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.
