AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with 3D design, broad customization, ODM, and OEM capabilities. It reports production capacity for astragalus polysaccharide and in-stock service capability, while exporting under self-operated import/export rights. Its business scope covers food, health food, additives, veterinary and pharmaceutical activities, agricultural products, Chinese medicine extracts, and bio-based materials. Service procedures, complaint handling, and corrective-action records are documented. However, the evidence shows no available SDK, no overseas warehouse, showroom, agent, or branch, and zero quality-control test equipment reported. Quality assurance and traceability status are unknown. Financial information is represented only by reporting years, so financial credibility cannot be assessed.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business scope spans food and health food, additives, pharmaceutical and veterinary activities, agricultural products, Chinese medicine extracts, and bio-based materials, indicating a diversified manufacturing and related-services profile.

After-Sales capabilityThe supplier has a documented complaint-handling procedure with followed records, written service-capability assessment procedures, corrective and preventive action procedures, and in-stock service capability. However, it reports no overseas warehouse, showroom, agent, or branch, limiting demonstrated overseas support coverage.

R&D capabilityThe supplier reports professional R&D capability, 3D software design services, a new product within the past year, and ODM services. Three R&D engineers are listed, with responsibilities to provide solutions according to customer demand, but no SDK is available and no broader innovation metrics are provided.

Production capacityThe supplier reports annual productivity of 100 tons for astragalus polysaccharide and has in-stock service capability. Its stated scope includes production of food, health food, additives, pharmaceutical-related products, Chinese medicine extracts, and bio-based materials, although capacity evidence is specifically provided only for astragalus polysaccharide.

Customization capabilityThe supplier explicitly supports customization from samples and designs, full, minor, and flexible customization, as well as 3D software design, ODM, and customer-demand solution development. These records provide direct evidence of broad customization capability.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of branded-customer experience. No specific customer names, project details, product examples, or performance outcomes are provided, so the depth of these cases cannot be verified.
