AI-Powered supplier vetting
SummaryTianjin Hongxin International Trade Co., Ltd. is identified as a Chinese limited company with trade and manufacturing-related descriptions, focused on steel pipes, galvanized products, and related steel items. The available information indicates substantial production resources, including 15 ERW pipe lines, 6 precision pipe lines, more than 10 production lines overall, over 200 employees, and stated galvanized steel pipe productivity of 500,000 tons. ISO 9001 certification, quality-control personnel, R&D engineers, export activity, and sales to more than 30 countries provide positive evidence of operational capability. However, the materials do not establish after-sales procedures, specific customization services, verified financial strength, or detailed customer project references. The records also describe the company both as a manufacturer/factory and as a trading company, so its exact operating model should be clarified.
Supplier typeThe supplier is listed as a Manufacturer/Factory and is described as integrating production, processing, and trade, with a factory location in Bazhou/Langfang and a Tianjin trade center. Another record classifies it as a trading company, indicating a mixed manufacturing-and-trading profile rather than a purely single-type entity.
CertificationsThe supplier explicitly reports holding ISO 9001 certification. This supports the existence of a formal quality-management certification, although no certificate scope, issuing body, or validity period is provided.
R&D capabilityThe supplier reports 50 years of total R&D engineer experience and a product system covering galvanized, precision, black, bright, round, square, and special pipes. These details indicate some technical and product-development resources, but there is no direct evidence of patented technology, new-product development results, or advanced research facilities.
Production capacityProduction capability is strongly supported by 15 ERW steel pipe lines, 6 precision pipe lines, more than 10 total production lines, more than 200 employees, and stated galvanized steel pipe productivity of 500,000 tons. Reported fulfillment times are one month off-season and two to three months during peak season, indicating defined but seasonally extended lead times.
Client casesThe supplier states that its products have been sold in more than 30 countries, naming Canada, Singapore, and Turkey, and identifies export markets across multiple regions. The available trade record contains one associated buyer and one transaction, so international market reach is indicated but detailed, independently verifiable customer cases are limited.
