AI-Powered supplier vetting

SummaryTianjin Boya Metal Products Co., Ltd. is a China-based trading company established in 2017 with 18 employees and a stated business scope covering metal materials, wire mesh, hardware, building materials, and related products. The supplier reports access to wire and nail mills, advanced production equipment, and annual production capacity of approximately 50,000 tons, but its entity is identified as a trading company and associated companies are in wholesale and retail. It demonstrates customization options and OEM service for well-known brands, but does not provide 3D software design, ODM, SDK, or reported new-product development. Service-management controls are weakly documented: no written procedures or records were provided for service assessment, corrective actions, or complaint handling. It has no overseas warehouse, showroom, agent, or branch, but has participated in an offline trade fair. Financial information is only represented by year labels, without substantive financial results, so credibility...

Supplier typeThe supplier is explicitly identified as a trading company, with wholesale and retail as the associated-company industry and a broad import-export business scope for metal, hardware, construction, and related products. Although it describes its own wire and nail mills, the legal and business classification provided is Trading Company.

After-Sales capabilityThe supplier reports no written procedures or records for customer complaint handling, service-capability assessment, or corrective and preventive actions. It has six qualified service suppliers and supports stated quotation and payment terms, but the documented after-sales management system is insufficiently evidenced.

R&D capabilityThe supplier states that it is not a professional technical supplier, had no new products during the past year, and does not offer ODM, 3D software design, or SDK services. These explicit limitations indicate weak demonstrated innovation and technical-development capability.

Production capacityThe company describes advanced production equipment, its own wire and nail mills, and approximate annual capacity of 50,000 tons; it is located near Xingang Port and Tianjin Airport. However, the legal entity is classified as a trading company, so the extent of directly controlled production capability is not fully clear, while the stated capacity is positive evidence.

Customization capabilityThe supplier reports customization ranging from design-based and full customization to flexible and minor customization, and also states that it provides OEM services for well-known brands. It does not provide ODM, 3D software design, or SDK services, but the stated customization and OEM capabilities are explicit strengths.
