AI-Powered supplier vetting

SummaryFoshan Shunde Topcod Industry Co., Ltd. is identified as a Chinese manufacturer of desiccants, humidity indicator cards, aluminum foil bags, and related packaging materials. The supplier reports an ISO9001:2015 certificate, more than 10 production lines, 101 employees, a 11,000 m² manufacturing plant, and stated annual capacities of 9,000 tons of desiccant and 3,000 tons of aluminum foil bags. Its descriptions also reference professional technical staff, testing equipment, and compliance with several product standards. Export activity is documented, with 41%–50% of sales from exports and exporting beginning in 2016. Evidence supports production scale, certification, and international customer experience, but is insufficient to confirm financial strength, customized-production capability, or the scope and reliability of after-sales services.

Supplier typeThe supplier is explicitly classified as a manufacturer in China, while another record describes the company nature as a trading company. Its stated products and manufacturing plant support manufacturing activity, but the conflicting classification means the business profile is not completely consistent.

CertificationsThe supplier explicitly reports an ISO9001:2015 certificate. It also states that its products meet or passed MIL-D-346E, DIN55473, SGS, and RoHS-related requirements, although the slices do not provide independent verification or certificate details for each claim.

R&D capabilityThe supplier claims advanced production lines, specialized machinery for humidity indicator cards and moisture-proof bags, a professional technical team, four R&D engineers, and ongoing product and quality development. These details provide positive evidence of technical and development capability, although no specific proprietary innovations or R&D achievements are documented.

Production capacityProduction capability is supported by 101 employees, an 11,000 m² manufacturing plant, more than 10 production lines, and stated capacities of 9,000 tons of desiccant and 3,000 tons of aluminum foil bags annually. The supplier also reports mechanized production lines and testing equipment, indicating substantial manufacturing infrastructure.

Client casesThe supplier states that Honda, Panasonic, Sony, and other well-known companies cooperate with it, and that its products are sold worldwide with good feedback. These are supplier-reported customer references; the slices do not include order details, verification, or named case studies.
