AI-Powered supplier vetting
SummaryGaoyao Jinhuida Hardware Products Co., Ltd. has operated in the industry for 20 years and manufactures floor springs, door handles, and shower hinges. It reports an R&D center, testing system, recent new-product development, ODM/OEM services, multiple customization options, and OEM service for recognized brands. Production capacity is substantial for the listed products, with exporting experience since 2012 and stated export sales participation of 21%–30%. The supplier also reports ISO9001:2015 certification, documented corrective-action and complaint-handling procedures, and testing against national standards. However, it reports no quality assurance capability, no in-stock capability, no overseas warehouse, showroom, agent, or branch, no offline trade-show participation, no valid manufacturing-capacity contract with related subcontractors, and no available SDK. Customer cases and detailed financial performance are not sufficiently evidenced.
Supplier typeThe supplier is a hardware manufacturer with 20 years of industry experience, its own brands, production equipment, production lines, an R&D center, and a testing system. Its stated products include floor springs, door handles, and shower hinges, and it exports through both agency channels and its own import/export rights.
CertificationsThe supplier states that products enter production after rigorous testing and reaching national standards, and it reports an ISO9001:2015 certificate. These statements provide explicit evidence of quality-system certification and standards-oriented testing, although no other certifications are identified.
After-Sales capabilityThe supplier describes pre-sale, sales, and after-sales service supported by qualified technical staff and marketing networks. It also reports documented procedures and records for customer complaints and corrective/preventive actions, but separately reports no quality assurance capability.
R&D capabilityThe supplier reports an R&D center, a detection system, new products during the past year, ODM capability, and multiple R&D customization modes. It also explicitly reports no available SDK, which limits evidence of software-development support but does not negate the stated hardware R&D capability.
Production capacityThe supplier reports advanced production equipment and lines, annual capacities of 500,000 floor springs, 400,000 door handles, and 400,000 shower hinges, plus one-month average lead times in both peak and off-season. Nevertheless, it reports no valid manufacturing-capacity contract with related subcontractors and no in-stock capability; the stated production data still supports manufacturing capability.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, alongside ODM services and OEM production. It also reports OEM service for recognized brands, providing direct evidence of broad customization and contract-manufacturing capability.
