AI-Powered supplier vetting

SummaryLingjie is a combined manufacturing supplier producing air-filtration products and cleanroom equipment, with five production lines, inventory capability, and stated delivery within 15 working days in both peak and off-peak periods. It reports broad customization and ODM services, recent new-product activity, quality assurance, and multiple certifications. However, documented service and quality records are incomplete, there is no valid manufacturing contract with related subcontractors, and no overseas agents, warehouses, showrooms, or offline trade-show participation. Export experience is stated as one year, while another slice identifies domestic markets as primary. Customer reach is reported at over 10,000 enterprises and institutions, but no specific customer cases are provided.

Supplier typeThe supplier is identified as a combined company and professionally manufactures Lingjie-brand coarse, medium, fine, and ultra-fine filters, along with air showers, pass boxes, clean benches, and FFUs. This supports classification as a combined manufacturing supplier rather than a purely trading or service entity.

CertificationsThe supplier states that it holds ISO9001, OHSAS18001, EU CE, RoHS, and other international certifications. These are explicit certifications relevant to quality, occupational safety, and product compliance, although the provided information does not include certificate validity dates or scopes.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and offers broad design customization. However, it has no available SDK and only three years of total R&D engineer experience are reported, so the evidence supports product-development activity but not a clearly strong technology platform.

Production capacityThe supplier operates five production lines, has inventory capability, reports delivery within 15 working days in both peak and off-peak seasons, and has six to ten quality-control staff. Capacity governance has weaknesses because no valid contract exists with related subcontractors and the order-fulfillment status is listed only as “6,” without an explained unit or benchmark.

Customization capabilityBoth R&D and design-service records list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also explicitly provides ODM services, giving clear evidence of broad customization capability.
