Verifying Mass Balance Recycled Content Claims in Packaging Logistics Files
Verifying mass balance recycled content in packaging requires auditing weighbridge logs, process yields, scope certificates, and credit ledgers across logistics files.
Scope Certificate Scope
Audited Boundary
Credential documentation defines the certified processing operations, product categories and facility locations covered by a chain of custody certificate. Environmental auditing bodies define the scope certificate scope to establish the exact operational boundary authorized to process certified raw materials. Documentation lists all approved facility sites, subcontracted processing units and eligible product lines within the certified corporate entity.
Certified claims apply exclusively to activities and products explicitly listed within this administrative framework. Coverage ceases immediately if a manufacturing site alters certified processes without auditor approval.
Site Authorization
System certification requires rigorous initial and annual on-site audits of every facility included on the scope certificate document. Auditors verify that listed sites maintain physical segregation procedures, mass balance tracking software and competent personnel to handle certified paperboard. Subcontractors performing slitting, printing or laminating operations must be formally inspected and listed as verified processing sites under the main certificate holder.
Scope expansion requests require physical audit inspection before new facilities or product categories can be added to the official scope ledger. Non-conformances identified during surveillance audits can result in scope restriction or suspension of the entire certificate. Certified organizations must maintain updated product registers showing compliant raw material inputs for every certified output product.
Process Coverage
Documented boundaries specify allowable processing activities, including pulp blending, paper manufacturing, converting and commercial distribution. Validating the scope certificate scope ensures that outgoing product claims reflect independently verified operations at all listed production sites.
