SummaryJiangsu Tedrail Industrial Co., Ltd. is identified as a Chinese manufacturer/factory specializing in railway-related products, including carbodies, passenger coaches, couplers, freight cars, train parts, and cold-bending parts. The supplier reports more than 10 production lines, 50 years of combined R&D-engineer experience, 11–20 quality-control staff, and stated production capacities across several railway product categories. It reports ISO 9000 and ISO 9001 certification and describes multiple material and product testing methods. Export activity is indicated by 90% export sales, self-managed import/export rights, and exporting activity since 2008. Evidence is insufficient to verify financial strength, customization performance, after-sales capability, or a substantial customer-case history. The factory address differs slightly between records, which should be clarified during due diligence.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company located in Jiangsu, China. Its stated commercial scope and product keywords are concentrated in industrial equipment and railway products, including carbodies, couplers, freight cars, train parts, and interiors.

CertificationsThe supplier reports holding ISO 9000 and ISO 9001 certification. The slices do not provide certificate numbers, issuing bodies, validity dates, or scope, so the existence is reported but its current validity cannot be independently assessed.

R&D capabilityThe supplier reports 50 total experience among R&D engineers and describes a technical team experienced in railway-product design, manufacture, and inspection. It also lists chemical, metallographic, mechanical, ultrasonic, magnetic, impact, and hardness testing, supporting technical competence, but no explicit evidence of patented technology, new-product development, or measurable innovation outcomes is provided.

Production capacityThe supplier reports more than 10 production lines, 11–20 quality-control staff, and stated annual capacities of 200 carbodies, 1,200 coupler sets, 500 freight cars, 10,000 train-part sets, and 3,000 tons of aluminum profiles. Its 90% export-sales share and self-managed import/export rights further indicate established production and export operations.
