AI-Powered supplier vetting

SummaryTianchang Guer Fastener Trading Co., Ltd. supplies fasteners and related precision metal parts, including rivets, screws, bolts, nuts, pins, bushings, spacers, sleeves, and tubes. It states that it can manufacture nonstandard metal products from customer drawings or samples, but the available data also indicates no private-mold R&D, no 3D design services, no ODM, no SDK, and no new products in the past year. Service procedures exist for supplier evaluation, corrective actions, and complaints, but supporting records are absent or incomplete. The supplier reports no overseas warehouse, showroom, overseas agent or branch, or offline trade-show participation. Its quality-control staff count is below five, while stated lead times are within 15 working days in both peak and off-peak periods. No supplier-management-system certification is listed. An audit by TUV Rheinland is recorded, but the audit result is given only as “0,” without an explanatory interpretation. Financial data identifies reporting years but...

Supplier typeThe supplier is identified as a fastener supplier and describes its products as rivets, screws, bolts, nuts, pins, inserts, self-clinching fasteners, shafts, bushings, spacers, sleeves, and tubes. Its stated ability to manufacture nonstandard metal products from customer drawings or samples indicates a manufacturer/trading-company profile focused on customized metal components, although the legal name includes “Trading Co., Ltd.”

CertificationsThe supplier-management-system certification field is explicitly listed as “NIL,” so no certification is evidenced in the provided data. A TUV Rheinland audit is recorded with dates, but the audit result is shown only as “0” and does not establish certification holding.

After-Sales capabilityWritten procedures exist for service evaluation, corrective and preventive actions, and customer complaints, but the supplier has no records supporting implementation. It also reports no overseas warehouse, showroom, overseas agent or branch, or prior offline trade-show participation, limiting demonstrated service infrastructure.

R&D capabilityThe supplier reports no private-mold R&D, no professional technical-supplier capability, no 3D software design service, no ODM service, no SDK availability, and no new product in the past year. Although one slice states a total of one year of R&D-engineer experience and another describes strong R&D capacity, the explicit capability fields indicate limited demonstrated innovation infrastructure.

Production capacityThe supplier lists a broad range of fastener and precision metal products, reports lead times within 15 working days during both peak and off-peak seasons, and states that samples can be completed in 3–7 days with production in 10–15 days after specified confirmation. However, quality-control staffing is below five, so production responsiveness is evidenced more clearly than production scale or quality-system depth.

Customization capabilityThe supplier explicitly accepts customer design drawings or samples for custom metal parts and states that it can manufacture nonstandard metal products. It also describes sample development within 3–7 days based on available materials, supporting a demonstrated sample- and drawing-based customization capability, though private-mold and 3D design services are not provided.
