Electronics Certification Guide for China Sourcing
14 resources tagged with "Certification"
Certification is the gate between a working prototype and a product you can legally sell — and for China-sourced electronics it spans FCC (US), CE/UKCA (EU/UK), PSE (Japan), SASO (Saudi), UL (safety), plus battery rules like UN 38.3 and IEC 62133-2. Each market has its own marks, but many share underlying IEC test reports, so a single CB Scheme report can feed several national approvals. The recurring sourcing problem is verifying that a supplier's certificate is from an accredited lab, matches your exact model and radio module, and is something you actually own.
Certification means holding accredited test reports tied to your specific BOM, not collecting PDFs from suppliers. The most common pitfall is modular-approval reuse gone wrong — a factory cites an ESP32 module's FCC ID but changes the antenna or layout, which voids the approval. We trace every certificate back to its issuing lab and the tested configuration.

FAQ
How do I check if a supplier's certificate is genuine?
Look up the certificate or FCC ID in the issuing body's public database (FCC grantee search, UL Product iQ, CB certificate lookup) and confirm the product, model, and applicant match. A certificate that names a different model or an unaccredited lab is a red flag.
Can one test report cover multiple markets?
Partly. An IEC-based CB Scheme report can be reused toward CE, SASO, and other national schemes with national differences, but US FCC and Japan PSE need their own testing. Plan which tests transfer and which must run separately.
How much should I budget and how long does certification take?
A wireless consumer device often runs roughly $4,000–$10,000 across FCC, CE, and safety, taking 4–8 weeks if the design is stable. Battery certs (UN 38.3, IEC 62133-2) and Gulf SASO add cost and time on top.
