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.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate. Product compliance certification and raw-material quality reports are listed only as “Others,” without specific standards or certificate details.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints. However, it has no overseas warehouse, showroom, agent, branch, or overseas-service country coverage, which limits demonstrated overseas service reach.

R&D capabilityThe supplier reports new products during the past year and provides ODM services, indicating active design and development capability. However, it has no available SDK, so software-development support is not demonstrated.

Its stated product scope covers aluminum and PVC windows and doors, supporting substantial manufacturing capability.
