Procurement transparency and evidence

Before you confirm an order

1. Confirm the complete manufacturer part number, suffix, package and temperature grade.
2. Confirm quantity, condition, date code and lot requirements; request batch-specific photographs.
3. Agree on source documents and the inspection method, sample size and acceptance criteria.
4. Confirm availability, lead time, quotation validity, currency and shipping terms in writing.
5. Evaluate alternatives against the manufacturer datasheet; engineering approval is required before substitution.
6. Keep the quotation, order, labels and inspection records together for receiving checks.

Documents for your specific batch

For a sourcing review, request the available source records, batch label photographs and inspection documents. Check the issuer, scope, lot reference and date of each record, and match them to the parts being supplied. Use catalogue images for identification and batch photographs for receiving checks.

Confirm availability, origin, minimum order quantity and delivery dates against the quotation and supporting documents. Check the issuer and scope of any authorization or certificate relevant to the order.

Receiving checks & issue handling

Compare the delivery with the agreed part number, quantity, packaging and inspection criteria. If something differs, retain the packaging and labels and contact us with the order reference, photographs and any test findings. Return, replacement and refund arrangements are subject to the written terms agreed for the order.

Content and source policy

Product guides provide sourcing information, not a substitute for the current manufacturer datasheet or application validation. Original specifications retain their model and unit. Company activities and reference illustrations are distinguished from batch-specific evidence. Send corrections with the page URL and supporting documentation.
