AI-Powered supplier vetting

SummaryThe supplier is a chemical manufacturer and seller focused on sodium hydrosulfide and sodium sulfide, with additional logistics and general goods sales activities. It reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, raw-material traceability, documented corrective-action and complaint-handling procedures, and inventory capability. Production-related evidence includes a sodium hydrosulfide production line, stated stable product quality, and one-month average lead times in both peak and off-season periods. However, the supplier is not identified as a professional technical supplier, does not provide 3D software design or SDK services, lacks a valid manufacturing-capacity contract with related subcontractors, and has no overseas warehouse, showroom, agent, branch, or offline trade-show record. Financial information is insufficient for a credibility judgment, and no specific customer names or verifiable customer cases are provided.

Supplier typeThe supplier is explicitly described as not being a professional technical supplier and operates primarily in the production and sale of sodium hydrosulfide and sodium sulfide, with related transportation and trading activities. The identified combined facility is a sodium hydrosulfide production line, indicating a chemical manufacturing profile rather than a technical-service profile.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These stated certifications provide explicit evidence of quality, occupational health and safety, and environmental management systems.

After-Sales capabilityThe supplier has a documented customer-complaint handling procedure with followed records, inventory capability, defined payment and quotation terms, and stated one-month average lead times. However, it has no overseas warehouse, showroom, agent, branch, or overseas-service coverage, so the available evidence supports basic service processes but not broad overseas after-sales support.

R&D capabilityThe supplier does not provide 3D software design services, has no available SDK, and is not identified as a professional technical supplier. It also reports no AI model for big-data decision support and no CRM or SAP sustainable-development capability, which does not support a strong innovation assessment.

Production capacityThe supplier lists production and sales of sodium hydrosulfide and sodium sulfide, identifies a sodium hydrosulfide production line, maintains inventory capability, reports one-month average lead times in both peak and off-season, and has raw-material traceability. These indicators support established production capability, although the absence of a valid manufacturing-capacity contract with related subcontractors is a documented limitation.

Customization capabilityThe supplier lists customization from samples, designs, full customization, minor customization, and flexible customization. This is explicit evidence of a broad stated customization offering, although no examples or technical details of customized chemical products are provided.
