AI-Powered supplier vetting

SummaryShandong TFN Bearing Industry Co., Ltd. is identified as both a trading company and manufacturer/factory in Shandong, China, with operations dating to 1985. It offers a broad bearing portfolio, reports more than 10 production lines, over 6,000 bearing varieties, annual capacity of 70 million sets, and 31–40 quality-control staff. The supplier lists multiple management-system certifications and states that its technical center develops special-purpose bearings to customer requirements. Export activity covers multiple global regions, with reported delivery times within 15 working days in both peak and off-peak seasons. Trade records show transactions involving Ecuador and Kazakhstan, including 269 recorded transactions for bearings with one Ecuadorian buyer. Evidence is insufficient to assess after-sales service and financial credibility because the available financial information is excluded from this assessment and service procedures are not described.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, and is based in Shandong, China. This indicates combined manufacturing and trading capability rather than a purely intermediary profile.

CertificationsThe supplier lists BSCI, ISO 9000, OHSAS/OHSMS 18001, TS 16949, ISO 9001, ISO 14001, ISO 14000, ISO 20000, HSE, ISO 14064, and QC 080000 certifications. The slices do not provide certificate numbers, validity dates, or scope, but they explicitly document extensive certification holdings.

R&D capabilityThe company states that it has 35 years of bearing innovation and production-management experience, a technical center, 6–10 years of total R&D-engineer experience, and the ability to develop special-structure, special-performance, and special-purpose bearings according to customer requirements. These statements provide explicit support for product-development capability.

Production capacityThe supplier reports more than 10 production lines, annual capacity of 70 million sets, more than 6,000 bearing varieties across nine types, 31–40 quality-control staff, and delivery within 15 working days in both peak and off-peak seasons. These stated figures support substantial production breadth and operational capacity.

Customization capabilityThe supplier explicitly states that its technical center designs and develops bearings with special structures, performance characteristics, and purposes according to customer requirements. This directly supports customization capability.

Client casesThe supplier states that its business reaches more than 60 countries and lists global export markets. Trade records also show transactions involving Ecuador and Kazakhstan, including 269 recorded transactions for bearings with an Ecuadorian buyer, although the records provide limited customer detail and do not independently verify all broader market claims.
