Pre-shipment inspection in China: what it is and why it matters

A pre-shipment inspection (PSI) is a check of your goods before they leave the factory. An inspector verifies quality, quantity, packaging and labels against your order and your specifications, so you find problems while the goods are still in China and the supplier can still fix them.

If you skip it, you risk customs delays and higher costs, fines for breaking rules, customer complaints from bad products, financial losses from returns or recalls and damage to relationships with partners.

In short

• Pre-shipment inspections stop expensive errors by checking quality early.
• They lower risks like customs delays, fines and complaints.
• A report (and certificate, where applicable) shows your goods meet your requirements and makes buyers trust you more.
• A trusted inspection service makes communication with suppliers easier.

What it is and who needs it

The main purpose is early detection: finding defects and rule problems before shipping, which saves the cost of returns, repairs and recalls, makes customers happier and reduces the chance of breaking standards.

Whether it's legally required depends on the product and the destination country: some countries and industries require inspections or certificates for certain goods, and your contract may require one too. Even when it isn't required, it's a sensible step for most buyers. It's used on all kinds of goods: softlines (clothing, textiles, shoes), electronics and electrical items, hardlines (tools, hardware, home goods), industrial equipment, plus related services like factory assessment and loading supervision.

The process

1. Planning and scheduling. Check that production is around 80% complete (and packed) so most items can be inspected, count the goods against your order and agree a date. Good planning avoids delays.

2. Sampling. Inspectors use random samples based on AQL (Acceptable Quality Limit), following ISO 2859-1. They pull items from packed cartons, and how many depends on the lot size. They look for defects, check dimensions and test that products work and are safe.

3. Packaging and labeling. They check materials, barcodes, safety marks, manuals and legal labels, and any certifications you need, such as CE, FCC or RoHS. That helps you avoid customs trouble.

4. Report and follow-up. You receive a report on quality, quantity, packaging and labels, usually with photos and test results, and you may also get related documents such as the order, packing list, invoice, bill of lading and certificate of origin. If there are problems, you ask the supplier to fix them before shipping. Feedback also builds a better relationship.

Why it matters

• Quality and compliance: finds defects, confirms the goods match your order and meet quality and legal rules.
• Risk and cost: with a report you can accept or reject a shipment, saving money on returns and unhappy buyers. Regular checks also keep suppliers' quality up.
• Customer satisfaction: your customers get what they expect and your brand stays strong.
• Smooth supply chain: checking quantities helps shipping and inventory.
