Inspection, verification and quality control: MOQ, tooling, lead time and landed cost
Confidence 4/5 Established practice
Quality control is the cheapest insurance in importing and the first thing buyers cut. The arithmetic is unkind: an inspection costs a few hundred dollars and a bad production run costs the whole order plus the freight, plus the customer you lose quietly. The useful question is not whether to inspect but where in the process, because inspecting before shipment cannot fix a problem created at the drawing stage.
Quick answers
| Minimum order quantity | Not applicable. Inspection is a service priced per day or per man-day, with a one-day minimum and travel time charged outside major manufacturing regions. |
| Lead time | Book 3–5 days ahead. Report within 24–48 hours of the visit. Peak season and Chinese New Year reduce availability sharply, which is worth planning around. |
| Tooling | Not applicable. Where fixtures or gauges are needed for verification, they are specified and charged separately. |
| Unit cost | Roughly USD 100–350 per inspector-day in China for an agency inspection. Our own buyer attendance is included in the sourcing work rather than billed separately. |
| HS classification | The inspection service itself has no HS code — it is a service, not a shipped good. The goods being inspected are classified as they would be anyway, and an inspector who proposes a code is giving commercial advice, not a customs determination. |
| Certification | Inspection scopes are usually defined by AQL under ISO 2859-1, most commonly AQL 2.5 for major defects and 4.0 for minor ones, with critical defects at zero tolerance. The distinction that matters legally: a certificate of inspection reports what was found in a sample, while a certificate of conformity asserts the whole lot meets a standard. They are not interchangeable, and a buyer who needs the second should not accept the first. |
| Duty | Not applicable — inspection is a service and attracts no import duty. Where the fee is paid to a Chinese provider and remitted abroad, it is an ordinary business expense rather than part of the customs value of the goods, and it should not be included in the declared transaction value. |
Common mistakes
- Inspecting only at the end, when design and material choices are already locked in.
- Accepting a factory's own report as independent verification.
- Skipping inspection because the order is small; small orders are where a total loss is most painful relative to turnover.
- Not defining what a defect is before the inspection, which makes the report unactionable.
- Booking an inspection after the goods are already packed and the container is loaded.
