AI-Powered supplier vetting

SummaryHaiYan OuYaTe Automobile Fittings Co., Ltd. is a limited company manufacturing automotive brake linings, auto parts, and high-strength fasteners. It reports broad customization and ODM capabilities, recent new-product activity, four production lines, stated brake-lining productivity, and 20 quality inspectors. The supplier has provided OEM services to well-known brands and has exported for 10 years, but exports represent only 1%–10% of sales and it reports no overseas service presence, warehouse, showroom, agents, branches, or offline trade-show participation. Quality and service procedures exist in several areas but lack written records. Audit information identifies TUV Rheinland, with a reported audit period from May 25, 2024 to May 24, 2025; the stated evaluation result is 0, but the meaning of that score is not provided.

Supplier typeThe supplier is identified as HaiYan OuYaTe Automobile Fittings Co., Ltd., a limited company with no larger-company group affiliation. Its stated business scope covers automotive brake linings, auto parts, and high-strength fasteners, while its primary and offered product is brake lining.

After-Sales capabilityThe supplier reports procedures for corrective and preventive actions and customer complaints, but no written records are available. It has no overseas warehouses, showrooms, agents, branches, or overseas service countries, limiting the documented international after-sales infrastructure.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services. It also reports no available SDK, but SDK availability is not sufficient by itself to assess manufacturing-product innovation; the stated new-product activity supports a positive indication.

Production capacityThe supplier reports four production lines, equipment including molding, grinding, cleaning, drilling, and lettering machines, 20 quality inspectors, and annual brake-lining productivity of 12,361 tons. However, it does not continuously reconcile quantities for each batch or production lot, indicating a documented production-control weakness despite substantial stated capacity.

Customization capabilityBoth records list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM availability, providing explicit evidence of broad customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands and has exported goods for 10 years. These claims indicate relevant customer and market experience, although no brand names, project details, or verifiable case descriptions are provided.
