AI-Powered supplier vetting

SummaryHOMI is identified as a Guangzhou-based trading company offering aluminum profiles, windows, and doors for residential and commercial applications. It reports ISO 9001 and ISO 14001 certification, ODM/OEM experience, broad customization options, substantial export activity, and stated production volumes. However, it lacks overseas showrooms, agents, or branches; provides no 3D design or SDK; reported no new products in the past year; and has no documented procedures for service assessment, complaints, corrective actions, or quality assurance. Its customer-case evidence is limited to general application sectors and claims of serving popular brands without named references.

CertificationsThe supplier reports holding ISO 9001 and ISO 14001 certifications. These are explicit certifications related to quality and environmental management systems, supporting a positive assessment for this field.

After-Sales capabilityThe supplier has no overseas showroom, agent, or branch, and reports no written procedures or records for service assessment, complaints, or corrective and preventive actions. Although it accepts several service quotation and payment terms and states a one-month average lead time, the documented after-sales management infrastructure is insufficient.

R&D capabilityThe supplier provides ODM services and reports total R&D engineer experience of 6–10 years. However, it does not provide 3D software design or an SDK and reports no new products during the past year, creating an explicit limitation in recent product innovation and digital design support.

Production capacityThe supplier reports aluminum profile output of 5,000 tons and aluminum window and door output of 100,000 square meters, with one-month lead times in both peak and off-season periods. It also states that finished products are checked by packing staff, but this inspection method is limited and does not establish comprehensive production quality assurance.

Customization capabilityThe supplier explicitly offers flexible, minor, and full customization, including customization from designs and samples, and also provides ODM and OEM services for popular brands. These multiple stated customization modes demonstrate broad customization capability.
