AI-Powered supplier vetting

SummaryThe supplier is a limited company and a professional technical supplier focused on plastic-product and plastic-pipe machinery, including drip-irrigation tape and pipe-making equipment. It provides 3D design, OEM, ODM, and multiple customization options, but reports no new products in the past year and no available SDK. Manufacturing evidence shows one production line, 21–30 quality-control staff, in-stock capability, and no valid manufacturing-capacity contract with affiliated subcontractors. Export experience is reported at eight years, with 41%–50% of sales from exports and Southeast Asia/Middle East among its export markets. However, it has no overseas agents or branches, warehouse, showroom, or stated overseas service countries. Management-system certification is listed as NIL, and the supplier lacks a factory environmental impact assessment report. Financial data is represented by years rather than substantive performance values, so financial credibility cannot be determined.

Supplier typeThe supplier identifies itself as a professional technical supplier and a limited company. Its stated business scope covers plastic-product manufacturing and sales, machinery and special-equipment manufacturing, and import/export activities; its listed products are primarily plastic pipe and drip-irrigation machinery.

CertificationsSupplier management-system certification is explicitly listed as NIL. This indicates no reported certification under the provided field, although no specific certification standard or requirement is stated for comparison.

After-Sales capabilityThe supplier has in-stock service capability and can quote under FOB, CIF, CFR, and EXW terms, with Qingdao Port identified as the nearest port. However, it reports no overseas warehouse, showroom, agents or branches, and zero countries where overseas services are offered, limiting evidence of established overseas after-sales coverage.

Production capacityThe supplier lists multiple machinery products and reports in-stock capability, one production line, and 21–30 quality-control staff. However, it also reports no valid contract covering manufacturing capacity with its factory and related subcontractors, creating a documented capacity-governance deficiency.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its 3D design capability and ODM service further support the ability to provide customized product or design solutions.
