AI-Powered supplier vetting

SummaryTAIZHOU EASTAR TECHNOLOGY Co., Ltd. is identified as a valve-focused production, sales, and service supplier offering multiple industrial and medical gas valve products. It has forging, cutting, drilling, and CNC facilities, documented finished-product inspection instructions, and broad customization capabilities. The supplier reports that 90% of total sales are exports and has self-operated import/export rights, with FOB, CIF, CFR, and EXW quotation terms. Quality assurance, complaint-handling, and corrective/preventive-action procedures are documented and followed. However, the available information confirms no 3D software design service, no valid manufacturing-capacity contract with related subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Financial records are referenced for 2021–2023, but no financial performance details are provided. A TUV Rheinland audit is identified, although the audit result is recorded as 0 and...

Supplier typeThe supplier is explicitly described as a professional technical supplier and as a factory integrating valve production, sales, and service. Its stated business scope includes valve research and development and technical services, while its company type is listed as combined.

After-Sales capabilityThe supplier has documented and followed procedures for handling customer complaints and corrective/preventive actions, and its description refers to pre-sales and after-sales service. Nevertheless, it reports no inventory, overseas warehouse, overseas showroom, overseas agents or branches, and no overseas service countries, limiting evidence of localized after-sales support.

R&D capabilityThe supplier is identified as a professional technical supplier with research and development capability, and its business scope includes valve research and development and technical development services. It also states that it continuously develops new products, but it does not provide 3D software design services.

Production capacityThe supplier produces a broad range of valves and lists forging, cutting, drilling, and CNC facilities, together with standardized finished-product inspection instructions. Production-capacity support is weakened by the stated absence of a valid manufacturing-capacity contract with related subcontractors and the absence of in-stock capability.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. These capabilities are stated consistently across the technical-supplier and facility information.
