Verification Procedures for Chain of Custody Input Allocation Ledgers
Verify chain of custody allocation ledgers by reconciling raw fiber dry mass, mill yield factors, and timestamped credit balances against outbound invoices.
Fiber Traceability
Origin Verification
Supply chain tracking systems are designed to verify that wood fibres used in papermaking originate from legally and sustainably managed forests. Implementing fiber traceability allows mills to document the journey of timber from the forest floor to the final roll of paperboard. This verification prevents the entry of wood from controversial sources into the manufacturing stream.
It supports the credibility of environmental certification schemes that print buyers rely on to satisfy consumer expectations.
Chain Mechanics
Paper mills use two main approaches to track the origins of their wood pulp. The physical segregation method keeps certified fibres completely separate from uncertified materials throughout the production process. When this is not practical, the mass balance method calculates the proportions of certified pulp entering the mill and applies those ratios to the finished paperboard outputs.
This accounting ensures that the certified volume sold corresponds to the certified volume purchased.
Market Compliance
Strict enforcement of raw material tracking is required to comply with international timber regulations such as the European Union Deforestation Regulation. Companies that cannot prove the origin of their materials face severe penalties and may be barred from major markets. This compliance protects brands from reputational risks associated with deforestation.
