SummaryThe supplier is identified as a professional technical supplier offering 3D software design, broad customization, ODM, and OEM services. It holds ISO9001:2015 and ISO14001:2015 certifications, has two years of total R&D engineer experience stated, and reports new-product development during the past year. Service-capability controls include written assessment procedures, records, an approved-supplier list, and corrective/preventive-action procedures, although the update timing of the list is incomplete. Export capability is supported by self-operated import/export rights and six years of export experience. The supplier reports no in-stock capacity, overseas warehouse, overseas showroom, or valid manufacturing-capacity contract with related subcontractors. ERP-based digital management is established, while evidence for financial strength, customer cases, and some sustainability systems is insufficient.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and lists technology services, industrial design, industrial engineering design, research and development, and equipment-related activities in its business scope. This supports classification as a technical and engineering-oriented supplier rather than only a trading company.
