Origin, manufacturing source, available lot, packaging, minimum quantity and lead time are confirmed against the actual project.
Written supply basisTest methods, acceptance limits and the required representative or commercial-lot documents are agreed before order.
Reviewable evidencePackaging, destination, Incoterm and document requirements are confirmed before shipment so buyers can review the delivery plan.
Shipment plan confirmedRepresentative samples, pilot quantities and third-party testing scope are discussed before commercial-lot qualification.
