Never Ignore Expiry Dates Even if Materials Look Intact

Do Not Rely on Appearance to Validate Material Expiry

Remember: Under GMP, material expiration must be strictly enforced—appearance cannot replace expiry date as a quality control parameter.

Why This Matters in GMP

Pharmaceutical raw materials, packaging components, and reagents are assigned expiry dates based on validated stability studies. Even if a material looks, smells, or feels acceptable, its chemical potency or microbial limits may have deteriorated past the labeled date. Using expired materials—despite apparent visual integrity—violates GMP principles and can result in compromised product quality or safety. Visual inspection alone cannot confirm degradation, microbial contamination, or other critical attributes that may affect formulation, packaging, or analysis outcomes.

Regulatory and Compliance Implications

FDA 21 CFR Part 211.84 requires that components be tested and approved before use and must not exceed expiry limits. EU GMP Chapter 5 dictates that expired materials be clearly segregated and not used in manufacturing. WHO GMP requires expiry-based inventory control to ensure the use of qualified materials only. Schedule M warns against reliance on physical appearance and mandates expiry verification in dispensing, formulation, and sampling areas. Inspectors expect robust systems to prevent expired stock usage, including barcode controls, bin card updates, and

QA monitoring.

Implementation Best Practices

Label all materials with clear expiry dates and rotate stock using FIFO (First-In, First-Out) or FEFO (First-Expiry, First-Out) principles.
Use warehouse management systems with auto-alerts for upcoming or expired lots.
Train personnel to check and record expiry dates before each transaction (sampling, dispensing, production).
Implement bin card systems and electronic tracking with lockouts for expired material usage.
Ensure QA reviews include expired material logs and discard records with documented reasons.
