AI-Powered supplier vetting

SummaryShijiazhuang Deyoute New Material Technology Co., Ltd. is a China-based limited company in Hebei, identified as both a trading company and manufacturer/factory. Its product range focuses on mineral fibers, vermiculite, sepiolite, glass fiber, ceramic fiber, pumice powder, and related friction-material inputs. The supplier reports ISO 9001 certification, a registered trademark, export activity across multiple regions, and approximately 6–10 years of combined R&D engineer experience. Reported annual production is approximately 2,500–3,500 tons for mineral and related fibers and 6,500–7,000 tons for expanded vermiculite. SGS audit information is provided, but the audit result is recorded as “0,” and the audit validity ended on 2025-08-21. R&D services, OEM/ODM, quality assurance, traceability, overseas representation, and customer-specific design capabilities remain unverified. No financial data is assessed.

Supplier typeThe supplier is explicitly identified as both a trading company and a manufacturer/factory, with a limited-company structure and operations in Shijiazhuang, Hebei, China. This supports classification as a hybrid manufacturing and trading supplier.

CertificationsThe supplier states that it holds ISO 9000 quality-system certification and ISO 9001 certification. An SGS audit is documented, but the recorded audit evaluation is “0,” so the audit record does not provide clear positive validation beyond the stated certification information.

R&D capabilityThe supplier identifies fine pumice powder as a new product and reports 6–10 years of total R&D engineer experience. However, detailed R&D documentation, SDK capability, private-mold development, 3D design, and other structured R&D services are marked unknown, limiting verification of innovation strength.

Production capacityThe supplier reports production of asbestos-free mineral and related fibers at approximately 2,500–3,500 tons annually and expanded vermiculite at approximately 6,500–7,000 tons annually. Its broad product portfolio and stated manufacturing role provide explicit evidence of established production capability.
