AI-Powered supplier vetting

SummaryAozhan Hardware Fastener Co., Ltd., established in 2012 in Guangxi, is identified as a stainless-steel bolt and hardware-fastener manufacturer. It reports OEM service for popular brands, ODM availability, broad customization options, and 100% finished-product inspection. However, finished-product checks are performed by packing staff, raw materials lack traceability, and there is no documented service-capability assessment procedure or written corrective-action records. The supplier reports no in-stock capacity, overseas warehouse, showroom, agent, branch, overseas service coverage, or offline trade-show participation. No new products were reported in the past year, and no SDK or ERP-based process management is available. Financial information is insufficient for a positive credibility assessment because the provided historical figures are recorded as zero.

Supplier typeThe supplier is identified as Aozhan Hardware Fastener Co., Ltd., established in 2012, specializing in producing and selling hardware fasteners. Its representative title specifically identifies stainless-steel bolt and screw production, supporting classification as a hardware-fastener manufacturer.

After-Sales capabilityThe supplier reports a lead time within 15 workdays in both off-season and peak season and accepts multiple quotation and payment terms. However, it has no in-stock capacity, overseas warehouse, showroom, agent, branch, or overseas service coverage; service procedures are incompletely documented, with some supplier names provided but no written corrective-action records.

R&D capabilityThe supplier offers ODM services and multiple forms of design customization, but reports no new products during the past year, no available SDK, and no ERP, OA, CRM, or SAP-based digital process integration. This indicates design-service availability but limited evidence of recent product innovation or digitalized innovation infrastructure.

Production capacityThe supplier has operated since 2012, specializes in hardware fasteners, reports 100% finished-product inspection, and has five quality assurance and control inspectors. Nevertheless, raw materials are not traceable and finished-product checks are performed by packing staff, so production quality-control maturity is mixed.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad customization and design-service capability.
