Clearance of imported food packaging requires matching exact batch lot numbers across invoices, declarations of conformity, and ISO 17025 accredited migration test reports.
Screening Mechanics for Unknown Volatile Migrants in Packaging
Screening unknown volatile migrants demands thermal liberation, high-resolution spectral deconvolution, worst-case mass balance, and toxicological hazard assignment against threshold limits.
Polyolefin Oligomer Screening in Food Contact Polymers
Polyolefin oligomer screening requires coupled LC-GC-FID quantification of POSH and POAH fractions below ten parts per billion using matched food simulants.
Accredited Test Reports Replaced by an in House Result
Replacing accredited test reports with internal results is legally permitted but shifts the entire evidentiary burden, requiring full raw data, instrument validation, and traceable calibration to survive regulatory audits.
