Sample Process in China: Types, Fees & Approval

Sample Process in China: Types, Fees & Approval By Zoey Zhang, Founder & Lead Sourcing Specialist Sourcing Guide 2026-08-28 Quick Answer A sample is the reference point for the whole order, not just something to look at. Once approved, mass production must follow it, so getting it wrong causes inspection, return and claim problems. The process covers four sample types, negotiating sample fees, verifying approval samples, shipping samples and five common pitfalls.

Get the sample wrong and inspection, returns and claims all go wrong with it. In ten years of running a sourcing agency in Guangzhou, we’ve seen too many orders die at the sampling stage: sample fee negotiations collapsing, approved samples not matching production, samples sent and never heard of again. This guide covers the full sampling process: the four sample types, how to negotiate sample fees, how to verify an approval sample, what to watch when shipping samples, and the five pitfalls that trip up most buyers.

Different stages use different samples, and mixing them up causes problems later.

Sample fees are the most common negotiation deadlock. Factories think “why should I make samples for free?”, buyers think “free samples show commitment.” There is no absolute standard — only arrangements that match the order value and cooperation stage: ArrangementWhen it fitsNegotiation pointsSample + shipping fully freeStandard products, low sample value (
