AI-Powered supplier vetting

SummaryTianchang Guer Fastener Trading Co., Ltd. supplies fasteners and other custom metal components, including rivets, nuts, screws, bolts, pins, bushings, spacers, sleeves, and tubes. It states that it can manufacture nonstandard metal products based on customer drawings or samples, but its documented design and innovation capabilities are limited: it has no private mold, 3D software design, ODM, SDK, or stated recent new-product development capability. The supplier has written procedures for service evaluation, supplier approval, corrective action, and complaint handling, but lacks corresponding records or complete approvals. No supplier-management-system certification is reported. Production-related information includes fewer than five quality-control staff, stated lead times within 15 working days, and broad export-market coverage. No overseas warehouse, showroom, agent or branch, or offline trade-show participation is reported. A TUV Rheinland audit is identified, but the stated audit result is 0 and no...

Supplier typeThe supplier is identified as Tianchang Guer Fastener Trading Co., Ltd., with fasteners as its primary product and a product range covering rivets, nuts, screws, bolts, pins, bushings, spacers, sleeves, and tubes. Its description emphasizes manufacturing nonstandard metal products from customer drawings or samples, indicating a fastener and custom metal-parts supplier rather than a professional technical-services provider.

CertificationsThe supplier-management-system certification field is reported as NIL. Although a TUV Rheinland audit is listed with dates from April 23, 2025 to April 22, 2026, the stated audit result is 0 and the provided information does not identify a certification achieved or explain the result.

R&D capabilityThe supplier reports no private-mold R&D, no 3D software design service, no ODM service, no available SDK, and no new products during the past year. It reports one year of total R&D-engineer experience, so the available evidence indicates limited innovation infrastructure.

Production capacityThe supplier states that it manufactures nonstandard metal products and lists broad fastener-related capabilities. Reported lead times are within 15 working days in both off-peak and peak seasons, while quality-control staffing is fewer than five people; these details support order-production capability but provide limited evidence regarding scale and quality-control depth.

Customization capabilityThe supplier explicitly accepts customer design drawings or samples for custom metal parts and describes customization from samples. Sample completion is stated as 3–7 days when based on available yarns, and production is stated as 10–15 days after deposit and PP-sample confirmation, although the yarn-related wording is not fully consistent with the listed metal-product scope.
