AI-Powered supplier vetting

SummaryShijiazhuang New Aosuo Medical Equipment Co., Ltd. is a China-based limited company established in 2022 and identified as a trading company, with a stated business scope covering Class II medical-device sales, technical services, hardware and plastic products, and licensed Class II medical-device production. It reports ISO13485 and CE certification, CNC equipment, advanced technology, and mass-production capacity. The supplier has inventory capability, export licensing, and an average off-season lead time within 15 working days. Its strengths include sample-, design-, full-, minor-, and flexible-customization services. However, it does not provide 3D software design, ODM, SDK, or popular-brand OEM services; it reported no new product development in the past year and has zero quality-control test equipment recorded. Financial credibility, customer cases, and several quality and manufacturing-control details remain insufficiently documented.

Supplier typeThe supplier is identified as a trading company and limited company based in Hebei, China, established in 2022, with 13–14 employees and an affiliated company. Its stated scope includes Class II medical-device sales, technical consulting and services, hardware and plastic products, and licensed Class II medical-device production.

CertificationsThe company states that it has passed ISO13485 medical-device quality management system certification and CE certification. These are explicit certification claims relevant to medical-device quality management and product conformity, although the slices do not provide certificate numbers, validity dates, or certification scope.

R&D capabilityThe supplier is identified as a professional technical supplier and reports one R&D engineer, but it had no new products in the past year and does not provide ODM services, SDKs, or 3D software design. This indicates some technical and R&D involvement, but limited documented innovation output and digital development capability.

Production capacityThe company reports first-class CNC equipment, advanced technology, and mass-production capacity, and its business scope includes licensed Class II medical-device production. It also has inventory capability; however, the status of a valid manufacturing-capacity contract is unknown, and overseas warehousing is unavailable.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It does not provide 3D software design, so customization is supported but not through that specific digital design service.
