FEFO (First Expired, First Out)
FEFO is a stock rotation rule under which the batch with the earliest expiry date is issued first, regardless of when it was received. It differs from first-in-first-out, which orders issues by receipt date, and the two diverge whenever a later delivery carries a shorter remaining shelf life. FEFO is the appropriate rule wherever goods expire, because receipt order does not predict expiry order.
What Is FEFO (First Expired, First Out)?
Rotating stock by receipt date is the intuitive rule and it fails wherever goods expire, because the order in which deliveries arrive tells you nothing about the order in which they will become unsaleable. A consignment received this week can carry a shorter remaining life than one received two months ago, depending on when each was manufactured and how long it sat in the supply chain before reaching you.
Issuing by expiry rather than by receipt closes that gap, and it is the appropriate discipline for pharmaceuticals, food, agricultural inputs and anything else with a dated life. Applying it requires the expiry date to be captured at receipt and held against the stock at location level, since a rule nobody can execute at the shelf is a policy rather than a control. Where a system holds only receipt dates, the picker has no way to comply, and the first evidence of the failure is usually a quantity of expired goods discovered behind newer stock at a count.
Which Sectors Use FEFO (First Expired, First Out) and Why
It governs any material carrying a dated life, since the sequence goods arrive in tells you nothing about the sequence they will pass out of use.
- Pharmaceutical manufacturing and distribution, where issuing out of date sequence has consequences well beyond a write-off.
- Food processing and grocery retail, particularly in chilled and fresh categories where the usable window is days.
- Agricultural inputs, where crop protection products and treated seed both carry defined lives.
- Cosmetics and personal care, subject to shelf life and to labelling requirements around it.
- Specialty chemicals and adhesives, where properties degrade on a schedule.
- It is unnecessary in engineering components, metals and most durables, where receipt order is a perfectly adequate rotation rule because nothing expires.
How FEFO (First Expired, First Out) Works in Practice
- Expiry is captured at goods receipt, read from the carton rather than assumed from the delivery date, and held against the specific batch.
- The batch and its date are recorded against the storage position, so the information exists where the picker actually stands rather than only in a central system.
- When an order is allocated, the system selects the batch with the nearest date among those available, regardless of when any of them arrived.
- Physical arrangement supports the instruction. Stock is put away so the nearest-dated cartons sit at the front, since a rule the picker has to fight is a rule that will be broken under pressure.
- Reserve and bulk positions fall under the same rule, since the earliest-dated goods drift to the back as fresher pallets arrive in front of them, and a discipline covering only the pick face abandons precisely that population.
FEFO (First Expired, First Out): A Worked Example
| Batch | Manufactured | Expires | Quantity | Picked under FIFO | Picked under FEFO |
|---|---|---|---|---|---|
| A-114 | 12 Jan | 11 Jan next year | 400 | First | Second |
| A-118 | 20 Jan | 19 Jul | 350 | Second | First |
| A-121 | 02 Feb | 01 Aug | 500 | Third | Third |
A distributor holds three batches of the same product with different shelf lives.
Batch A-118 was made after A-114 and expires six months sooner, because it carries a shorter approved shelf life. Under first in, first out the older batch goes first and A-118 sits until it is close to expiry, at which point 350 units are written off. Under first expired, first out the picking order follows the expiry date and nothing is lost. The two rules coincide only where every batch has an identical shelf life, and that assumption is precisely what breaks down in pharmaceuticals and food. A warehouse system configured for FIFO will follow it silently and correctly, and still produce expiry write-offs nobody can explain.
Common Mistakes With FEFO (First Expired, First Out)
The rule is easy to adopt and frequently impossible to execute.
- Adopting the policy while the system holds only receipt dates, which leaves the picker no way to comply and makes the rule an aspiration.
- Capturing expiry at receipt but not against the storage location, so the information exists somewhere nobody standing at the rack can reach it.
- Assuming later deliveries always carry longer life, which is exactly the assumption that fails and the reason the rule exists.
- Applying it to the pick face and ignoring bulk locations, where the oldest stock accumulates behind newer pallets.
- Finding it only at a stocktake, where out-of-date units recovered from behind fresher pallets represent months of accumulated loss.
- Rotating on the shop floor while the replenishment feed ignores the rule, so the discipline lasts exactly as far as the pick face.
