AI-Powered supplier vetting
SummaryThe supplier is identified as a combined company specializing in standard and non-standard fasteners, washers, springs, stamping parts, spring lock pins, and related products. It holds ISO 9001 certification, operates three production lines, and reports quality assurance, standardized finished-product inspection instructions, and inventory capability. Customization and OEM/ODM services are available, including customization from samples and designs. However, the evidence shows no written complaint-handling or corrective/preventive-action procedures, no valid manufacturing contract with related subcontractors, no overseas agents, branches, warehouse, showroom, or trade-show participation, and no new products developed in the past year. Export experience is stated as five years, with exports representing 21%–30% of sales.
CertificationsThe supplier reports holding ISO 9001 certification. This is explicit evidence of a recognized quality-management-system certification and supports a positive assessment for certification holding.
After-Sales capabilityThe supplier has inventory capability and accepts FOB, CIF, CFR, and EXW quotation terms, but it has no written procedures or records for corrective/preventive actions or customer complaints. It also lacks overseas agents or branches, overseas warehouses, and showrooms, indicating a documented weakness in structured after-sales support.
R&D capabilityThe supplier provides ODM services and has broad design customization capability, but it reports no available SDK, no new products during the past year, and fewer than five years of total R&D engineer experience. The evidence demonstrates some development-service availability but also an explicit recent-product-development deficiency.
Production capacityThe supplier operates three production lines, reports inventory capability, uses uniformly followed finished-product inspection instructions, and produces multiple categories of standard and non-standard fasteners and spring-related components. However, it has no valid contract with related subcontractors, creating a documented manufacturing-governance weakness despite its stated production resources.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and also provides OEM and ODM services. Its company description further states that it produces non-standard fasteners and components, providing direct support for strong customization capability.
