Don’t Place Raw Material Containers in Unclassified Areas Under GMP

Do Not Store Raw Material Containers in Unclassified Areas

Remember: GMP requires raw material containers to be stored only in designated classified or approved areas to avoid contamination and maintain material traceability.

Why This Matters in GMP

Raw materials form the foundation of pharmaceutical products. Improper storage of their containers—especially in unclassified areas—exposes them to dust, microbial contamination, temperature excursions, and unauthorized access. This not only threatens product quality but also disrupts traceability, inventory control, and audit readiness. GMP regulations emphasize strict environmental controls and segregation of materials based on status and risk. Allowing raw materials to sit in uncontrolled zones contradicts validated storage procedures and weakens the entire material control system.

Regulatory and Compliance Implications

FDA 21 CFR Part 211.80 & 211.142 require that materials be stored under appropriate environmental conditions with traceability. EU GMP Chapter 3 specifies that materials must be handled and stored to prevent contamination. WHO GMP and Schedule M mandate designated storage zones with proper classification and monitoring. Auditors review warehouse layouts, material movement logs, and temperature/humidity records. Storage in unclassified areas without justification is a direct GMP violation and often results in warning letters or batch quarantine.

Implementation Best

Practices

Clearly define and demarcate classified storage areas in warehouses and dispensing zones.
Use barcode or RFID systems to track material movement and prevent storage in unauthorized locations.
Train warehouse staff to follow storage maps and SOPs that define approved areas per material type.
Include regular internal audits to check for misplaced containers or environmental excursions.
Install surveillance systems and access controls to protect classified zones from unauthorized entry.
