Start with the buyer decision
The inspection or audit scope should answer a real sourcing question: supplier identity, factory capability, product conformity, finished-goods readiness or shipment loading.
Independent inspection support in China
About YiwuQC
YiwuQC supports overseas buyers sourcing products from China with third-party product inspection, supplier verification, factory audit and shipment-stage observations.
Who we are
Buyer-side inspection support based in Yiwu
YiwuQC is based in Yiwu, Zhejiang. Inspection work is planned around the actual supplier or factory location, product, order stage, requested scope and schedule rather than assuming that every order needs the same checklist or service.
Our role is to provide buyer-side observations and documented evidence against agreed references such as specifications, approved samples, purchase information, artwork, packaging requirements and known risks where those materials are available.
YiwuQC is operated by Yiwu Kawensi Trading Co.,Ltd, registered in Yiwu, Zhejiang in 2019. The company identification and direct business contact details published on this page help buyers identify the legal entity behind the YiwuQC brand.
How we work
Inspection built around evidence, scope and buyer requirements
The useful inspection question is not simply whether a product is “good”. The scope should identify what evidence the buyer needs, what reference controls the check and what can realistically be observed at that order stage.
Use buyer references
Specifications, approved samples, drawings, tolerances, artwork, order information and known concerns provide stronger inspection criteria than generic assumptions about quality.
Match the service to the stage
Supplier verification, factory audit, product inspection, pre-shipment inspection and loading supervision provide different evidence and should not be treated as interchangeable.
Document findings clearly
Photos, observations, measurements, basic agreed checks, quantities, packaging findings and visible limitations should make it clear what was and was not confirmed.
Keep limitations visible
Sampling, access, timing, sealed goods, unavailable records and unclear specifications affect what an inspection can establish and should not be hidden behind broad conclusions.
Do not replace specialist evidence
Standard onsite inspection does not replace laboratory testing, engineering validation, regulatory certification, legal due diligence or other specialist assessment.

What standard inspection does not prove
Independent inspection can reduce uncertainty, but it should not be presented as a guarantee or as a replacement for evidence that requires a different method or specialist authority.
- Inspection observations apply to the agreed scope, accessible evidence and the time of the visit.
- Sampling does not prove that every unit in an order is defect-free.
- A standard onsite visit does not certify product safety, regulatory compliance, laboratory performance or material composition.
- Factory or supplier observations do not guarantee solvency, legal compliance, future capacity or future commercial performance.
- Technical products may require methods, equipment or specialist expertise that must be agreed before the assignment.
