Lot Tracking, Expiry & FEFO Warehousing in Canada
For anything with a shelf life, the picking rule and the lot record are the difference between a clean recall and a brand crisis. Here's how it should work.
If your products have an expiry date or a lot number — food, beverages, supplements, cosmetics, medical and health products — then how your 3PL tracks lots and sequences picks isn't a detail; it's the core of your risk management. Get it right and a recall is a precise, fast, well-documented event affecting only the relevant lots. Get it wrong and you face expired product reaching customers, an inability to scope a recall, and regulatory and reputational damage. This guide explains lot tracking, expiry management, and the FEFO picking discipline that protects shelf-life-sensitive inventory in Canada.
What lot tracking actually means
A lot (or batch) is a quantity of product produced under the same conditions, identified by a lot number. Lot tracking means recording, for every unit received and shipped, which lot it belonged to — so you can answer two questions instantly: 'which customers received product from lot X?' and 'which lots are still in inventory?' This bidirectional traceability is the foundation of recall readiness. Without it, a recall becomes a blunt instrument: you either pull everything or you guess, both of which are expensive and damaging. Lot tracking turns a recall into a surgical operation scoped to exactly the affected units.
What lot tracking actually means
FEFO vs FIFO: why first-expired-first-out matters
FIFO (first-in-first-out) ships the oldest received stock first. FEFO (first-expired-first-out) ships the stock that expires soonest first — which is not always the oldest received, because production and receiving dates don't perfectly track expiry. For anything with a shelf life, FEFO is the correct rule: it minimizes the risk of product expiring in your warehouse and maximizes the remaining shelf life delivered to customers. Implementing FEFO requires capturing expiry dates at receiving and a system that directs pickers to the soonest-expiring eligible lot — not just the nearest or oldest pallet.
FIFO ships the oldest stock; FEFO ships the soonest-to-expire stock. For shelf-life products they aren't the same — and only FEFO actually protects you from expired product reaching customers.
Expiry thresholds and minimum-shelf-life rules
Beyond picking sequence, shelf-life products need policy: how close to expiry can a unit ship to a DTC customer versus a retailer? Retailers and marketplaces often impose minimum remaining-shelf-life requirements (a product must have a certain percentage of its life left on arrival), and shipping below that triggers chargebacks or rejections. A good operation enforces configurable expiry thresholds — quarantining or flagging stock that falls below the allowed remaining life, and alerting before product becomes unsellable so it can be discounted, donated, or pulled rather than silently expiring on the shelf.
- Capture expiry/lot at receiving for every unit
- Pick by FEFO, not just FIFO or nearest-location
- Enforce minimum remaining-shelf-life rules per channel
- Quarantine or flag stock below threshold automatically
- Alert early so near-expiry stock can be discounted or donated
Recall readiness in practice
A recall is the moment all of this proves its worth. With lot tracking and accurate records, you can identify every affected unit, every order it shipped on, and every customer who received it — and produce the documentation regulators expect — quickly. Recall readiness also means being able to halt further shipment of an affected lot the instant it's flagged, locate remaining inventory of that lot in the warehouse, and reconcile what was produced, shipped, and remains. Canadian food and health-product oversight bodies expect this level of traceability; building it before you need it is the only viable approach.

How ByExpress manages lot and expiry control
ByExpress captures lot and expiry data at receiving, picks by FEFO for shelf-life inventory, and enforces configurable expiry and minimum-shelf-life rules by channel. For food, supplement, beauty, and medical brands, this means clean retailer compliance, minimized waste from expired stock, and genuine recall readiness — the ability to scope and document a recall to the exact affected lots rather than guessing. Combined with appropriate storage conditions, it turns shelf-life risk into a managed, auditable process.
Frequently Asked Questions
What is FEFO and how is it different from FIFO?
FEFO (first-expired-first-out) ships the stock that will expire soonest first. FIFO (first-in-first-out) ships the oldest-received stock first. They differ because received date and expiry date don't always align. For shelf-life products, FEFO is the correct rule because it actually minimizes expired product reaching customers.
Why is lot tracking important?
Lot tracking records which lot every received and shipped unit belonged to, enabling bidirectional traceability. It lets you instantly identify which customers received a given lot and which lots remain in inventory — the foundation of a fast, precise, well-documented recall instead of pulling everything or guessing.
What is a minimum remaining-shelf-life requirement?
Many retailers and marketplaces require that products arrive with a minimum percentage of their shelf life remaining. Shipping below that threshold triggers rejections or chargebacks. A good 3PL enforces configurable shelf-life rules per channel and flags or quarantines stock that falls below the allowed remaining life.
Which products need lot and expiry tracking?
Anything with a shelf life or batch identity: food and beverages, dietary supplements, cosmetics and personal care, and medical or health products. These categories also tend to face the strictest retailer and regulatory traceability expectations, making lot and expiry control essential rather than optional.
How does lot tracking help during a recall?
It lets you scope the recall to exactly the affected lots — identifying every order and customer involved, halting further shipment of the lot, locating remaining inventory, and producing the documentation regulators expect. This turns a recall from a brand-wide crisis into a surgical, auditable event.
