove to be the turning point for your business.

1. Outsourcing Product Quality Control for Cost Optimization

As stated earlier, enterprises require the best minds and tech stack at work to align with the fast-changing quality assurance testing standards. For instance, post-pandemic, supplier quality compliance requires the introduction of highly sophisticated cloud-based digital tools.

Highly talented quality management professionals are short in supply and can be quite expensive to hire. Procuring new infrastructure is also a costly proposition, particularly for an individual entrepreneur with no guarantee of the best ROI. In the current high-risk and fast-paced marketplace, no enterprise of any size can afford to lose money or time.

Since quality control procedures are the core function of QC outsourcing service providers, companies ensure that they house the cream of quality testing analysts and infrastructure to stay at the top of the game. Partnering with such a service provider allows enterprises access to such talents and infrastructure at half the quality control cost of procuring them in-house.

Most QC outsourcing service providers are known to offer flexible pricing. This means that an enterprise can pay only for the quality management service they have used at a certain time. It enables huge product quality control cost savings for enterprises as opposed to paying a fixed monthly compensation and other monetary benefits to the in-house team despite a low work volume.

2. QC Outsourcing for Access to Talents on a Global Level

The Covid-19 pandemic-induced mobility restrictions and lockdowns created a severe resource crunch during critical quality assurance phases such as software testing, manufacturing process quality compliance and many more.

Enterprises heavily relying on their local in-house quality testing team do not have a backup in case of emergencies such as political unrest or a pandemic. Such situations deter teams from commuting to their workplace and provide remote support with limited infrastructure. This either halts the entire quality management process or compromises the entire quality compliance test standards.

Prominent outsourcing quality control firms have resources spread across the globe with local quality assurance managers inspecting a team. Such firms have the bandwidth to ensure resource availability from regions that escape the impacts of a pandemic or any socio-political unrest. This exempts enterprises from the pain of managing an in-house quality testing team in affected regions. QC outsourcing firms assign dedicated supervisors who are adept with the region’s vernacular and regulatory requirements and hence are best suited to manage the quality management team.

3. Product Quality Control Outsourcing Brings in Expert Knowledge

Quality control outsourcing firms are home to testing experts who have exceptional domain knowledge. They tap into this knowledge to think beyond the traditional quality management framework to bring product and process improvements beyond a short span of time.

They stay at the top of the testing standard dynamics and all the regulatory requirements pertaining to it. Such experts make a continuous effort to hone their testing skills with the newest technologies disrupting the market. This is particularly pertinent in the software testing genre, where enterprises face the constant pressure of launching products at lightning speed and are bugs free.

With hands-on experience with the newest product quality compliance tech, outsourced software testing experts require minimal to no handholding during the software development lifecycle. They liaise with developers and designers, understand the objective of the product and test the same from the user’s perspective.

4. Quality Outsourcing to Address Integrity Risks

Quality assurance integrity risks are rampant across many industries. Such risks include bribing quality assurance personnel with money, gifts, or other subtle forms of bribery such as personal transportation provided for an onsite inspection, taking out to lunch and other such instances. These integrity risks, if not addressed beforehand, resulting in the leaking of confidential information, biased quality inspection, or counterfeiting of products.

It is not always possible for an enterprise to keep a check on the auditory activities of its in-house quality testing team. Such a lack of control creates cracks through which integrity risks may slip in.

Partnering with experienced quality testing service providers will help address these integrity risks to a significant extent. They conduct frequent inspections of the auditing activities of individual quality testers. Third-party quality control firms enforce stringent compliance guidelines that forbid quality testers from accepting favours of any kind.

They leverage digital audit software that creates a trail of all quality assurance activities. This trail is critical to flag any incident that does not comply with an enterprise’s pre-set quality compliance standards. Third-party quality control firms are known to implement and religiously follow QA process maps. These maps help the third-party service providers bind all the quality testing experts to a set process, deviating from which issues warnings to the team supervisor.

Additionally, third-party quality control firms implement incentive programs, sudden quality control checklists and tracking inspection activities, to keep any integrity risks at bay.

5. Outsourcing Quality Control for Better Business Flexibility

One of the biggest benefits of QA process outsourcing is the flexibility that can be the real turning point in an enterprise’s business. A client does not need to be bound by a service contract. Such a binding service contract compels the client to pay service fees for a certain point irrespective of the volume of work. It also compels the client to work with the limited resources they have for quality management.

