AI-Powered supplier vetting

SummaryThe supplier is a China-based limited company established in 2013, with 15 employees and a Shanghai registered address. It is identified as a trade company, while its materials describe steel-structure design and manufacturing, factory production in Jiangsu, and multiple container and prefabricated-house products. The supplier reports four production lines, six to ten quality-control staff, stated annual capacities across light steel structures, prefab houses, container houses, and flat-pack containers, and export sales of 71%–90%. ISO 9001 and ISO 14001 certifications are reported, and an SGS audit record covers the period from May 28, 2025 to May 27, 2026, although the audit result is recorded as “0” without explanation. After-sales service and customization are mentioned, but specific service processes and advanced R&D/ODM/OEM capabilities are not evidenced. No customer names, project references, or independently verifiable customer cases are provided.

CertificationsThe supplier states it has ISO 9001 qualification and reports ISO 9001:2015 and ISO 14001:2015 certificates. These statements provide explicit evidence of management-system certification, although certificate numbers, issuing details, and validity dates are not supplied.

After-Sales capabilityThe company description explicitly promises excellent after-sales service and emphasizes customer service and stable cooperation. However, no evidence is provided on service personnel, response times, spare parts, warranty terms, or overseas service arrangements.

Production capacityThe supplier reports four production lines, three advanced roof and wall panel processing lines, six to ten quality-control staff, stated annual capacities for several prefabricated and container products, and steel-structure consumption of 500 tons per year. Its product range is broad and an SGS audit record is present, but the audit result is recorded as “0” without interpretation, so overall production reliability cannot be fully confirmed.

Customization capabilityThe supplier explicitly offers product designs and customized designs for customer projects, and its product portfolio includes multiple container and prefabricated-house formats. Nevertheless, no detailed customization workflow, engineering scope, 3D design support, or confirmed project examples are provided.
