Procurement Recommendations & Compliance Notes
If you are still evaluating whether to require GRS certification or Transaction Certificates (TCs) from your suppliers, first check whether your brand customers already require their supply chains to submit a GRS Scope Certificate (SC). This will influence the priority of your material sourcing.
