The difference between DLC DLUO DDM is essential for any e-tailer or logistician handling perishable products. The SLED refers to sanitary safety, the MDD to product quality, and the DLUO is the former term for the DDM. A clear understanding of these concepts helps to secure sales, improve perishable stock management and avoid logistical errors, thanks to improved traceability, the FEFO method and automation.
The DLC DLUO DDM difference has a direct impact on your business. It determines what you can sell, what you need to withdraw, how you need to organize your perishable stock management and what controls you need to put in place to avoid errors.

For an e-tailer or logistician, the subject is more than just labeling. It involves e-commerce food safety, traceability, batch rotation, order preparation and customer satisfaction. Poor date management can lead to health hazards, non-compliance or lost margins.
The economic stakes are far from marginal: according to Eurostat, in 2025, the European Union generated 58.2 million tonnes of food waste in 2023, or around 130 kg per capita.
Understanding the basics: BBD, UBD and DDM
Before talking logistics, it’s important to get the definitions right. The difference between BBD, UBD and DDM is not a theoretical nuance: it changes sales rules, the way products are stored and the level of vigilance expected in the warehouse. To manage sensitive products properly, your teams need to know exactly what each term implies.
Use-by dates: a question of health
The best-before date applies to microbiologically highly perishable foods. It appears with the words “best before”. Once this date has passed, the product may become hazardous to health.
For professionals, the consequence is immediate: a product with an expired use-by date must no longer be marketed. The rule applies to purchasing, storage, preparation and dispatch. In e-commerce, this means thinking in terms of the actual delivery date, not just the preparation date.
In other words, best-before dates call for strict batch management. You need to be able to identify high-risk products, block them in time, and avoid shipping an item whose use-by window is too short.
From DLUO to DDM: what has changed?
The best-before date has been replaced by the date of minimum durability. This is now the correct regulatory term. The change is important for your content, procedures and product communication.
The date of minimum durability is expressed as “best before”. Once the date has passed, the product can still be consumed if the packaging is intact and has not been altered. However, it may have lost its taste, texture, effectiveness or nutritional qualities.
This is the key to understanding the difference between DDM and DLC: DDM is about safety, DDM is about quality. For your operation, this means two different logics of control, rotation and commercial decision.
What are the major differences for your e-commerce business?
Once the definitions have been established, it’s time to translate them into concrete decisions. For an e-tailer, this is not just a legal issue: you need to know what to sell, what to block, what to promote, and how to maintain a consistent customer experience. This is where date management becomes a real performance issue.
Consumer vigilance confirms the importance of the subject: according to theEFSA in its Eurobarometer 2025, 7 out of 10 Europeans say they are personally interested in food safety, and 46% cite it as one of the factors influencing their food choices.
Health risks vs. loss of quality
With an expired use-by date, you’re dealing with an e-commerce food safety andfood hygiene issue. The risk is sanitary. With an expired best-before date, you’re dealing with perceived quality. The product may still be consumable, but it no longer necessarily guarantees the expected level of quality.
This distinction changes the wayperishable inventory is managed. A batch with a short best-before date requires close monitoring. A batch with a short best-before date can still be sold, destocked or allocated to a specific channel, provided its actual condition is under control.
To limit errors, your teams need to be able to answer three questions:
- is this lot still for sale?
- on which channel can it be broadcast ;
- which customer promise remains compatible with its date.
Legal framework for sales and promotions
The legal framework is stricter on the best-before date than on the sell-by date. An expired BBD prohibits sale. An expired best-before date can be marketed if the product remains healthy, if its packaging is intact and if product information is correctly managed.
For a retailer, this difference opens up a lever foroptimizing food stocks. Short-dated products can be directed towards promotional operations, destocking circuits or more intelligent management of unsold stock. This helps prevent waste and protect margins.
But this flexibility requires real discipline. The more you work with short dates, the more you need to master thelabelling of perishable products, the regulations on BBD and DDM, and the coherence between your stocks, your sales channels and your logistics rules.