Contrary to the above, third-party quality control service providers cater to quality assurance as and when needed. The service providers station resources across various time zones. This allows them the liberty to respond to their client’s quality testing needs anytime and anywhere.

The client gets to pick and choose a team of experts without having to go through the hassles of hiring and training resources. This allows ample business flexibility for a client who can work with a team of the best of experts round the clock on a need basis.

Conclusion

Quality management has pivoted from being conducted from an enterprise’s vision to the end user perspective. This makes outsourcing even more pertinent as this helps to bring a fresh perspective to the QA process. An in-house tester is bound to think in a linear way. It is mostly because they work towards a set direction in liaison with the developers, designers and business analysts. Third-party experts bring in industry insights and a fresh objective. It manifests into an unbiased quality assurance which is a big turning point for an enterprise’s business in the competitive marketplace.

If you run, own or manage a business, you know how vital selling quality products is to business success. You want your customers to get products that meet or exceed their expectations and satisfy their needs. Here’s where quality inspection comes in.

What is quality inspection?

Simply put, quality inspection is a procedure or set of procedures that involve checking the various characteristics of a product and testing it to ensure it meets pre-specified standards. Usually, a product is examined and measured, and the results are compared with the specified requirements to establish whether conformity is achieved for every attribute.

During the process, an inspector keenly follows a pre-established checklist based on the specifications of a particular product. Quality inspection can be performed on semi-finished goods, the components used for production and finished goods before shipment to the consumer.

It’s advisable to outsource quality inspection to a third-party inspection company to save time, money and effort. Besides, by outsourcing, you get expert services from a company that specializes in product inspection.

Types of quality inspection

Generally, all quality inspection services can’t be adapted to the same situation, but the four common types of quality inspection include:

1. Pre-production inspection (PPI)

PPI helps to assess the quality and quantity of the raw materials and components and if they conform to pre-specified product specifications. It’s conducted before the production process starts and is beneficial to the businesses that work with various suppliers, want a new supplier, or have a large project with critical delivery dates.

It aims to eliminate mistrust between you and the supplier, ensuring no one cuts corners.

2. During production inspection (DUPRO)

DUPRO is vital in the manufacturing process as it gives you an idea of the product quality early in the production cycle. This way, you’re able to take corrective measures and re-work products before continuing with production.

Normally, DUPRO is conducted when a few finished products come out of the line.

3. Pre-shipment inspection (PSI)

Pre-shipment inspection checks the quality of products before they’re shipped to ensure production complies with the set product specifications. It’s usually carried out when 80% of the products are packed for shipping by selecting random samples for inspection.

4. Container loading inspections

Container loading inspections are rarely used, but they can be a worthwhile option in some instances. For example, if you have packaging that’s not conventional or is fragile, container loading inspections come in handy to ensure your loading plan is respected and followed.

An inspector supervises the entire loading and unloading process, ensuring your products are handled with professionalism and care to guarantee safe arrival.

Quality inspection for your business

Most businesses use one or two of the mentioned quality inspection types, but you may need all four if you’re managing a sensitive project. However, it’s essential to note that an inspector might choose different approaches depending on the specs of your product and your industry.

It’s vital to work with an experienced product inspection company like GIM for a smooth and seamless quality inspection process. Contact us today for all your inspection needs.

Quality control charts also called the Shewhart chart are used as an important part of process improvement techniques in numerous industries. Variations within any process are an unavoidable aspect. But when timely corrective action is not taken then these variations can affect the business negatively. The importance of quality control charts is, in such scenarios, to study the changes happening over time in the process.

Control charts are graphs with a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. Control charts in quality control are used as a tool for data collection, data comparison and analysis. For variable data, these charts are used in pairs whereas for attribute data they are used singly.

What is a control chart in quality control?

In quality control, control charts are always used in combination with other process improvement tools. Across industries such as healthcare, service, manufacturing or others, control charts can be used to monitor how variables change over time. Using quality control charts effectively is all about having a good understanding of the variations and enabling continuous improvement.

