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.
Audit Surveillance
Verification Period
Systematic periodic monitoring forms the verification mechanism that maintains valid certification across multi-year chain of custody cycles. The process of audit surveillance requires accredited certification bodies to inspect paper mills and converting plants between main re-assessment dates. These interim evaluations verify ongoing adherence to wood sourcing standards and input-output balance accounting rules.
Standard certification cycles span five years, requiring annual surveillance checks to prevent administrative drift or unapproved material mixing.
Assurance Protocol
Field auditors examine physical inventory records, mass balance ledger sheets, trademark usage logs, and supplier verification documents during an on-site visit. Sampling methods allow inspectors to trace specific batches of certified paperboard back to forest harvest certificates or post-consumer waste invoices. Non-conformities identified during these mid-term evaluations trigger corrective actions that facility managers must resolve within specified time limits.
Failure to address major non-conformities leads to immediate certificate suspension, halting certified sales claims across affected product lines.
Scope Limit
The monitoring process covers internal control procedures, mass balance calculations, mass loss conversions, and physical material handling at certified sites. Out-of-scope activities include raw material purchasing decisions made by uncertified parent entities or third-party transport vendors. Verification applies strictly to facilities listed on the active certificate register.
