Chain of Custody Credit Allocation Ledger Audit Procedures
Verify credit allocation ledgers by auditing dock scale moisture corrections, empirical conversion yield factors, and the rolling 24-month expiration limit.
Supplier Certificate Scope
Scope Boundary
Certification limits for a certified supplier define the specific products and processes that are covered by an official sustainability certificate. Checking the supplier certificate scope is a necessary step for any buyer who needs to ensure that the material they are purchasing is truly certified. This document lists the categories of wood products and the specific locations that are authorized to sell certified goods.
Verification Detail
A buyer must verify that the specific product description on the invoice matches one of the categories listed in the supplier’s scope. If a mill is certified to produce kraft paper but the invoice is for a different grade of board not mentioned in the scope, the claim is invalid. The scope also indicates which chain of custody system is being used, such as the credit or percentage system.
This information is available on public databases and should be checked regularly to account for any changes or expirations. Relying on an outdated or irrelevant scope can lead to a failure in the buyer’s own certification audit.
Risk Reduction
Confirming the scope protects the supply chain from the inclusion of unverified or non compliant materials. It ensures that the environmental claims passed on to the final consumer are based on a valid certification.
