Quality
Most first orders have a quality problem. The only question that matters is whether you find it in the factory, where it costs a week, or at your warehouse, where it costs the order.

An inspection is a sample-based check of whether a batch matches an agreed specification. It counts, measures, tests and photographs. It produces a report you can act on, and it is the only evidence you will have if a dispute later becomes a conversation about who agreed to what.
It does not certify that every unit is good. It samples, and a sampling plan accepts that a proportion of defects may pass. It does not test to destruction, does not run reliability testing over weeks, and does not audit the factory's management system. Those are different services with different prices.
What it does extremely well is catch the four failures that account for most first-order problems: wrong specification, wrong quantity, wrong packaging, and a cosmetic standard that nobody actually defined.
For a first Canton Fair order, the second is the one not to skip. The third is a cheap add-on when the container is loaded at the plant. The first is worth the money when the product is new to the factory or the specification has changed.
AQL, acceptance quality limit, is a sampling standard: it defines how many defective pieces in a sample are tolerable before the batch is rejected. Three numbers do most of the work.
| Class | Typical limit | What counts |
|---|---|---|
| Critical | 0 | Safety failures, prohibited substances, anything that could injure a user |
| Major | 2.5 | Function broken, wrong size beyond tolerance, a defect a shopper would return the product for |
| Minor | 4.0 | Cosmetic flaws a shopper would notice but still buy |
Limits shown are the common commercial default at General Inspection Level II. The sampling size is set by the batch quantity, and stricter limits mean larger samples and higher cost.
The number that matters is not the AQL but the definition attached to it. "Major defect" means nothing until someone writes down what a major defect is for this product: a seam that opens under 5 kg of load, a logo 3 mm off centre, a battery that drops below 80 percent of rated capacity. That list is the inspection, and it is written by the buyer, not by the inspector.
The large international houses — SGS, Bureau Veritas, TÜV, Intertek, QIMA — are the default for buyers who need a report that a third party will accept, and for anything where a compliance document has to travel with the goods. They are consistent, they are not cheap, and their reports are recognised by retailers and by customs authorities.
Local inspection companies in Guangdong are cheaper and often faster to book, and quality varies from excellent to a photograph of a carton. The test is the report: does it contain measurements with tolerances, a defect classification, photographs with the carton number visible, and the inspector's name?
Cost sits in the range of a few hundred US dollars per man-day for a standard factory check on a normal-size order, plus travel where the site is remote. A three-day inspection on a large order costs three times a one-day inspection, which is why the brief matters: a well-defined scope can be checked in a day.
The inspector will be someone who has never seen your product, standing in a factory where the manager wants them to finish. What they can check is exactly what your brief defines.
Send the same specification to the factory at the order stage. An inspection against a standard the factory has never seen is a dispute, not a check.
Most first inspections find something. The useful question is not pass or fail but what the failure costs to fix, and there are four outcomes worth having agreed in advance.
Build the calendar backwards from the vessel, not forwards from production. Inspection needs three to five days' notice, rework needs one to two weeks, and the second inspection needs another booking. On a first order, that is three weeks of buffer that has to exist before the booking is made.
Q How much does a pre-shipment inspection cost in China?
A few hundred US dollars per man-day for a standard factory check, plus travel for remote sites. International inspection houses cost more than local providers and produce reports that third parties accept more readily.
Q How much notice does an inspection need?
Three to five working days is normal. During peak season, or for a large order requiring more than one day on site, book earlier.
Q What does AQL 2.5 mean?
It is the acceptance quality limit for major defects at General Inspection Level II: the sampling plan defines how many major defects in the sample are tolerable before the batch is rejected. Critical defects are normally set at zero.
Q Should I inspect a Canton Fair first order?
Yes. First orders with new suppliers are exactly where specification, packaging and cosmetic standards diverge. The inspection costs a fraction of a failed order and gives you evidence if a dispute follows.
Q Can I inspect before the goods are packed?
You can, and for a new product an end-of-production check before the cartons are sealed is usually the better moment, because defects are easier to see and rework is easier to do.
