AI-Powered supplier vetting

SummaryGuofeng is a high-tech manufacturer and supplier of environmental wood-plastic composite products, established in 2004 and headquartered in Anhui. It reports eight production lines, annual WPC output of 40,000 tons, export activity of 20 years, and exports representing 51%–70% of sales. The supplier offers sample-based, fully customized, and flexible customization services, and provides OEM services for well-known brands. It holds ISO9001:2015, ISO45001:2018, ISO14001, and CE-related certifications. However, it reports no available SDK, no in-stock capacity, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with related subcontractors. Service procedures exist, but supporting records, approved-supplier signatures or dates, and complaint or corrective-action records are absent. No Fortune 500 cooperation is reported, and the available information does not establish detailed customer cases.

Supplier typeThe supplier is described as a high-tech enterprise engaged in R&D, production, sales, and service of environmental wood-plastic composite products. Its company type is listed as combined, and it operates under a manufacturer and supplier identity rather than an offshore company structure.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, plus CE and other product-compliance certifications. These stated certifications provide explicit evidence of certification coverage across quality, occupational safety, environmental management, and product compliance.

Production capacityThe supplier reports eight production lines, annual WPC output of 40,000 tons, approximately one-month lead times in both peak and off-peak seasons, and 50 qualified service-capability suppliers. However, it has no valid manufacturing-capacity contract with related subcontractors, so production capacity is evidenced but manufacturing-governance coverage is incomplete.

Customization capabilityThe supplier offers customization from samples, full customization, and flexible customization, while also providing OEM services for well-known brands. These statements explicitly demonstrate broad product customization and OEM capability.