A control chart in quality control is especially useful to monitor the process that is under statistical control. Quality control charts are considered one of the seven basic quality tools for process improvement and are used in Lean Six Sigma projects and DMAIC (an acronym for Define, Measure, Analyze, Improve and Control) projects that are under the control phase.

The importance of quality control charts is to enable the visualization of variation, monitor for problems and take actions to improve processes, predict expected outcomes and also to analyze the variation patterns. For optimum quality control, it is crucial to identify the right control charts on the basis of the available data.

Importance of quality control charts

Quality control charts are one of many graphical tools used in quality control analysis to understand the process changes that occur over time. The importance of quality control charts is evident in their use as statistical quality control tools. Statistical control charts are used to determine variables, ascertain unit defect fractions, find out the faults per unit and also as a procedure for acceptance sampling. It is not feasible for the manufacturer to inspect the entire batch of products for quality control, and this makes sampling necessary.

Here are some benefits of control charts that aid in quality control:

• Determine process variations that occur within and outside of your control limits.
• Find problem indicators, and know beforehand if something may or may not go wrong in the process.
• Determine patterns within plotted points that could be the possible causes of variations.
• Guide in deciding the right solutions or corrective actions to be taken.
• Forecasting future performance.
• Find new ideas to improve quality on the basis of analysis from quality control charts.

Types of quality control charts 

There are different types of quality control charts and each of these was developed to suit particular characteristics of the quality attribute being analyzed. These differences among the charts are depending on whether the nature of the monitored data is variable or attribute.

P chart in quality control

P charts in quality control are used when the data to be monitored is counted and when the sample size can change over time. Each of these data points is a ratio of its own discrete sample set. P charts can show the fraction or percentage of nonconforming data values and if this proportion changes during the sampling period.

NP chart in quality control

NP chart in quality control is similar to the P chart. The difference is that the sample size will need to stay constant during the sampling period. These charts are the best when it comes to presenting the number of non-conforming or conforming items. In this chart, the number rather than the fraction of non-conformances is recorded.

C chart in quality control

C chart in quality control is used to monitor and control data that is in the form of specific numbers.This can include data such as the number of defects in a batch of raw material inspection or the number of defects in finished products. C charts are best suited when the number of defects per sample unit and the number of samples per sampling period remains constant. C charts show non-conforming or conforming items within a consistent unit size and in a specific period of time.

S chart in quality control

The S chart in quality control is also called the Standard Deviation chart. This control chart is used for monitoring data that is variable and when large numbers of samples need to be recorded. By using the standard deviation all data within a sample set are utilized to determine the variation and not just the minimum and maximum values.

X chart in quality control

The X chart in quality control is used to monitor the statistical mean or average of a variable in a set of samples. These charts can then be utilized to find the actual process mean, versus a nominal process mean. The X chart shows variable data and also if the mean output of the process undergoes any change over time.

Quality control is an indispensable part of any manufacturing process to ensure that products meet the required standards before reaching the consumer. Manufacturers rely on various quality control methods, including the Acceptable Quality Limit (AQL) sampling, to achieve this goal. AQL sampling is a statistical method that enables manufacturers to determine whether a batch of products meets the required quality level. In this blog post, we will provide a comprehensive guide on the AQL sampling table, a vital tool in the quality control process.

Before we delve into AQL, let’s understand what is AQL. The Acceptable Quality Level (AQL) refers to the maximum allowable defect rate that is considered tolerable, as established in ISO 2859-1. The AQL provides the limit on the acceptable number of defective components in random sampling quality inspections. Typically, it is expressed as a ratio or percentage, representing the number of defects relative to the total quantity.

What is AQL Sampling Table?

An AQL sampling table is a chart that contains different sampling plans based on the AQL level, lot size, and sample size. It is a tool that helps you decide whether to accept or reject a batch of products based on the number of defects found during the inspection.

