AI-Powered supplier vetting

SummaryDadao Chemicals Co., Ltd. is identified as a Chinese manufacturer/factory in Shandong producing and trading chemical products, including PVC resin and several solvents and surfactants. The supplier reports ISO 9001 certification, OEM service for well-known brands, SDK availability, documented corrective-action and complaint-handling procedures, inventory capability, and flexible customization. Production information states PVC resin output of 75,000 tons, with reported order fulfillment within 15 working days in both peak and off-peak periods. However, quality assurance, traceability, testing-equipment status, environmental assessment, fire-drill capability, outsourcing controls, and raw-material traceability remain unknown or limited. No new products were launched in the previous year, and overseas warehouse and showroom capabilities are absent. Customer-specific cases are not provided.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and Limited Company located in Tai’an, Shandong, China, with chemicals as its commercial trade category. Its stated product scope includes PVC resin, paraffin wax, calcium carbide, SLES, LABSA, ethanol, isopropyl alcohol, and caustic soda.

CertificationsThe supplier reports holding ISO 9001 certification, providing explicit evidence of a certified supplier management or quality-management system. No additional certifications are stated in the provided information.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaint handling, supporting an established service-response process. It also reports in-stock service capability, although overseas warehouse and overseas showroom services are unavailable.

R&D capabilityThe supplier reports R&D engineers with 11–20 years of total experience, SDK availability, OEM capability for well-known brands, and broad design customization options. However, it launched no new products in the previous year, so the evidence supports technical development capability but not recent product innovation.

Production capacityThe supplier reports PVC resin productivity of 75,000 tons, inventory capability, and order fulfillment within 15 working days during both peak and off-peak seasons. It is also identified as a factory, but the records show only eight total employees and do not clarify whether the stated output is fully owned production capacity or how quality testing is supported.

Customization capabilityThe supplier explicitly offers OEM services for well-known brands and supports customization from samples, designs, full specifications, minor modifications, and flexible requirements. SDK availability further indicates support for certain technical integration needs.
