Executive summary

Transaction Certificates support certified material claims by connecting products, quantities and shipments to an approved chain-of-custody system.

A TC is typically requested when certified goods are sold and the buyer needs evidence that the goods are covered by a valid scope certificate and supporting traceability records.

Required evidence

Certification

Valid scope certificate and product scope.

Commercial records

Purchase order, invoice, packing list and shipment details.

Traceability

Upstream certificates, material composition and production records.

Common mistakes

Good practice

Build a shipment file before dispatch and check consistency across commercial and certification documents before application.
