Never Stack Rejected Goods in GMP Primary Warehouses

Don’t Stack Rejected Goods in GMP Primary Warehouses

Remember: Rejected or non-conforming materials must be stored in dedicated quarantine areas — never mix them with approved inventory in primary storage zones.

Why This Matters in GMP

Rejected, expired, or non-conforming products must be physically segregated to prevent mix-ups and cross-contamination. Storing them in the main warehouse — even temporarily — risks their accidental issuance or usage. In GMP environments, such mix-ups can have serious consequences, including release of substandard products, deviation investigations, or regulatory action.

For example, if rejected tablets awaiting destruction are stored next to approved products due to space constraints, there is a real possibility that personnel may mistakenly dispatch or reprocess the wrong pallet — compromising product quality and traceability.

Regulatory and Compliance Implications

21 CFR Part 211.80 mandates that rejected materials be clearly identified and controlled under a quarantine system. EU GMP Chapter 5 requires segregated storage for rejected materials to prevent their unintended use. WHO GMP highlights the need for secure, labeled, and access-restricted areas for non-conforming goods.

Auditors examine warehouse zoning plans, material movement logs, and rejection protocols. Stacking rejected goods in active areas is considered a serious lapse in material control

and inventory assurance, often leading to major observations.

Implementation Best Practices

Designate separate, locked quarantine zones for rejected materials. Label rejected items clearly with tags or barcodes indicating status and intended disposition (e.g., return, destruction). Restrict access to authorized QA or warehouse personnel only.

Update warehouse SOPs to include segregation policies and audit trails for rejected goods. Integrate WMS (warehouse management systems) with rejection status controls to prevent unauthorized picking or dispatch. Conduct regular spot checks and ensure rejected items are removed promptly based on disposition decisions.
