An inspection is not a formality you buy to feel safer. It is the last point at which a problem costs the factory money instead of costing you money. Booked at the right moment and scoped properly, it is the cheapest insurance in the whole import process. Here is what a proper China inspection covers, and what buyers usually leave out.
Choose the right inspection type
Buyers default to pre-shipment because it is the one they have heard of. Often it is the wrong choice.
- First-article inspection: the first units off the line, before the run continues. Best when the product is new or customised.
- During-production inspection: at roughly 20-50% completion, while mistakes can still be fixed cheaply.
- Pre-shipment inspection: at 100% produced and at least 80% packed. The standard final check.
- Container loading check: confirms the right cartons, quantities and load condition actually go into the box.
Agree the standard before production, not after
An inspector can only report against a written standard. If you have not defined what counts as a defect, you will get an argument instead of a decision. Send the factory an approved golden sample, a specification sheet with tolerances, the packaging and label artwork, and the AQL level you expect. Keep a signed copy.
AQL sampling in plain language
AQL (Acceptable Quality Limit) defines how many random units are checked and how many faults are allowed before the batch fails. The common commercial setting is AQL 2.5 for major defects and 4.0 for minor ones, with zero tolerance for critical safety defects. The sample size comes from the batch size, not a fixed percentage — a 5,000 piece order typically means around 200 units checked, which is why a 'we checked a few pieces' report is meaningless.
What a complete report contains
If your report does not have these things, you cannot use it to hold anyone accountable.
- Quantity verification against the packing list, carton by carton
- Workmanship findings split into critical, major and minor, with photographs
- Function tests relevant to the product — electrical safety, load, zip cycles, water resistance
- Measurement check against the specification, with the actual figures recorded
- Barcode, label, manual and retail packaging verification for your destination market
- Drop test or transit carton test where the product is fragile
- Clear pass, fail or conditional verdict, and the inspector's name
The mistake that costs the most
Paying the balance before the report arrives. Once the factory holds the full payment, a failed inspection becomes a negotiation you will probably lose. Write into the purchase order that the balance is due after a passed inspection, and that rework or replacement is at the supplier's cost. Factories accept this far more often than buyers expect.
How we inspect
Our own inspectors go to the plant — no subcontracting — and you get a photo report the same day, in English, with a plain verdict rather than a list of hedges. If a batch fails we stay involved through the rework and re-check it. Message Jay on WhatsApp at +86 139 2274 9211 with your product and order quantity for a quote.
