AI-Powered supplier vetting
SummaryHDSafe Technologies Co., Ltd. is identified as a China-based limited company and factory in Fujian, established in 2003. The supplier reports eight production lines, 21–30 quality-control staff, and annual outputs of 50,000 sensor faucets, 30,000 automatic urinal flushers, and 30,000 automatic toilet flushers. It holds an ISO 9001:2015 management-system certificate and describes more than a decade of experience in automatic hygiene products. Its products are marketed internationally, with exports representing 51%–70% of total sales, and it reports sales support through worldwide agents and distributors. However, the evidence is inconsistent in places: one record lists 18 total employees while another lists 21–30 quality-control staff, and a separate product list contains unrelated items. Evidence is insufficient to verify financial strength, customization execution, or a substantial customer track record.
Supplier typeThe supplier is explicitly classified as a factory and as a limited company, with the legal name HDSafe Technologies Co., Ltd. and operations in Fujian, China. This supports identifying it as a manufacturing supplier rather than only a trading intermediary.
CertificationsThe supplier explicitly reports holding an ISO 9001:2015 certificate for its management system. The slice does not provide certificate scope, issuing body, validity period, or product-specific certifications, but the stated management-system certification is positive evidence.
After-Sales capabilityThe supplier states that its GEEO and 3U brands have a worldwide network of local agents and distributors providing sales support. This indicates some channel-based support capability, although the evidence does not specify warranty terms, service response times, spare-parts arrangements, or technical-support procedures.
R&D capabilityThe supplier describes its development team as integrating the latest technological and design innovations and reports more than a decade of experience developing automatic hand dryers, electronic faucets, and motion flush valves. Nevertheless, only one year of total R&D-engineer experience is recorded, and no patents, R&D investment, or independently verified new-product results are provided.
Production capacityReported production indicators include eight production lines, annual output of 50,000 sensor faucets, 30,000 automatic urinal flushers, and 30,000 automatic toilet flushers, plus 21–30 quality-control staff and a 1,000 m² manufacturing plant. The supplier also reports order fulfillment within 15 workdays in both peak and off-peak seasons. The records contain a material inconsistency because total employees are listed as 18 in one slice while quality-control staff alone are listed as 21–30, so capacity claims warrant verification.
