AI-Powered supplier vetting
SummarySUNLIGHT FASTENER CO., LIMITED is a China-based limited company in Shanghai identified as both a trading company and manufacturer/factory, offering common fastener products. It provides ODM and broad customization services, but does not provide OEM services for popular brands and has no available SDK. Export activity is substantial at 90% of total sales, with self-operated import/export rights and four years of export experience. After-sales complaint handling has a clear procedure with follow-up records, while raw-material traceability and quality assurance status are unknown. The supplier has no overseas showroom, agents, branches, or reported offline trade-show participation. Financial information is recorded for several years, but the provided slices do not establish financial strength. The audit was conducted by TUV Rheinland, with a stated audit result of 0 and a report validity period that ended on 2024-12-26; the meaning of the score is not provided.
Supplier typeThe supplier is identified as a limited company and described as both a trading company and manufacturer/factory. Its product scope centers on bolts, screws, nuts, pins, thread rods, and flat washers, while another business-scope entry identifies it specifically as a trading company.
After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with follow-up records, which supports a documented after-sales process. Conversely, it has no overseas showroom, overseas agents or branches, and reports zero countries with overseas services, limiting demonstrated international service coverage.
R&D capabilityThe supplier explicitly provides ODM services, indicating design-and-manufacturing support. It does not have an available SDK and does not provide OEM services for popular brands, so the evidence supports some development capability but not broader technical integration or brand-OEM capability.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of a broad stated customization service range.
