AI-Powered supplier vetting

SummaryTIANYI SUNS PIPE & FITTINGS CO., LTD. is a China-based manufacturer/factory with ISO 9001 certification and stated quality assurance. It reports raw-material traceability, complaint-handling procedures with records, new-product activity, ODM and customization services, and pipeline-product capacity of 40,000 tons. Its export markets include Eastern Europe, the Middle East, Western Europe, and Africa, with 51%–70% of sales reportedly from exports. Service infrastructure is limited: it reports no inventory, overseas warehouses, overseas showrooms, overseas agents, branches, or overseas-service countries. Peak-season lead-time information is inconsistent across the provided records, ranging from one month to 2–3 months. Financial records are identified for 2020–2022, but no assessable financial results are provided. No customer cases are documented.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and operates as TIANYI SUNS PIPE & FITTINGS CO., LTD. in Shanxi, China. This supports direct manufacturing classification rather than a trading-only classification.

CertificationsThe supplier reports holding ISO 9001 certification for its management system. The provided information does not identify the certification scope, issuing body, or validity period, but the stated certification is explicit evidence of certification holding.

After-Sales capabilityThe supplier has a clear customer-complaint procedure with followed records and has participated in the Canton Fair. However, it reports no in-stock service capacity, overseas warehouse, overseas showroom, overseas agent or branch, and zero countries with overseas services; its service assessment has records but no written procedure.

R&D capabilityThe supplier reports launching new products during the past year, provides ODM services, and has R&D engineers with 11–20 years of total experience. It does not provide an SDK and does not offer OEM services for popular brands, but these limitations do not negate the documented product-development and ODM capabilities.

Production capacityThe supplier reports pipeline-product capacity of 40,000 tons and identifies itself as a manufacturer, with 21–30 quality-control staff. It has no in-stock service capacity, while outsourcing procedures and manufacturing contracts have unknown status; the stated production-capacity evidence nevertheless supports a production capability assessment.

Customization capabilityThe supplier explicitly offers customization from samples and designs and provides ODM services. These statements directly support both sample/design customization and original-design manufacturing capability.
