AI-Powered supplier vetting
SummaryThe supplier is identified as a limited company and trade company located in Chongqing, China, offering diesel and fuel-system spare parts. It reports OEM service for popular brands, ODM availability, export sales of 90%, and stated production quantities for injectors, pumps, and related parts. However, the submitted information shows significant verification gaps: no certification evidence, no documented R&D audit materials, zero patents, no private-mold capability, no overseas agents, warehouses, showrooms, or stock service, and no written supplier-service assessment procedures. Financial data is referenced only by year without performance figures, so financial credibility cannot be judged. The supplier appears stronger in product supply, OEM/ODM availability, and export experience than in documented innovation, overseas service infrastructure, and formal management evidence.
Supplier typeThe supplier is explicitly described as a limited company and a trade company, located in Jiangbei District, Chongqing. Its offered products focus on fuel-system and diesel-engine spare parts, while no larger corporate-group affiliation is reported.
After-Sales capabilityThe supplier reports no in-stock service capability, overseas warehouse, overseas showroom, overseas agent or branch, and no participation in offline trade shows. It serves through Chongqing Port and accepts several quotation and payment terms, but the absence of overseas service infrastructure indicates limited documented after-sales support.
R&D capabilityThe supplier reports one year of total R&D-engineer experience, provides ODM service, and has an engineer who designs products according to customer requirements. However, it has no SDK, zero reported R&D patents, no private-mold capability, and no available R&D audit documentation, limiting evidence of independently documented innovation.
Production capacityReported annual productivity is 100,000 fuel injectors, 5,000 fuel pumps, 500,000 injector parts, and 100,000 pump parts. The supplier also reports a peak-season lead time of one month and an off-season lead time within 15 workdays, providing explicit evidence of product supply capacity, although valid manufacturing-capacity contract status remains unknown.
Customization capabilityThe supplier explicitly offers minor customization and ODM services, and its R&D responsibility includes designing products according to customer requirements. Nevertheless, it reports no private molds and no SDK, so the evidence supports limited rather than broad customization capability.
Client casesThe supplier states that it provides OEM services for popular brands, which is direct evidence of experience serving recognized-brand customers. No customer names, project details, references, or independently verifiable case documentation are provided.
