Paperboard LC-GC-FID testing requires ethanol swelling, mCPBA epoxidation, and accurate UCM baseline integration to verify MOSH and MOAH migration compliance.

Validating paperboard claims requires cross-checking certificate scope codes on public databases and securing batch migration test reports.

Analytical testing verifies physical furnish markers and migration safety, while administrative chain records prove legal recycled content claims.

Verify hydrocarbon barrier integrity in recycled cartons through LC-GC-FID testing under EN 16995 with Tenax migration simulant to prove MOAH limits under 0.15 mg/kg.

Verify mass balance claims by auditing dry-fiber yield calculations, credit window expiry dates, and scope lines before printing claims on packaging.
