AI-Powered supplier vetting

SummarySuzhou Jinfeixin New Material Technology Co., Ltd. is identified as a professional packaging manufacturer and technical supplier established in 2010. It provides 3D software design and multiple customization options, has introduced new products within the past year, and provides OEM services for well-known brands. Quality processes include ISO9001:2015 certification, written inspection instructions, material traceability, complaint-handling procedures, and maintained quality records. However, its documented technical and quality resources are limited, with one R&D engineer, two quality inspectors, and no quality-control testing equipment reported. Production information indicates one production line and stated output of 200 million package bags. The supplier has no overseas warehouse, showroom, agent, or branch, but has participated in TOKYO PACK and exports mainly to East Asia.

Supplier typeThe supplier is explicitly described as a professional technical supplier and a professional packaging manufacturer specializing in air cushion packaging, thermal bags, courier bags, bubble mailers, and paper bags. Its stated establishment year is 2010, supporting an established operating history.

CertificationsThe supplier holds an ISO9001:2015 management-system certificate, which is explicitly reported in two slices. This provides documented evidence of a formal quality-management certification.

After-Sales capabilityOne technology engineer is responsible for confirming customer requirements and providing technical support for after-sales service. The supplier also reports clear, followed procedures for customer complaints, supplier corrective and preventive actions, and quality records, indicating structured support processes, although the dedicated technical team is small.

R&D capabilityThe supplier provides 3D software design, identifies as a professional technical supplier, and reports launching new products within the past year. However, it does not provide ODM services or an available SDK, and its documented R&D staffing consists of one engineer, so the evidence supports innovation capability but not broad independent development resources.

Production capacityProduction covers package bags using bag-making and blow-molding equipment, with one reported production line and stated output of 200 million package bags. The supplier reports order fulfillment within 15 workdays in both off-peak and peak seasons, but only two quality inspectors and fewer than five quality-control staff are documented.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. These options are reported consistently across the technical and production-related information, indicating broad product customization coverage.

Client casesThe supplier reports OEM service for well-known brands, exports 21%–30% of total sales, and serves East Asia, particularly Japan and South Korea. It has also participated in the TOKYO PACK offline trade show; however, no specific customer names, project descriptions, or verifiable case details are provided.
