AI-Powered supplier vetting

SummaryChoice Chemicals Ltd. is a privately owned manufacturer/factory in Hunan, China, with 16 employees and stated production capacities for several sodium and magnesium sulfate products. It offers customization, ODM, and OEM services, and reports new-product development during the past year. The supplier has written procedures and records for service assessment, corrective/preventive actions, and complaint handling. ISO 9001:2015 certification is reported. Financial records are identified for 2021–2023, but no financial results are provided. The supplier lacks 3D software design, SDK, overseas warehouse, overseas showroom, and overseas agent or branch capabilities. No specific customer names or verifiable customer cases are provided.

Supplier typeThe supplier is identified as a Manufacturer/Factory and a private limited company in Hunan, China. Its stated business scope includes chemical product offerings together with import/export, equipment sales, information technology consulting, and technical services.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate. No other certification details, scope, issuing body, or validity information are provided.

After-Sales capabilityThe supplier has written procedures and followed records for service-capability assessment, corrective and preventive actions, and customer complaint handling. However, it has no overseas warehouse, showroom, agent, or branch, which limits documented overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year and provides ODM and OEM services. Conversely, it is explicitly not a professional technical supplier, does not provide 3D software design services, and has no available SDK; therefore, innovation evidence is present but technically limited.

Production capacityThe supplier is identified as a factory and reports annual capacities of 200,000 tons of sodium metabisulphite, 50,000 tons of sodium bisulphite, 50,000 tons of sodium sulphate, and 80,000 tons of magnesium sulfate heptahydrate. These stated capacities provide explicit evidence of substantial production capability.

Customization capabilityThe supplier states that it can customize from samples and designs, provide full, minor, and flexible customization, and offer ODM and OEM services. It does not provide 3D software design services, so customization is supported but not through that specific design tool capability.
