Why are Inspection Services in China Vital for Manufacturing?

2022-06-07

插图1.jpgIf you're purchasing your goods from abroad, quality control and inspection are significant problems. Numerous nations were outsourcing their manufacturing to China due to the low cost and cost-effective, high-quality services. Many companies place their orders in bulk or outsource manufacturing to China.

Certain companies would place orders for products from unknown manufacturers; resulting in significant loss. Thus, the quality and the inspection services in China were essential for companies who chose to place their order to Chinese manufacturers. Therefore, a China inspection company is crucial to oversea buyers. Such inspection company will assist the buyers throughout and follow the process to meet their demands with quality.

The process of quality control in manufacturing can help companies around the globe make sure that their products are manufactured according to the standards set by the manufacturer. In China, all reputable manufacturing companies conduct in process quality inspections. However, it is highly recommended that buyers work their reviews through a third party like a China product sourcing agency specializing in these inspections. This is especially important if the product needs to comply with government-prescribed safety standards.

Implementing controls for quality and inspection can assure you that the Chinese producer or provider will meet your requirements for quality. Quality control and inspection services in China involve two steps, namely Quality Assurance (QA) and Quality Control (QC).

QA consists of establishing procedures and ensuring that the manufacturer adheres to them throughout production to meet quality standards and reduce or eliminate the possibility of defects. It also includes training, changes in control documents, China factory audits, investigations, and other actions. QC is completed after production, before the time that products are delivered. It involves batch inspection and product sampling to determine defects, validation, and laboratory testing. This method ensures that finished products meet the standards set by the manufacturer.


Quality inspections in different types

1. Pre-Production Inspection (PPI)

All raw materials and components are tested and verified by the quality inspector or third-party independent inspection companies. 

2. During Production Review (DUPRO Inspection)

Production inspection is generally completed after 50% of the products are produced. Quality inspectors first inspect the factory to find issues with the product, should there be any. Then, the units are selected randomly and then assessed against specifications for the product as determined by the customer or the relevant inspection body.

3. Pre-shipment Inspection or Final Random Inspection

FRI, also called PSI, is completed when production has been completed, and at least some percentage of products is ready for shipping. Products are checked randomly. This involves an on-site inspection to verify that the products meet your specifications and comply with the industry's requirements, country, and other specifications. This also involves ensuring that there aren't any minor or major defects within the products.

 

What are inspectors looking for in QC inspections?

Quality control inspectors verify that the item is in line with the client's specifications, which could be things including: is the color identical to the sample? Does the dimension fit the tolerance of the drawing? If not, do they fall within the acceptable deviations?

Inspectors will also ensure that all of the 100 pieces of an entire batch are in the same range of quality. Even if some aren't right, it's preferable to be sure that they are in the same proportion because this generally means that there's a system issue in the system, and it's relatively simple to correct.

Suppose the deviations vary widely, with some being amazing and some being a disaster. In that case, there is something more to it that could signify the facility's inability to establish precise production control. In these instances, it's best to determine the root of the issue, try to solve it, and possibly consider a different factory if it persists.

What happens if problems are discovered in inspections?

When there are problems, factories are directed to alter the produced product and ensure the issue doesn't recur throughout the order.

Sometimes, reworking a bad batch is costly and time-consuming, delaying delivery time. If we understand the purpose of the product, for example, and are confident that the errors will not affect its use, we could allow the batch to go but make sure to establish a process to rectify the issue for all the sets.

Think about a tap that is used inside the bathroom. It has a visible side and a side that runs to the wall or into the sink. If there's a flaw in the part destined to go into the wall or the sink, we'll clean the batch, but be sure that you report the issue to the manufacturer and notify the customer. In most cases, the customer will be satisfied that we made the right choice because the flaw doesn't affect the usage, and the final buyer will probably not notice it.

 

Things to include on your QC checklist

Before you finalize the order or before the beginning of production, you should communicate your specifications for the product to the supplier via the form of a QC checklist. It should include the specifications for the product and the quality standards that the supplier has to adhere to, and an objective set of criteria to be inspected. Here are some guidelines you should include on your checklist of QC.

  • Product specifications- Material and height, weight, and many other factors.

  • Packaging and labeling- Accurate packaging and labeling are crucial to meet the requirements of various industries. Certain products must be verified and labeled by labs that are certified.

  • Visual inspection or on-site testing and tests -This should be part of your list to inform your supplier that this will occur.

  • Defect classification -There are three defects in QC inspections: minor, central, and critical. Always submit a valid sample in the form of a product video or images for your Quality Control Inspector.

  • Testing for functionality -If you import an item, you must outline the procedures for testing the device's use or functionality.

  • Specific tests - For certain kinds of products like pharmaceuticals or chemicals, particular samples are sent to labs to assess their quality, based on the specifications of the importers.

  • Tests on the drop of a carton - This test are conducted to determine the strength and durability of the packaging before the items are shipped.

 

How do you choose a reliable China inspection Company?

1. Visit the inspection firm in person

 For certain companies that offer inspection services in China, we are betting you're not going to trust them with the task of checking your products when you have visited their offices in person for five minutes. Certain businesses are situated in homes or apartments, and many youngsters sit there. They are often gone overnight. No, whatever you're doing in China, you must schedule 2 hours to visit your quality control company to be secure. You will sleep better following a short visit.

2. Company Qualification and Accreditation

Many inspection companies boast they hold ISO9001 certification. ISO9001 is a good thing (please verify the business coverage of the document). However, it's universal for all businesses. The most crucial certification for inspection services in China, regardless of whether they are located in China or other countries CNAS17020 (equal to ISO17020 and IEC17020) in addition to AQSIQ (Chinese official government certification). If an inspection firm does not have CNAS17020 or AQSIQ accreditation, it's unlawful for them to perform inspections by a third party.

Every inspection service in China claims they provide excellent service and high-quality reliability. Maybe... However, certain inspection firms are too large to care about their smaller (or even medium-sized) customers. You'll find it challenging to get in touch with them after 6 pm late. Some are too small to have a good organization. Due to a weak network or lack of experience in the area, they must utilize a lot of part-time inspectors, which could cause lots of problems, not only for the purchasers but also for the company conducting the inspection.

4. Prices

Simple prices are nothing without these factors, including whether the inspection cost includes travel expenses and the size of the sample per day for each man, and the inspectors' qualifications and background.

If you disagree with the current inspection estimate, you may request a time breakdown and more specifics. It is possible to calculate the time it takes to do a single-piece test and then determine if it's fair or not.

 

Conclusion

Importing can be profitable. But to maximize profits, it is essential to ensure that you don't make a mistake due to minor quality issues. Although it's impossible to examine the product and verify its quality while away or on the internet, third-party companies can provide these services.

If you are looking for a business to provide quality inspection and control, then look for a reliable inspection services in China that can keep you informed about your product throughout the course.
