AI-Powered supplier vetting

SummaryThe supplier operates in plastic, rubber, industrial textile, hardware, paper packaging, and printed packaging products, with licensed activities covering packaging printing and food-use packaging production. Its manufacturing plant covers 11,000.37 m² and includes printing, laminating, and bag-making equipment. The supplier supports broad customization and lists 20 qualified service-capable suppliers, with stated one-month lead times in both peak and off-seasons. However, service-management procedures, complaint-handling records, corrective-action procedures, and quality assurance are not documented; finished products are checked by packing staff, and only one quality assurance/control inspector is reported. The supplier has ISO9001:2015, ISO45001:2018, and ISO14001 certifications, but lacks overseas warehouses, showrooms, agents or branches, and reported participation in offline trade shows. Financial credibility, innovation capability, and customer-case evidence remain insufficiently established from...

Supplier typeThe supplier is a manufacturer and seller of plastic, rubber, industrial textile, paper, and printed packaging products. Its licensed scope specifically includes packaging printing, plastic packaging containers and food-use products, and food paper packaging, indicating a packaging-focused manufacturing supplier.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, covering quality, occupational health and safety, and environmental management. These certifications provide explicit evidence of formal management-system certification, although no conclusion is made about current validity beyond the stated information.

After-Sales capabilityThe supplier reports no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling, and states that quality assurance is absent. It also has no overseas warehouse, showroom, agent or branch; therefore, the available evidence indicates a documented after-sales and overseas-service deficiency.

This directly supports established packaging production capability, although quality inspection resources are limited to one reported inspector and packing-staff checks.