Any industry that produces goods or products that need to meet specific quality standards can benefit from the use of AQL sampling tables. By ensuring defects are caught early in manufacturing, companies can improve quality, reduce costs, and maintain a positive reputation with customers. The industries that use AQL tables include, but are not limited to:

• Automotive: The automotive industry is one of the sectors that rely heavily on AQL sampling tables. This is because the industry greatly prioritises quality and safety standards, and any defects can lead to disastrous consequences.
• Manufacturing: Manufacturing companies use AQL sampling tables to ensure their products meet quality standards. Manufacturers can identify defects and adjust their production processes to improve quality by inspecting random samples of finished goods.
• Textiles and apparel: In the textile and apparel industry, AQL sampling tables are commonly used for garments inspection such as holes, stains, or loose threads. This is particularly important in the fashion industry, where high-quality garments are essential to help maintain the brand’s reputation and customer loyalty.
• Electronics: Electronics manufacturers rely heavily on AQL sampling tables to ensure their products meet safety standards and work as intended. This is especially important in the aerospace and medical devices industries, where even small defects can have serious consequences.
• Food and beverages: AQL sampling tables are used in the food and beverage quality control to ensure that products meet safety and quality standards. By inspecting random samples of food products, manufacturers can identify contaminants and ensure that the product is safe for consumption.
• Pharmaceuticals: In the pharmaceutical industry, AQL sampling tables ensure that medications are safe and effective. By testing random samples of finished products, manufacturers can identify any defects or inconsistencies in the manufacturing process and take corrective action swiftly.

AQL Methods

There are three types of AQL methods: single, double, and multiple.

Single Sampling Plan: When a lot size is small and the inspection is less critical, a single sampling plan is used. This method involves taking a single sample and inspecting it for defects. The lot is considered acceptable if the number of defects found in the sample is equal to or less than the Acceptable Quality Limit (AQL). However, the lot is rejected if the number of defects found exceeds the AQL.

Double Sampling Plan: The double sampling plan is often utilised when dealing with larger lot sizes or more critical inspections. This method involves taking two samples, with the first sample being inspected. The lot is accepted if the number of defects found in the first sample is less than or equal to the specified AQL. However, a second sample is taken if the number of defects exceeds the AQL. Following the second inspection, the lot is accepted if the total number of defects across both samples is less than or equal to the AQL. If not, the lot is rejected.

Multiple Sampling Plan: In situations where the inspection of a large lot is critical, multiple sampling plans are the preferred method. With this approach, three samples are taken, and if the number of defects found in the samples is within the AQL limits, the lot is deemed acceptable. However, if the number of defects exceeds the AQL, additional samples are taken, and the process is repeated until a conclusive decision can be made. This method ensures that the inspection process is comprehensive and that any defects are accurately identified and remedied. By utilising multiple samples, manufacturers can make informed decisions about the quality of their products and take the necessary corrective actions to maintain the highest level of quality control.

How to Read AQL Table?

The AQL table is typically presented as a quality control chart specifying the acceptable and non-acceptable levels of defects for a given sample size and level. The table provides information on the number of samples to be taken, the maximum number of defects allowed, and the corresponding AQL level. Here are the steps to read an AQL table:

• Identify the AQL level: Determine the maximum allowable percentage of acceptable defective products. Selecting an appropriate AQL level is crucial based on the product’s importance and the risks associated with defects.
• Identify the lot size: The lot size refers to the number of products in the batch. Choosing a representative lot size for the entire production run is essential.
• Identify the sample size: The sample size is the number of products selected for inspection. This should be chosen based on the lot size and AQL level.
• Determine Accept or Reject Criteria: After identifying the AQL level, lot size, and sample size, determine the acceptable number of defects in the sample. The lot is accepted if the number of defects found in the sample is equal to or less than the acceptable number of defects. On the other hand, if the number of defects exceeds the acceptable number, the lot is rejected.

How to Determine Defects Using AQL Sampling Table?

To determine whether a batch of products meets the specified quality standard using the AQL sampling table, follow these steps:

1. Determine the sample size and AQL level based on the batch size and necessary confidence level.

2. Draw the specified number of samples from the batch based on the sample size determined in step 1.

3. Inspect each unit in the sample and record the number of defects.

4. Determine whether the number of defects in the sample is within the acceptable limit specified in the AQL table.

5. The batch is accepted if the defects are within the allowable limit. The batch is rejected if the number of defects exceeds the permissible limit.

AQL sampling table is an essential tool for ensuring the quality of products. By using this statistical sampling method, businesses can identify the acceptable and non-acceptable levels of defects in a batch of products and make informed decisions about whether to accept or reject the batch. Following the correct method and reading the table properly ensures accurate and reliable results.

