AI-Powered supplier vetting

SummaryThe supplier is a chemical-products and non-edible salt processor and seller with three production lines, including snow-melting-agent production and granulation equipment. It reports ISO9001:2015, ISO14001, and ISO45001:2018 certifications, structured finished-product inspection instructions, and stated pre-, in-, and post-production quality tracking. It offers sample-, design-, full-, minor-, and flexible-customization services, and reports OEM service for recognized brands. However, no SDK is available, only one R&D engineer is listed, and the service-management evidence is weak: no written procedures or records were provided for service assessment, corrective/preventive actions, or complaint handling. Production scale and quality staffing appear limited based on three lines and fewer than five quality-control staff. The supplier reports export activity mainly in East Asia and domestic markets, with lead times within 15 working days, but no Fortune 500 collaborations and no overseas service countries...

Supplier typeThe supplier operates in chemical products and non-edible salt processing and sales, with facilities for snow-melting-agent production, granulation, chloride-ion measurement, and pH measurement. It has three production lines and serves domestic and East Asian markets, indicating a manufacturing supplier focused on chemical and snow-melting-agent products.

CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 certifications, alongside a stated quality system with pre-production, in-production, and post-production tracking and quantitative testing. These records provide explicit evidence of management-system certification and formal quality-control practices.

After-Sales capabilityThe supplier reports accepted service quotation and payment terms, lead times within 15 working days in both peak and off-peak periods, and finished-product inspection instructions that are uniformly followed. However, it provides no written procedures or followed records for service assessment, corrective/preventive actions, or customer complaint handling, so formal after-sales capability is not sufficiently demonstrated.

Production capacityThe supplier reports three production lines, snow-melting-agent production and granulation facilities, inspection equipment, and uniformly followed finished-product inspection instructions. At the same time, fewer than five quality-control staff are listed; the evidence supports established production capability but not necessarily large-scale capacity.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and reports OEM service for recognized brands. These statements directly support broad customization and OEM capability.
