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.
Controlled Wood Eligibility
Sourcing Qualification
Chain of custody risk mitigation systems define which uncertified virgin fibers may enter mixed paper manufacturing batches. Requirements for controlled wood eligibility restrict pulpwood harvesting to sources free from illegal logging, civil rights violations, genetically modified trees, and high conservation value conversion. Mill procurement teams must execute formal risk assessments for every uncertified forest supply district.
Fiber originating from areas with unmitigated sourcing risks cannot enter certified manufacturing streams.
Risk Assessment
Procurement personnel evaluate timber origin data using published risk registries and local forest governance reports. High-risk supply zones require field verification audits and origin tracking documentation before wood receipts obtain approval. Suppliers in these regions must present valid harvest permits and transport dockets before entering supply networks.
Independent auditors verify district origin declarations annually to confirm harvest legitimacy. Mixed pulp production requires strict segregation of compliant logs from unverified timber stocks in the woodyard.
Output Limitation
Qualifying virgin fiber under these rules allows mills to mix uncertified wood with certified stocks to produce percentage-based forest management claims. Uncertified material that fails to meet these baseline criteria causes the entire production batch to lose certification status. The eligibility status remains valid only while district risk evaluations undergo annual updates.
