AI-Powered supplier vetting

SummaryThe supplier is a limited company with 399 employees and reported products covering aluminum and PVC windows and doors. It demonstrates broad customization, ODM capability, recent new-product activity, and OEM service for recognized brands. Production evidence includes stated annual capacity of 500,000 square meters for windows and 600,000 square meters for doors, supported by listed machinery and 15 quality inspectors. ISO9001:2015 certification is reported. Service procedures exist for corrective actions and complaints, but assessment records and formally approved supplier-list documentation are incomplete. The supplier has no overseas warehouse, showroom, agent, branch, or offline trade-show participation, and reports zero countries offering overseas services. Financial records are identified for 2021–2023, but no financial performance figures are provided. Customer-case evidence is limited to a general statement of OEM service for well-known brands.