Pre-shipment inspection (PSI) is a quality inspection that is done when the products are 80% packed, 100% completed and ready to be shipped to the customers. This quality control procedure is usually done onsite at the manufacturer’s premises. It is a mandatory checking done to ensure that only quality products are shipped, thereby helping importers, traders, wholesalers and customers as well.

In this pre-shipment inspection process, trained inspectors select random samples of the products using universally accepted statistical sampling methods. During inspection, the quality, quantity and volumetric size of the finished goods are ascertained. Pre-shipment inspection agencies are certified as per the Agreement on Pre-Shipment Inspection, introduced by the World Trade Organization in 1994.

Why Is PSI Needed?

With the demand for consumer products rising, developed countries began looking to manufacturers or suppliers in developing countries. Pre-shipment inspection services became an integral part of quality control. In order to ensure that substandard products don’t reach the customers, rigorous quality checks have to be done during shipment inspections. 

The need for pre-shipment inspection is to always be in compliance with international regulations and government guidelines. This also helps to steer clear of legal issues arising from poor quality control measures. Defective products can lead to reputational damage as well as financial losses for the manufacturer.

Doing such timely inspections allows manufacturers to have information with regard to the quality of the products at an early stage. This is especially useful if reworks need to be ordered and overall product standards are to be maintained. Here are some other advantages of conducting such inspections:

• To inspect packing, shipment marks and labelling
• To determine the percentage of defects in the shipment order
• To ensure proper product functioning
• To save time, money and resources in the case of product recalls

What is the Main Purpose of PSI Inspections?

Pre-shipment inspections take place at the latter stage of manufacturing once the production run is at least 80% complete. The main purpose of a pre-shipment inspection is to reduce the risk of poor-quality products entering the market. It gives you the opportunity to catch any last-minute problems that occur, and take action to fix the issue before the product is shipped to your customers. Such inspections make the quality assessment of goods during production easier so modifications can be done in a timely manner. Once the inspection is done, the manufacturers or exporters get a pre-shipment inspection certificate that is mandatory for customs clearance in many countries.

Conducting a detailed pre-shipment inspection procedure is helpful to assess both the quality and the quantity aspect of the merchandise before it is shipped. It is also necessary to ensure that the safety guidelines are all adhered to during the quality checks. Inspections before shipping for export or import are a smart move on the part of the suppliers and manufacturers to ensure that quality standards are maintained and that even the smallest of product issues are never overlooked.

Steps in a Pre-shipment Inspection

Whether the pre-shipment inspection is handled by your in-house team of quality inspectors or if you decide to hire a third-party inspection company; here is what to expect during the whole process:

Step 1 – The inspector travels to the factory where the goods are made. The date and time for this are decided upon mutually so the products are kept ready for inspection.

Step 2 – Samples are pulled out from the product batches for conducting tests. Statistical sampling procedures like the AQL Sampling methods are followed to determine the number of pieces to be inspected in each batch. The inspection of the products is done on the basis of a pre-shipment inspection checklist.

Step 3 – Some products may require special tests like electronic items that require functional tests.

Step 4 – In this step, the packaging and the labeling are checked by the inspector. Perfectly manufactured products can also get damaged if the packaging is not sufficient or properly done. Wrong labeling can also lead to expensive delays, leading to escalations and issues with the authorities.

Step 5 – The selected product samples undergo a visual inspection for workmanship-related defects like screws missing, chipped paint or sharp edges. These defects are classified as minor, major or critical.

Step 6 – The inspector ensures that the product meets all physical requirements like height, weight, length and other criteria.

Step 7 – Verification of the barcode to ensure that it has the quality to withstand international shipping and handling difficulties.

Step 8 – This step includes testing the strength of the packaging with internationally accepted carton drop test protocols such as ISTA 1A.

Step 9 – Once the pre-shipment inspection is completed, a final inspection report is issued with the findings in detail. A shipment results in a pass, fail or hold status is given to the products or consignment.

Benefits of Pre-Shipment Inspection

Being able to determine the quality of the products in the production stage itself can be very helpful for exporters, suppliers or manufacturers. Pre-shipment inspection services are a cost-effective way to check for defects or quality issues before the shipping is initiated.