Optimize logistics for short-dated products
Understanding the rule is not enough. It must then be applied without error, even when several batches coexist with different dates. This is where logistics play a decisive role: good organization secures sales, reduces waste and protects customer satisfaction.
The importance of batch traceability
Visit batch traceability is essential when managing perishable products. On receipt, each batch must be recorded with its date. In storage, each quantity must remain attached to a location. In preparation, the operator needs to know which batch to pick.
Traceability in food logistics serves both day-to-day operations and incident management. In the event of a supplier alert or recall, you need to be able to find out immediately which units are still in stock, which orders have been dispatched, and which customers are concerned.
Reliable traceability makes it possible to :
- secure preparations on the right batches;
- quickly isolate an anomalous batch;
- better arbitration of short-dated products;
- strengthen your logistics compliance.
The FEFO method: First Expired, First Out
For perishable products, the FIFO method method quickly shows its limitations. FIFO (First In, First Out) means that what goes in first, goes out first. However, two batches may be received at different times and have very different dates.
The method FEFO method, or First Expired First Out, consists in taking out first the batch that expires the earliest. This is the most appropriate logic for managing expiry dates and reducing losses.
FEFO improves rotation, limits destruction and protects the customer experience. It is particularly useful for e-commerce warehousing of foodstuffs, fresh produce and all items whose date influences their commercial value. Provided, of course, that this rule is automatically applied in the warehouse.
Automate date management with an omnichannel WMS
When volumes increase, manual controls are no longer sufficient. A spreadsheet can list dates, but it doesn’t guarantee the right allocation of stock or the right decision at picking time. To secure your operations over the long term, you need more structured management.
This is where the link between WHO, WMS and TMS becomes useful. TheOMS (Order Management System) centralizes orders and directs the right flows. The WMS (Warehouse Management System) controls batches, dates, locations and preparation rules. The TMS (Transport Management System) helps to adapt the carrier and shipping method to the time constraint, which is essential for sensitive or short-dated products.
Best-before alerts and virtual inventory management
A stock management software or WMS software for the food industry allows you to associate each product with a batch, a date, a location and a release rule. This makes it possible to automate expiry alerts, block certain batches and distinguish between physical stock and stock actually available for sale.
This virtual stock logic is essential in an omnichannel environment. A lot physically present in the warehouse is not necessarily saleable on all channels. It may be too short for standard delivery, reserved for destocking or excluded from a service promise.
Reduce waste and maximize profitability
Automated date management helps to reduce food waste, limit avoidable destruction and improve profitability. You can identify at-risk batches earlier, arbitrate more quickly, and better dispose of products that can still be recycled.
It also reduces picking errors. The operator is guided to the right location, the right batch and the right picking order. So you avoid shipping the wrong product, while streamlining warehouse operations.
With an omnichannel WMS, the management of perishable products no longer relies on individual vigilance. It is based on reliable, traceable and reproducible rules, and is therefore more compatible with the growth and scalability of operations.
Better date management means better logistics management
Understanding the difference between DLC DLUO DDM is essential, but the real challenge is operational. We need to transform a labelling rule into a system capable of securing sales, preparation and dispatch.
To achieve this, three levers are decisive: batch traceability, a suitable rotation rule such as FEFO logistics, and a tool capable of automating alerts, blockages and arbitrages by batch.

FAQ
Oui, la date de durabilité minimale a remplacé le terme date limite d’utilisation optimale. Ce changement vise à mieux refléter la réalité du produit : après la date, il peut rester consommable, même s’il peut perdre en qualité.
Non. Un produit avec une date limite de consommation dépassée ne peut pas être vendu. C’est interdit et cela peut présenter un danger pour la santé du consommateur.
Un WMS permet d’enregistrer les dates dès la réception, d’associer chaque produit à un lot, d’appliquer des règles de rotation comme le FEFO et d’isoler automatiquement les lots proches de la péremption.
