AI-Powered supplier vetting

SummaryHandan Haosheng Fastener Co., Ltd. is a China-based limited company established in 2007 with 103 employees and a stated scope covering processing and sales of standard parts and power fittings. It demonstrates broad customization, ODM, recent product development, OEM service for known brands, documented quality procedures, five quality inspectors, and production equipment for annealing, forming, drawing, heading, screw making, and tempering. Service support is comparatively limited: there is no reported inventory, overseas warehouse, showroom, overseas agent or branch, and no valid manufacturing-capacity contract with related subcontractors. Complaint handling has a procedure but lacks written records. ERP integration is reported, while certification holdings and detailed customer references are not provided. Financial assessment is limited because the supplied financial records are incomplete and are not evaluated here with monetary figures.

Supplier typeThe supplier is identified as Handan Haosheng Fastener Co., Ltd., a Chinese limited company located in Handan, Hebei, established in 2007, with 103 employees. Its stated business scope is processing and sales of standard parts and power fittings, subject to required approvals for restricted activities.

After-Sales capabilityThe supplier has a corrective and preventive action procedure with follow-up records and written service-assessment procedures, but complaint handling has no written records. It reports no inventory, overseas warehouse, showroom, overseas agent, or branch, and lists zero countries with overseas services; it has participated in Fastener Fair Global 2025 and can serve through stated trade terms.

R&D capabilityThe supplier reports new products during the past year, provides ODM services and multiple customization routes, and uses an ERP system for production, procurement, quality control, and logistics digitization. However, no usable SDK is available, which limits evidence of software-development integration capability.

Production capacityProduction evidence includes five quality inspectors, dedicated equipment for annealing, shooting, drawing, cold heading, screw making, and tempering, plus uniformly followed finished-product inspection instructions and a one-month stated lead time in both peak and off-season. The absence of a valid manufacturing-capacity contract with related subcontractors is a documented control weakness.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. The same broad capability is reported in both R&D and design-capability records, indicating a strong stated ability to adapt products to customer requirements.