The manufacturers often determine the final date when the products can be ready for shipment by considering the time allocated for pre-shipment inspection. The pre-shipment inspection certificate received following the inspections is displayed as a part of the quality systems followed by the company.

Here are some more benefits of pre-shipment inspection:

• To check if the quantity or the metrics of products is as specified
• To minimize delivery delays and defective products
• To ensure that product safety requirements are met
• Offers peace of mind that comes from knowing product orders are completed successfully
• Ensures that you are reducing the risk of your products being returned
• Improves customer retention, delivering good quality products
• Increases your company’s ROI in the longer run

Three Methods of Pre-shipment Inspection

The three methods of pre-shipment inspection are consignment-wise inspection, in-process quality control and self-certification. Let’s look at what is involved in each of these methods:

Consignment-wise inspection

In this method, a detailed inspection is conducted on the actual export consignment that has been packed for shipment. The inspection is done as per statistical sampling methods. Once the quality check is passed, a pre-shipment inspection certificate is issued with details like the validity period during which the export should be done.

Without this certificate, no consignment of the specified commodity is given the go-ahead for export. This inspection method is especially beneficial for small manufacturers who can’t afford their own personnel or facility for the inspection of products.

In-process quality control –

This method of pre-shipment inspection is used in the case of products like paints and allied products, linoleum, ceramics, printing ink, sanitary wares etc. If such continuous process industries can prove that they have the infrastructure to manufacture or process standard-quality products, they can be approved as export-worthy production units. Such companies can do their own inspection and submit a declaration on the basis of the inspection done and following which a certificate is issued.

Self-certification –

• A self-certification system was recently introduced under the Quality Control and Pre-Shipment Inspection Scheme in India. As per this system, the manufacturing unit with the in-house provision for ensuring quality control through thorough inspections can certify their own product for export.

Types of Pre-shipment Inspection

The two different types of pre-shipment inspection are government-required pre-shipment inspection and the importer voluntary pre-shipment inspection. The first type is the inspection that is made mandatory for imported products by the government. In this pre-shipment inspection, a designated agency is tasked with inspecting the products before being shipped from the exporting country. The purpose of this type of pre-shipment inspection is to prevent the evasion of import duties, capital outflows and low-quality product imports.

The second type is when the pre-shipment inspection is not made mandatory but the importers themselves initiate quality checks before the shipment is done to protect the rights of buyers. This type of inspection majorly focuses on ensuring that the quality, quantity and specifications of the product are in line with the purchase agreement. But this inspection need not necessarily be as per ISO standards.

How Pre-shipment Services are Must for Your Business?

Ensuring that product quality meets accepted standards and customer expectations is a challenge faced by all manufacturers, importers and exporters. Pre-shipment inspection is the most effective way to minimize any issues arising from quality-related issues. Such shipment inspection also encourages production units to take preventative actions like purchasing only the best raw materials so this is reflected in the quality of the finished goods.

Pre-shipment inspection takes place before the product is completed and then packaged. It is the last stage of the process before recalls and corrections start to become very expensive, and it helps you stay away from import risks. A business that consistently produces quality products has a good reputation in the market. In the same way, continuously churning out defective products can lead to huge money-wise losses and wastage for the business. Hence pre-shipment inspections are a must and not something that should be overlooked by any means, however established the business may be.

Outsourcing Pre-shipment Inspections

Outsourcing pre-shipment inspection processes to a reputable and dependable pre-shipment inspection company in the quality control space can be a very beneficial option for your company. Here are some top reasons:

• Better communication to help minimize the language gap between you and your supplier so there is no deviation from the required standards and specifications in manufacturing your products.
• Professional inspection companies have integrity and follow strict policies so there is never any bias that could influence inspection outcomes or reports.
• They can be flexible if your company requires an inspection report in a specific format or if the inspectors have to employ specific types of testing procedures.
• The top advantage of hiring a third-party inspection company is its cost-effectiveness. This can also save you time, resources and extra effort.
• They have the resources for ensuring quick turnaround times.
• Strict compliance with ISO standards is a guarantee.
• Cutting-edge and secure inspection practices that ensure your products or commodities are always safe.
• Most third-party inspection companies offer 24-hour customer service by phone, email, and web chat as well as worldwide shipping options.
