A supplier certificate must match the named legal entity, production site, scope and validity period. It is not a YuLink certificate.
Quality & supply process
Document the handoff before making the claim
Quality coordination starts with clear requirements and traceable evidence. The intended process is designed to surface unsupported claims and order inconsistencies before release.
This page describes YuLink's planned coordination method. It does not state that YuLink owns a factory, holds supplier certificates, conducts every inspection itself or guarantees a fixed inspection scope.
Six control points across the intended supply route
Each point identifies the evidence or agreement needed before the next handoff. The exact inspection and release scope remains order-specific.
Requirement review
Collect application, reference, quantity, packaging, destination and commercial context before identifying candidates.
Input gateSupplier document review
Review available entity, product, certificate and application documents. Supplier statements are not treated as independent facts without support.
Evidence gateSample & specification
Where appropriate, align the requested product, construction, dimensions, packaging and labels before production.
Approval gateChange control
Material, construction, packaging or production changes should be disclosed and reviewed before acceptance.
Change gateInspection coordination
Define inspection scope according to product, order and risk. No blanket third-party or 100% inspection statement is made.
Release gateShipment record alignment
Check product, quantity, packaging and shipment documents for consistency under the agreed terms before release.
Record gate
Four rules for public product information
These rules define how YuLink intends to separate supplier material from claims the company can responsibly publish.
A cross-reference identifies a candidate. Vehicle application still needs source and conflict review.
Materials, dimensions and performance data must map to the exact selected item and supporting evidence.
The inspection plan is agreed for the product and order risk rather than implied as a universal service.
