Different questions need different evidence
Supplier and factory
Supplier information and available records can be compared for consistency; facility audits address observable processes and quality arrangements.
Products and finished goods
Selected units can be checked against agreed specifications, workmanship and packing references. Timing and sampling affect what can be concluded.
Shipment and loading
Available cartons, quantities, marks and loading activity can be observed at the relevant stage, but loading checks do not replace detailed product inspection.
Separate laboratory evidence
Need product testing beyond onsite inspection?
YiwuQC can help coordinate laboratory-testing enquiries with suitably authorised or accredited independent local labs. Laboratory tests and original reports are performed and issued by the laboratory, not YiwuQC.

Before you book
What to send for a useful inspection scope

- Specifications, samples or inspection criteria
- Known concerns and preferred inspection timing
Buyer questions
Inspection services FAQ
Which inspection service should a first-time buyer choose?
Start with the unresolved decision. Supplier identity may point to verification; facility and process questions to an audit; product conformity to product inspection; finished-goods release to PSI; and loading questions to loading inspection.
Can one visit answer every supplier and product question?
Usually not well. Different evidence is available at different sites and order stages. Define priorities and consider separate stages when supplier, process, product and shipment questions are all material.
Does inspection guarantee acceptable goods?
No. Findings are limited by scope, access, references, timing and sampling. The buyer interprets them with other commercial and technical information.
What should be ready before requesting inspection?
Prepare the site, product, order stage, quantities, specifications, known risks, requested checks and decision timing. Missing inputs should be identified rather than replaced by assumptions.
Can YiwuQC review inspection requests outside Yiwu?
Yes. You can send the factory address and requested timing for locations in Zhejiang, Jiangsu, Anhui and other Chinese sourcing regions. The inspection scope, access and scheduling need confirmation before booking.
