Check certificate identity, scope and current status

Request a readable certificate showing the legal entity, manufacturing address, certificate number, issuing body, scope and validity dates. Compare these details with the site supplying your order.

Use the issuing body’s verification channel to check the document and current status. Ask the supplier to explain any different company names, additional sites or activities outside the stated scope.

List the customer-specific product tests and shipment documents separately in the purchase order. Confirm which records will be supplied for your selected part and batch, and when they will be available.

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.
