What is FEFO inventory rotation

FEFO means first expired, first out. You rotate inventory so the lot with the earliest expiration date leaves first. In wholesale, that helps you keep dated goods moving in order and reduces the chance that usable stock sits past its date.

FEFO is different from FIFO, which means first in, first out. FIFO follows receipt date. FEFO follows expiration date. If two lots arrive on the same day, FEFO still sorts them by date code, not by when you received them.

You use FEFO when product life matters. That includes food, beverage, supplements, personal care items, and other goods with printed dates or lot codes. The rotation rule should be visible to your warehouse team, your buyers, and anyone who picks orders.

FEFO starts with lot-level receiving. You record the lot number, the date code, and the expiration date when product comes in. If you do not capture those fields at intake, you cannot rotate stock with confidence later.

At pick time, the system or pick list should show the lot that expires first. The picker takes that lot before later-dated inventory. If you move stock across bins or stores, the rotation rule needs to travel with it so the age of the goods stays clear.

A clean FEFO process depends on consistent labeling. The warehouse needs one source of truth for the date code, one storage rule for where the lot sits, and one order rule for what ships. When those three pieces match, the team can follow FEFO with less guesswork.

FEFO is a control against shrink and write-offs. When dated goods are picked in expiration order, you reduce the chance that older inventory is missed until it becomes unsellable. That matters in wholesale, where inventory often moves through multiple stores, cases, and replenishment cycles.

It also supports customer service. Retailers and foodservice buyers expect fresh product and predictable shelf life. If your team ships newer lots while older lots sit behind them, you can create returns, credits, and complaints that take time to unwind.

FEFO helps with compliance and traceability as well. If you need to answer a recall or a quality question, lot records matter. A warehouse that tracks expiration dates at the line level can identify what shipped, where it went, and which lots remain on hand.

A beverage distributor may receive the same SKU in several lot runs. One lot expires in March and another in June. FEFO sends the March lot first, even if the June lot arrived earlier or sits closer to the dock.

A supplement brand can use FEFO for inventory that carries a best-by date. The picker should see the earliest date first, then the next lot after that. If a lot is reserved for a specific customer, that reservation still needs to respect the expiry order.

FEFO is not a fit for every item. Durable goods without a meaningful expiration date do not need it. For those items, FIFO or a simple stock location rule may be enough. The right rotation method depends on whether the date on the package affects saleability.
