AI-Powered supplier vetting

SummaryJiangsu Sunplas Co., Ltd. is identified as a privately owned manufacturer/factory in China, although another record classifies the company as a trading company. The supplier reports ISO 9001 and ISO 14001 certifications, quality inspections across raw materials, production, and finished products, and 6–10 quality-control staff. It reports five co-extrusion lines and annual plastic-sheet productivity of 18,000 tons; another company profile states eight lines and output above 30,000 tons, creating an unresolved capacity discrepancy. The supplier claims R&D capability, OEM/ODM services, functional plastic-sheet development, and after-sales support. Export activity is substantial, with 71%–90% of sales reportedly from exports and self-operated import/export rights. Named customers include Samsung, SHARP, HAIER, ELECTROLUX, Siemens, Benz, and SKYWORTH, but independent verification is not provided.

CertificationsThe supplier reports ISO 9001 and ISO 14001 management-system certifications and states that its products pass SGS and other inspection-institution certificates. These records provide explicit evidence of quality and environmental certification claims, although certificate numbers, validity dates, and scope are not supplied.

After-Sales capabilityThe supplier explicitly states that it has an experienced after-sale service department and a professional sales team. This supports the existence of after-sales capability, but no details are provided on service coverage, response times, warranty handling, or support personnel scale.

R&D capabilityThe supplier states that it can develop its own products and provide functional plastic sheets, with 6–10 years of total R&D-engineer experience reported. Its advanced co-extrusion production lines also support product-development capability, but no patents, laboratory resources, development projects, or measurable innovation outcomes are provided.

Production capacityThe supplier reports five production lines and annual plastic-sheet productivity of 18,000 tons, while another profile states eight advanced co-extrusion lines and output above 30,000 tons. Both records indicate established large-scale production, but the conflicting line and capacity figures prevent a precise capacity assessment.

Customization capabilityThe supplier explicitly offers OEM and ODM services and states that it can develop functional plastic sheets according to customer requirements. Its broad product range, including ABS, HIPS, PMMA/ABS, ASA/ABS, PVC, PP hollow, acrylic, and PC/ABS sheets, further supports product customization options.

Client casesThe supplier names Samsung, SHARP, HAIER, ELECTROLUX, Siemens, Benz, and SKYWORTH as representative customers and reports exports to France, the UK, Germany, the USA, and African countries. These are explicit claimed customer and market references, but the provided information does not include contracts, case studies, order details, or independent verification.
