Tie inspection evidence to the shipped batch

Agree the inspection plan before production, including critical dimensions, visual criteria, material records, sampling method and any functional tests. State who approves deviations.

Request reports carrying the part number, drawing revision, batch identifier, inspection date and measured results. Confirm how carton labels and packing lists connect the delivered parts to those records.

Define the process for quarantine, investigation and replacement when a shipment fails the agreed criteria. Keep an approved sample and the applicable specification for subsequent batch comparisons.

Certification, parameters and delivery

Ask for current certificates relevant to the manufacturing site and your purchasing requirements. Verify the document number, scope and validity. Match inspection records to the part and lot specified in your order.

State the dimensions, compound requirements and operating conditions you need confirmed. Request separate sample and production schedules, including the approval trigger, dispatch date and destination. VKEFOT certification availability, MOQ and delivery dates must be confirmed in the quotation for your selected part.
