PEFC ST 2002

Chain Definition

Supply chain governance defines pefc st 2002 as the normative standard controlling custody transfer across converting plants and paper mills. Forest certification depends on this framework to track certified fibre through every pulp digester, sheet former, and finishing line without loss of identity. Certified material segregation stops at the final point of sale to end consumers or when uncertified furnish enters the batch mixing tanks above permitted threshold limits.

Auditing bodies check mass balance calculations against mill input records to verify compliance across paper grades.

Transfer Protocol

Documented control procedures govern how converting facilities handle certified paperboard reels during slitting and sheeting operations. Production planners apply percentage methods or physical separation models to maintain batch integrity while substrate moves through printing presses and die cutters. Verification records track incoming delivery volumes against outgoing finished carton weights so auditors can reconcile material losses incurred during trimming.

Stock management software flags discrepancies whenever uncertified pulp enters production runs destined for labeled packaging.

Market Compliance

Brand owners demand verified chain documentation to satisfy procurement mandates set by retailers purchasing folding cartons and corrugated containers. Printing plants maintain accredited status through annual surveillance audits inspecting warehouse segregation and invoice matching protocols. Regulatory scrutiny penalizes fraudulent fiber claims across consumer goods packaging, forcing converters to separate certified production runs from standard stock entirely.

Commercial agreements require paper mills to provide valid certificate numbers on dispatch documentation before delivery trucks leave the loading dock.
