Best Inventory Rotation Method for Perishable Products: FIFO vs. FEFO vs. Lot-Specific Picking
Choose between FIFO, FEFO, and lot-specific picking using expiry, quality status, customer shelf-life rules, traceability, storage, and production requirements.The best inventory-rotation method depends on what makes a lot suitable for the next use. Receipt order is simple, but perishable and controlled products often require expiry, quality, customer, or production context.
1. FIFO: first in, first out
FIFO prioritizes the earliest received stock. It is useful when lots have similar shelf life and quality status, receipt sequence reflects age, and no customer-specific remaining-life rule changes the choice. It is easy to explain and operate, but it can pick the wrong lot when a newer receipt expires sooner.
2. FEFO: first expired, first out
FEFO prioritizes the earliest expiry or best-by date among eligible lots. It is usually the stronger starting method for shelf-life-sensitive inventory. It requires accurate lot-level dates and must exclude quarantined, rejected, recalled, reserved, or otherwise unsuitable stock.
3. Lot-specific or rule-based picking
Some orders and work orders need a particular supplier lot, country or certification status, allergen profile, color match, potency, customer approval, remaining shelf life, or test result. A rule-based method selects only eligible lots, then can apply FEFO within that group.
Five controls every method needs
- Capture lot and relevant date at receipt or production.
- Separate physical location from quality status.
- Define customer minimum remaining shelf life.
- Record the lot actually picked, not merely the suggested lot.
- Review overrides and near-expiry stock.
Example: Lot A arrived first and expires in 60 days. Lot B arrived later and expires in 25 days. FEFO suggests B, unless B is on hold or the customer requires 45 days remaining at delivery.
Batch Scale retains lot dates, locations, quality state, production consumption, and fulfillment history. Use the reorder-point calculator to prevent rotation discipline from being undermined by late replenishment.
No rotation rule makes an unsuitable product acceptable. Storage conditions, release status, customer requirements, and documented disposition remain authoritative.
