Concept explicatif généré par l'IA ; il ne s'agit ni d'une photographie de produit de Litian Yunde ni d'un design validé.
When a customer supplies hardware for a carbon fiber assembly, record exactly what is handed over, what the supplier is expected to do with it and how unused or unsuitable items are handled. Hardware ownership alone does not define inspection, storage, assembly, loss reporting or replacement responsibility.
Use an identifiable handover list
List each screw, insert, latch, seal or bracket with its controlled reference and quantity. Include any required documentation or approved sample. Separate left/right parts and versions that look similar. Record receipt condition and discrepancies before consuming the items in an assembly. A box described as customer fittings is too ambiguous when several component variants share the same general appearance.
Agree what the supplier checks
Clarify whether incoming hardware is counted only, inspected against stated requirements, or assessed for compatibility with the composite component. State who owns the design decision if the supplied item conflicts with the drawing. Do not assume that assembling a supplied fastener certifies its material, finish or performance. If a substitution becomes necessary, approve and document it before use rather than replacing it informally.
Account for use, findings and leftovers
Record the quantity used, held, rejected, consumed in agreed trials and returned. Include how additional items are requested when the supplied quantity is insufficient. If an assembly operation can damage a hardware item, discuss the expected allowance and reporting process beforehand. Keep the relationship between hardware identity and delivered assembly where traceability is required. Return arrangements should be part of the agreed supplied scope.

Example: two latch versions in one shipment
A customer sends visually similar latches with different mounting patterns. The supplier records them as separate references and finds that one does not match the approved shell. That quantity is held pending clarification. The assembly record identifies the accepted latch reference, and the unused items remain accounted for rather than disappearing into a general stock drawer.
Scénario à titre d'exemple ; il ne s'agit ni d'un cas client ni d'un résultat de production avéré.

Questions posées par les acheteurs
Does customer ownership remove the need for incoming records?
No. The supplied items still need identifiable custody and an agreed handling scope.
Can the supplier replace a fitting with an equivalent-looking item?
The substitution must follow the agreed approval route; visual similarity is insufficient.
