AI-Powered supplier vetting

SummarySailing Commercial (Tianjin) Co., Ltd. is a China-based trading company established in 2017 with six employees. It offers semiconductor-related and power-control products and reports annual semiconductor-device productivity of 250,000 pieces, although its trading-company status means manufacturing capability is not clearly established. The supplier provides customization from samples and OEM services for well-known brands, but does not provide 3D software design, ODM, SDK, or broader professional R&D services, and reported no new products in the past year. Overseas sales represent 90% of total sales, with six years of export experience and self-operated import/export rights. Service procedures exist, but required records, approvals, and complaint documentation are absent. No overseas warehouses, showrooms, agents, branches, or offline trade-show participation are reported. Financial information is present for multiple years, but no financial figures or independent credibility evidence are provided.

Supplier typeThe supplier is identified as a limited trading company headquartered in Tianjin, China, with six employees and no larger-company affiliation. Its product scope includes thyristors, welding diodes, semiconductor devices, water-cooling power cables, and high-voltage control cabinets.

After-Sales capabilityThe supplier has written procedures for service assessment, corrective and preventive actions, and customer complaints, but no written records are maintained. It has no overseas warehouse, showroom, agent, branch, or offline trade-show presence; overseas service coverage is listed as zero countries, with debugging shown as the only service detail.

R&D capabilityThe supplier is explicitly not classified as a professional technical supplier, does not offer 3D software design, ODM, or SDK services, and reported no new products in the past year. Its stated R&D-related service is limited to customization from samples.

Customization capabilityThe supplier explicitly provides customization from samples and has OEM capability for well-known brands. It does not provide ODM services, 3D software design, or SDK support, indicating sample-based customization rather than broad product-development capability.
