Chain Accounting
Chain of custody accounting frameworks track sustainable fiber volumes moving through pulp and paper converting facilities without requiring physical segregation. Certified input quantities are matched mathematically against output products across a defined operational accounting period. Mass balance reconciliation verifies that the volume of certified packaging material claimed and sold equals the certified fiber volume purchased and processed.
The accounting methodology stops at claims exceeding physical intake ratios and does not guarantee physical fiber presence in an individual package.
Volume Tracking
Pulp and paper manufacturing processes merge certified and non-certified fiber streams during stock preparation to maintain machine efficiency. Facility accounting systems record incoming certified tonnages and apply processing yield factors to determine available claim credits. Conversion losses and scrap generation are deducted from total certified credits before allocating claims to outgoing finished goods.
Unused credits carry forward into subsequent accounting periods according to system boundaries set by standards bodies.
Audit Compliance
Third-party certification audits evaluate mill production logs and sales invoices to verify mathematical accuracy. Discrepancies between physical input ratios and claimed credit allocations require immediate reconciliation to prevent false environmental marketing claims. Automated enterprise resource planning software tracks volume credits across complex multi-site manufacturing networks.
Over-allocation of certified claims triggers corrective action requests and potential suspension of chain of custody credentials. Systematic credit balancing maintains market integrity across global paperboard supply chains. Audit schedules require complete verification before volume claims transfer downstream.
