Product Inspection in China

In the current highly globalized world, it is next to impossible to talk about manufacturing without mentioning China. The supply chain of most import-export businesses globally has at least one supplier in China. While sourcing manufactured goods from China offers a wide range of benefits, it also comes with a myriad of challenges.


According to global product inspection data, AQL failure rates for China is around 30%, which means that one-third of the products are either defective or non-compliant with custom regulations. But, you can avoid quality issues and mitigate the risks of non-compliance by adhering to QC best practices. Whether you’re a retailer or an importer, quality control in China is important.

What is Quality Control in China?

China’s quality control refers to proactive measures taken by importers and their inspection agencies in China to guarantee product quality. To ensure you import quality products, China’s quality control process is designed to help you partner with the right supplier. Audits focusing on verifying potential suppliers can avoid scammers and incompetent manufacturers while factory audits can highlight the capabilities of suppliers. Social audits assess the supplier’s ethical conduct like equality in the workplace, environmental issues, and human rights. The audits and inspections used in pre-production lay the foundation of the China QC process but it should be guided by a comprehensive quality control checklist.

Once you find and partner with the right supplier or manufacturer in China, your inspection agency will focus on product inspection starting with an initial production check before mass-production then proceed to DUPRO and PSI. Your quality control process in China is completed when the inspection agency supervises the loading of your products for shipping. It is undeniable that adhering to quality control best practices when dealing with suppliers from China offers a wide range of benefits.

Who can Undertake Quality Control for Imports from China?

Quality control goes beyond the jurisdiction of one entity. Importers engaged with suppliers from China can delegate their quality control process to one of four entities:

In-house Manufacturer review. Importers award the manufacturer the authority to oversee quality control. It is risky since they will be reporting on their operations.

Buyer QC. As the buyer, you can undertake quality control by visiting the manufacturer yourself or appointing one of your staff members to oversee the entire process.

Supplier or Sourcing Partner. You can assign quality control to your partner or supplier in China, which is also risky.

In-house Inspection Team. Hiring or creating a QC team within your company is also a perfect option to ensure accurate and unbiased results. It can be costly and unprofessional.

Third-Party Inspection Agency. You should hire a third-party inspection agency like Tetra-Inspection with years of experience in the Chinese manufacturing

  • Product requirementsPackaging specification like
  • packaging materials and packing method

  • On-site Product Tests
  • Labeling and marking like CC Mark of Quality

Inspection and audit types in China Quality Control Process

To ensure your product meets the requirements and specifications, the inspection agency will conduct a step-by-step assessment known as the China quality control process. The process consists of several types of product inspection and supplier audits.


Quality control audits can help you partner with the right supplier in China and avoid the risk of non-compliance and quality issues. Here are the four most common types of audits in China:

This audit is conducted when searching for the right supplier in China. It is used to verify the authenticity of a potential supplier and can help you avoid scammers masquerading as Chinese suppliers.

This audit focuses on social practices in the workplace of potential suppliers and can dig up any unethical social practices like exploitative labor. It can help you avoid unethical suppliers in China and protect your reputation.

This audit focuses on the capability and capacity of a potential supplier. It ensures you partner with a supplier capable of delivering your requirements.

An example of specific audits is Amazon FBA, which helps Amazon sellers get the right supplier in China.

Whether you are a retailer or importer, these audits can mitigate risks and help you partner with the right supplier. You can enjoy all these benefits by hiring an experienced third-party inspection company like Tetra Inspection to audit potential suppliers for you in China.

Initial Production Check includes several on-site inspections by third-party inspectors to assess your manufacturer’s production capacity, materials, and the implementation of the requirements. The inspections start before production begins to ensure the supplier can deliver an acceptable quality limit (AQL). It can last until 20% of production has been completed for First Article Inspection. The first items off the production line are inspected to correct any defects before mass production.

DUPRO, also known as On-Line Inspection, is an on-site product inspection in China conducted in the early stages of production when about 20% of the batch has been produced. It is undertaken to track quality and production progress. Importers engaging with suppliers from China can hire a QC expert to conduct DUPRO in the supplier’s factory to surface any defects before too many items are produced. DUPRO in China can help you reduce costly defects and quality issues in the early stages of the manufacturing process.

Pre-Shipment Inspection (PSI) is a systematic inspection of a sample selected randomly from all the batches already produced. It is conducted based on ISO standard sampling procedures to detect and solve any quality or conformity issues before the shipment. PSI is carried out near the end of production when at least 80% of the units in the order have been produced and ready for delivery.

Container Loading Check (CLC) is the final step in product inspection for imports from China and focuses on ensuring that only approved products are shipped. Your third-party QC inspector will check the accuracy of the total quantity and the number of products loaded in regards to sizes, color, and styles in shipments. The number of products loaded for shipments heading to different destination markets is checked. Any issues with the quantity loaded are addressed before shipment is delivered to you.
