AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier specializing in door lock hardware, with stated distribution across China and exports to multiple global regions. It reports ISO 9000 and ISO 9001 certification, 100,000-piece annual lock productivity, customization from samples and designs, minor customization, and full customization. Quality assurance and raw-material traceability are stated, but finished-product inspection is performed by packing staff, and corrective-action procedures lack written records. The supplier has no overseas showrooms, agents or branches, or offline trade-show participation. Innovation evidence is limited: it provides ODM services but reported no new products in the past year and no SDK. Financial credibility cannot be established because the provided financial records show zero figures for the stated periods; no financial figures are reproduced here.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and is described as a door lock hardware manufacturer/distributor with 16 years of craftsmanship, international service centers, and export coverage across numerous regions. Its stated product specialization and technical positioning support classification as a professional door-lock hardware supplier.

CertificationsThe supplier reports holding ISO 9000 and ISO 9001 certifications. These are explicit quality-management certification claims, although the provided slices do not include certificate numbers, validity dates, or issuing-body details.

Production capacityThe supplier states annual lock productivity of 100,000 pieces, a one-month average lead time in both peak and off-season, and proximity to Guangzhou/Shenzhen ports. It also reports quality assurance and raw-material traceability, but finished products are checked by packing staff and corrective/preventive procedures have no written records.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, minor customization, and full customization, and also provides ODM services. However, it does not provide 3D software design services, so the evidence supports broad physical/product customization rather than 3D design support.
