AI-Powered supplier vetting

SummaryHong Kong Yushengchang Technology Co., Limited is identified as a China-based trading company established in 2013, with operations and manufacturing information centered in Shenzhen, Guangdong. Its stated product range focuses on GPS trackers, smartwatches, wearable devices, and smart AI glasses. The supplier reports CE, RoHS, GSMA/TAC, Anatel, and FCC-related certifications, a 103.0 m² manufacturing plant, three production lines, and 6–10 quality-control staff. It reports export activity since 2013 and that 90% of sales are from exports. The available information supports a positive assessment of certification coverage, product innovation, and stated production infrastructure. Evidence is insufficient to verify after-sales service, customization, or customer cases. Corporate identity and operating details are inconsistent across the records, including Hong Kong and Shenzhen legal/company references, so verification would be appropriate.

Supplier typeThe supplier is explicitly described as a Trading Company and Limited Company, while its product descriptions present it as a provider of GPS positioning and wearable technology. Records identify Hong Kong Yushengchang Technology Co., Limited and Shenzhen Yushengchang Technology Co., Ltd., indicating trading and Shenzhen operating/company information but not a single unambiguous legal structure across all records.

CertificationsThe supplier explicitly states that it has CE, RoHS test reports and certificates, GSMA/TAC certification, an Anatel certificate for Brazil, and an FCC ID. These stated certifications provide direct evidence of compliance-related documentation for its electronics and connected-device products.

R&D capabilityThe supplier states that it develops GPS positioning solutions, IoT and wearable products, Bluetooth smartwatches, smart AI glasses, and trackers for children, elderly users, vehicles, pets, and personal security. Its stated technical agility and broad connected-device portfolio support an affirmative assessment of product innovation capability.

Production capacityThe records identify a Shenzhen factory location, a 103.0 m² manufacturing plant, three production lines, and 6–10 quality-control staff. The supplier also reports production of GPS trackers, smartwatches, and smart AI glasses, plus export operations since 2013; these details provide explicit evidence of operating production capability, although the reported output information is inconsistently formatted.
