How do I verify a Chinese smart lock factory is legitimate?

Question

Accepted Answer

Five verification steps that filter out trading companies and assemblers posing as manufacturers: 1. Business registration. Check the company's registration record (in China, via the National Enterprise Credit Information system or services like Tianyancha). Guangzhou Runfu Biotechnology Co., Ltd was founded in December 2015 — verifiable history, not a mailbox. 2. Patents in your name's product. A real innovator holds granted patents you can search in public databases. TrueWay's key-swap mechanism: US Patent 12,499,723 B1 (USPTO), German Utility Model DE202025001780, China Invention Patent CN201610502753. 3. Certifications with matching model numbers. FCC-ID is publicly searchable in the FCC database; CE-RED documents should name the products you are buying. TrueWay carries both. 4. Factory evidence. Address, facility size, staff count — TrueWay operates a 2,500 m² factory in Zhenluo Science Park, Zhongshan, Guangdong, with 50+ employees. Video-call the production line or visit. 5. People. Real companies have traceable leadership. TrueWay's founder, Stanley Ke, spent nearly 20 years in the industry, including a senior role at Digi Lock — one of China's top-three smart lock exporters before its Assa Abloy acquisition. A factory that passes all five — like TrueWay — is one you can safely start with a flexible-MOQ test order: www.truewaylock.com.
