SummaryThe supplier is identified as a professional technical supplier with R&D capability and broad customization services, but it does not provide 3D software design or SDK services. Its stated business scope covers feed additives, pesticides, veterinary drugs, Class I medical devices, and non-hazardous chemical products and raw materials. Evidence shows inventory capability, documented finished-product inspection procedures, and written procedures for assessing service capability.

Supplier typeThe supplier is explicitly classified as a professional technical supplier with R&D capability. Its stated scope includes feed additives, pesticides, veterinary drugs, Class I medical devices, and chemical products and raw materials, subject to applicable approvals and exclusions.

After-Sales capabilityThe supplier has inventory capability and written procedures with follow-up records for assessing service capability. However, it lacks written procedures or records for corrective/preventive actions and customer complaint handling, and it reports no overseas warehouse, showroom, agent, or branch.

R&D capabilityThe supplier is identified as having professional R&D capability, with nine years of total R&D-engineer experience and stated emphasis on technological innovation and green bio-manufacturing. It does not provide 3D software design or SDK services, which limits the demonstrated scope of its innovation-support capabilities.

Production capacityThe supplier’s business scope includes production and operation of veterinary drugs subject to approval, and it has inventory capability and uniformly followed finished-product inspection instructions. However, no valid contract exists between the factory and its related subcontractor, creating a documented gap in manufacturing-capacity arrangements.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, flexible customization, and minor customization. This provides direct evidence of a broad range of customization services, although 3D software design is not available.
