Shenzhen is the world's electronics capital. Huaqiangbei market alone has 50,000+ shops selling every component imaginable. But electronics sourcing comes with unique risks.

Certifications Are Non-Negotiable

Before placing any electronics order, confirm certifications exist: CE (Europe), FCC (USA), RoHS (hazardous substances), UL (safety). Ask for certificate copies. Verify them on the issuing body's website. We've seen forged certificates — always verify.

Component Quality Varies Wildly

"Same specs" doesn't mean same quality. Two USB cables can look identical but one uses copper, the other aluminum-coated steel. Battery cells from brand-name manufacturers (Samsung, LG, Panasonic) cost 3-5x more than generic cells — but they don't catch fire. Specify brand-name components in your contract.

Firmware and Software

Smart devices need software. Who writes it? Who owns it? Can it be updated? What happens if there's a bug? Get ownership and update rights in writing. We've seen factories disappear, leaving clients with devices they can't update.

Testing Protocol

For electronics orders over $5,000, invest in third-party testing: safety testing, EMC testing, and performance testing. Cost: $500-2,000 depending on product complexity. It's cheaper than a container of defective goods.
