piece by piece inspection


Do you know how the piece-by-piece inspection of goods works in China? Why do we need to check each piece before shipping it to the consumer?

Due to overseas trade and online business deals, people can only see your goods’ quality once they reach the customers’ doorsteps. One slight mistake on the consumer’s end can cause them a lot of trouble.

It is crucial to have procedures that evaluate the quality of your items before they are delivered to a customer’s doorstep thousands of miles away when things are manufactured in China. Because of this, many importers decide to check the quality of their products before exporting. We are frequently contacted by importers wondering if we can perform a piece-by-piece inspection in China.

This blog will cover all you need to know about these inspections, including deciding if they are the best option for your quality control initiatives.

What is Piece-by-Piece Inspection in China?

In China, a service demands that every item be examined to assess several factors. These factors might be analyzed using the customer’s own desired specifications, or they can be general appearance, artistry, functioning, safety, etc.

The procedure of piece-by-piece inspection in China can be carried out at your location, your provider’s location, or the China warehouse handling facility.  

China uses piece-by-piece inspection to lower or completely remove faults and increase quality. Buyers that need to ensure that their products are fully compliant and meet demanding consumer and market quality requirements will find this extremely helpful.

Piece-by-piece inspection services of various companies:

When you order something from China, you should search for the best inspection service providers there to get the quality of goods checked. Many platforms in China provide you with the facility to inspect goods at competitive rates.

If the quantity of products is less, the piece-by-piece inspection can be carried out within the premises of the factory. On the other hand, if the products are more and require several days for inspection, it may be done elsewhere.  

You can also ask the company you hire for inspection to go to the site for the process. In case you are receiving goods in batches, you can deliver each batch of products to the address of the inspection company. The staff will check the goods, pack them and send them your way if everything is in good condition.

Examination of Products

Examination of products

Sort inspections are carried out piece by piece, just as 100% inspections, but their objective is to find a particular problem the service provider found during a routine inspection. Every single product component is examined, but only for one specific issue.

For instance, a company that produces t-shirts may find out during an inspection that a particular shirt is entirely the wrong shade of red, yet they must nevertheless send the jerseys to the shop as soon as possible. In order to remove the defective goods, a sort inspection is done to check for proper colouring.

After the factory has located and corrected the issue, the good items can be dispatched, and the flawed ones can either be discounted or remade.

Two Steps of Piece-by-Piece Inspection

Quality checks, which are typically conducted in two steps

  • In-process checks  
  • Post-production checks

Both of these steps are discussed in detail below.

a. In-process Checks

Inspections are carried out in-process to spot any product specification deviations and to make sure that all parts are uniform. They are typically executed when 20% of production has been completed. Such inspections assist in reducing waste and avoiding expensive delivery delays by enabling faults to be discovered and rectified early in the production process.  

However, it is preferable if these tests are not carried out too early in the production process. That is because companies typically make process adjustments after analyzing the first batch of imperfect specimens that come off the assembly line as part of their internal quality assurance checks.

b. Post-Production Checks

post production checks

Quality inspectors randomly choose components for post-production inspections and check them for issues. Additionally, they look for suggestions for changes made after the in-process assessment. It is occasionally checked to see if the packing and labelling quality corresponds to the customer’s criteria.

Benefits of Piece-by-Piece Inspection

Piece-by-piece inspection in China is very common because it brings in a lot of benefits. China is the greatest manufacturing hub in the world, and most people order goods from Chinese suppliers. When the number of manufacturers increased, and various sellers started selling similar products, it became difficult to differentiate between the quality.  

People who invest a lot of their money in international trade agreements and offshore manufacturers are always cautious about the quality of goods. The piece-by-piece inspection in China is a very smart way of getting clarity about the quality of goods. Following are a few positive points about the method that can convince you to use it.

In light of our experience, we would like to highlight three reasons why some importers prefer to do product inspections in China:

a. The cost of returning defective goods is high. It is worthwhile to invest additional time and resources in cleaning up all the damaged goods.

b. Bundle or repackage according to your needs.

c. There is a strong suspicion that the supplier’s quality control is subpar and that many of the items have quality issues.

d. Following the examination, exchanging substandard goods for standard ones is possible.

Which One is Better in China? Sampling Inspection VS Piece-by-Piece Inspection

Implementing a comprehensive inspection method is always a good idea when producing overseas and shipping from China. Intentional QC procedures can make up for the absence of direct supervision brought on by distance.

Inspections are generally necessary and appropriate. It helps you remove doubts regarding the manufacturer’s quality control procedures and believes that a significant portion of your products may be defective.

The 3-Step Checklists to Access the Quality of Goods

Before exporting, you want a chance to repair or replace damaged goods. Receiving an excessive amount of defective merchandise would be expensive or have serious impacts on your company.

There are two options for inspection, piece-by-piece inspection or sampling inspection. Sampling inspection is a strategy for choosing a part of your items to check. This method has been statistically validated, and sampling inspection is considered better in many circumstances.

a. What to choose?

There are typically two approaches to carrying out such quality check operations when purchasing items in China either piece-by-piece sampling or sampling inspection. The decision between completing a quality inspection using a sample approach or performing a 100% quality inspection is one of the most frequent dilemmas an importer or an overseas buyer may have. There are a few things to think about when choosing.

b. Quantity

Sampling inspection will be considerably more efficient in terms of time and money if you have a large number of goods. However, if you only have a small number of items, it might be more affordable to have all of your goods inspected as the cost of the two inspection methods may be equal.

c. Timeframe

Piece-by-piece inspections need more time than sampling examinations. Sampling can be the best option if you need an inspection procedure that is quicker yet still effective. Product Type:

Piece-by-piece inspection is preferable if you are producing high-value goods (like $10,000 watches) or goods with a high level of risk (like medical equipment or aeronautical components).
