SummaryThe supplier demonstrates ODM and OEM service capability, broad customization options, and substantial export orientation, with 90% of total sales from exports. It maintains documented procedures for supplier-service assessment, corrective actions, and customer complaints, and reports peak- and off-season lead times within 15 working days. However, it has no overseas warehouse, showroom, agent, or branch, and reports no new products launched in the past year. R&D resources appear limited, with one R&D engineer and no available SDK; quality assurance, traceability, environmental compliance, and fire-drill status are largely unknown. No certification information or customer case details are provided. Financial records are indicated for 2021–2023, but their results cannot be assessed from the available information.

Supplier typeThe supplier is positioned as a resin and composite-materials manufacturer offering ODM, OEM, and multiple customization services. Its export share is stated as 90%, but it has no overseas warehouse, showroom, agent, or branch, while having participated in the Moscow Composite-Expo.

After-Sales capabilityThe supplier has a clear procedure and followed records for handling customer complaints, documented procedures for supplier service capability, and corrective/preventive-action records. Service quotations support FOB, CIF, CFR, and EXW terms, with stated lead times within 15 working days in both peak and off-season periods.

R&D capabilityThe supplier offers ODM services and lists formulation development and new-product application among the R&D engineer’s responsibilities. Nevertheless, it launched no new products in the past year, has no available SDK, and reports only one R&D engineer, indicating limited demonstrated innovation output.

Production capacityThe supplier reports five qualified service-capable suppliers, documented service-assessment and corrective-action procedures, and a stated production focus on resin products.
