If you are sourcing products from China, quality inspection is one of the most important steps to protect your business. Whether you run an Amazon store, a Shopify brand, or wholesale distribution, a reliable China quality inspection service ensures that your products meet your specifications before they leave the factory.

In this guide, we’ll explain everything you need to know about quality inspection in China, including types of inspection, the standard process, costs, and how to choose the right partner.

🟦 What Is Quality Inspection in China?

A quality inspection is a process where a trained inspector examines your goods before, during, or after production to ensure they meet:

• Your product specifications

• Quality standards

• Regulatory requirements

• Packaging requirements

• Functional and safety requirements

Quality inspections help you discover issues early, avoid defective products, and prevent returns or customer complaints.

🟦 Why Quality Inspection in China Is Essential for U.S. Buyers

Here are the most common risks when sourcing from China:

• Factories changing materials without informing you

• Inconsistent production between batches

• Quality drop when factory is overloaded

• Miscommunication about specifications

• Wrong labeling or packaging

• Safety risks for electronics, toys, and cosmetics

A proper inspection eliminates these risks and ensures your goods are ready for shipment.

🟪 Types of Quality Inspection in China

Below are the four most common inspection types used by international buyers:

1. Pre-Production Inspection (PPI)

Used when you need to:

• Verify raw materials

• Confirm factory understands your spec

• Avoid wrong components

• Ensure the production plan is realistic

This step prevents mistakes before they even happen.

2. During Production Inspection (DPI)

Recommended for large orders. Inspectors check:

• Production progress

• Semi-finished goods

• Processes & workmanship

• Risks that may delay shipping

It allows you to correct issues while the goods are still in production.

3. Pre-Shipment Inspection (PSI) (Most Common)

Conducted when 80–100% of the order is completed.

Checklist usually includes:

• Quantity verification

• Workmanship check

• Function test

• Packaging and labeling

• Drop test

• AQL sampling (International standard)

Most U.S. importers rely heavily on PSI.

4. Container Loading Check (CLC)

Ensures:

• Correct quantity loaded

• Proper packaging & sealing

• No product swap

• No damage during loading

Useful for high-value electronics or fragile goods.

🟧 What Is AQL in China Quality Inspection?

AQL = Acceptable Quality Limit
It is the global standard used to determine pass/fail for inspections.

Common AQL levels for consumer goods:

• AQL 2.5 – Major defects

• AQL 4.0 – Minor defects

If defects exceed the allowed number, the batch fails, and the factory must rework.

🟩 How Much Does a China Quality Inspection Cost?

Typical pricing in China:

• $120 – $300 per man-day
  Depending on location, schedule, and product type.

Additional fees may apply for remote areas or urgent inspection.

🟦 Quality Inspection Process (Step by Step)

Here’s how a standard inspection works:

1. You submit product specification + PO

2. Inspector visits factory

3. Inspect samples using AQL

4. Take photos, videos, function tests

5. Draft detailed inspection report

6. You decide pass / fail

7. Factory rework if necessary

A reliable inspection partner ensures transparency and prevents disputes.

🟪 Common Issues Found in China Inspections

During inspections, the most frequent problems include:

• Scratches, dents, or dirt

• Incorrect dimensions

• Missing accessories

• Weak welding or bad stitching

• Wrong barcode or label

• Shortages in quantity

• Poor packaging protection

These issues are much easier to fix before shipping.
