AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier offering door and furniture hardware, with 3D design, ODM, OEM, sample-based, minor, and flexible customization services. It reports new products within the past year and operates two production lines with 6–10 quality-control staff, an annual output stated as 5,000,000 door-lock boxes, and a one-month off-peak lead time. Export activity is substantial, with Europe listed as the primary market and 90% of sales reportedly from exports. However, the evidence shows no valid manufacturing-capacity contract with associated subcontractors, no stock, overseas warehouse, or overseas showroom capability, and significant quality-system gaps: no quality assurance, no raw-material traceability, and no written complaint-handling records. Financial information is reported for 2021–2023, but no financial results are provided. No certification or customer-case evidence is supplied.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business and product scopes cover hardware products, door hardware, furniture hardware, furniture parts, household appliances, lighting, plastics, pneumatic and power tools, and related machinery.

After-Sales capabilityThe supplier reports no in-stock service, overseas warehouse, or overseas showroom capability. It also has no written procedures or records for handling customer complaints, although a corrective and preventive action procedure exists without written records.

R&D capabilityThe supplier is identified as a professional technical supplier, provides 3D software design, offers ODM services, and reports new products within the past year. It does not have an available SDK, but the available evidence supports active product-development and design capability.

Production capacityThe supplier operates polishing, drilling, punching, auto-assembly, and auto-installation equipment, with two production lines and 6–10 quality-control staff. It reports 5,000,000 door-lock boxes of annual output and a one-month off-peak lead time, but has no valid manufacturing-capacity contract with associated subcontractors and no stock capability.

Customization capabilityThe supplier explicitly offers customization from samples, minor customization, and flexible customization, alongside 3D software design, ODM, and OEM services for popular brands. These statements provide direct evidence of broad customization capability.
