AI-Powered supplier vetting

SummaryThe supplier is presented as a professional technical HVAC/R supplier with production lines, moulds, patents, and a complete HVAC/R product range. It reports ISO 9000 and ISO 9001 management-system certifications and states that most products hold CE, RoHS, and UL approvals. Customization is available from samples and designs, including full, minor, and flexible customization. However, the supplier does not provide 3D software design, ODM, SDK, or well-known-brand OEM services, and launched no new products in the past year. It has no overseas warehouse, showroom, agent or branch, and has not participated in offline trade shows. Service quality assurance is stated, but complaint handling and corrective-action arrangements are described only as “Others.” Financial records are referenced for 2022–2024, but no financial performance details are provided. No specific customer cases are identified.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and describes a complete HVAC/R range with production lines, moulds, patents, and one-stop solutions.
