Batches and Best-Before Dates in Fulfillment

In fulfillment, batches and best-before dates play a critical role. They affect warehousing, product quality, and customer satisfaction — and keeping track of batch-level stock isn't always easy. In this post, we look at why these two topics matter and how to handle them in fulfillment and beyond.

Batches and Best-Before Dates in Fulfillment

In the world of fulfillment, batches and best-before dates play a decisive role. They affect warehousing, product quality, and customer satisfaction. And it's not always easy to keep track of batch-level stock levels. In this post, we'll take a closer look at why both topics matter and how you can handle them in fulfillment and beyond.

We'll show you which areas batch-pure storage and best-before dates are particularly important in, and why following these rules has a direct impact on your business success.

What are batches and LOTs?

Batches (often also called LOTs) are specific quantities of products that were manufactured or processed under the same conditions. With batches, you ensure consistent quality and a way to identify products. That's why every batch gets a unique batch number, also called a LOT number. With it, a product can be traced back to its producer and ingredients. Batches are especially critical in pharmaceuticals, food, and cosmetics, because traceability of products and assurance of product quality are essential. By managing and tracking batches, companies can react quickly to quality issues, run recalls, and ensure regulatory compliance.

LOT tracking: what is batch traceability and how does it work?

LOT tracking, or batch traceability, follows the path of a product batch across the entire supply chain — from manufacturing all the way to the end consumer. Products affected by quality issues or recalls can be identified precisely and quickly this way. In some industries, like food and cosmetics, batch traceability is even a legal requirement.

Batch or LOT numbers usually consist of a letter and a series of numbers. The letter stands for the month of manufacture. In our example, the letter G stands for July. The other numbers provide information about the production date and the earliest expiration date.

Here's what kind of information about a product can be derived from a batch number:

To trace a batch seamlessly, several other data points besides the LOT number are required by law. These include, for example:

  • Volume and quantity
  • Supplier information (name and address)
  • Identification of raw, auxiliary, or operating materials
  • Product details
  • Date of the production period

In case a product needs to be recalled, you can trace it seamlessly through inventory management or ERP systems (Billbee, Xentral & co).

Why is batch traceability important in fulfillment?

LOT tracking, or batch traceability, ensures quality, safety, and transparency along the supply chain. But not only that — it also has a major impact on warehousing. Only by labeling batches can you achieve batch-pure storage. But what does that mean? Simply put: each storage location is filled with only one specific batch. This requires an efficient warehouse management system. Fulfillment providers help automate these processes and create transparency for buyers.

Other important aspects of batch traceability in fulfillment include:

  • Quality control: The quality of packed shipments has to be on point, especially when companies outsource their fulfillment.
  • Enabling product recalls: Affected batches and the corresponding orders need to be identified quickly to eliminate potential dangers and quality issues.
  • Efficiency in warehousing: Optimizing processes, resources, and systems ensures a smooth flow of goods, maximum use of available space, and lower costs at the same time.
  • Boosting customer satisfaction: By making sure buyers only receive flawless products, you meet customer needs with outstanding product quality.

The best-before date (BBD)

Another key point in efficient and, above all, safe warehousing: BBDs on products. Here too, sticking to a few important rules is essential. We'll show you what those are now.

How is the best-before date defined?

The term best-before date (BBD) is used in logistics to indicate the period during which a product, when stored properly, retains its quality. The BBD is usually shown on perishable products like food and medicine, but also on cosmetics, for example. According to the German Federal Office of Consumer Protection and Food Safety, BBDs must be shown under Article 19 of the EU Cosmetics Regulation if the shelf life is 30 months or less.

Only when you take the BBD into account during storage and shipping can you ensure that products are prioritized in time before the BBD expires. That way, the longest possible remaining shelf life after purchase is guaranteed.

How are BBDs calculated?

Manufacturers and labs run tests and analyses to calculate the minimum shelf life of products. Various factors are taken into account, including the composition, type of ingredients, storage conditions, and expected shelf life. There's a distinction here between the best-before date and the use-by date.

When the best-before date has passed, it usually doesn't mean that, for example, a food has gone bad. It only indicates the date until which a product retains its properties under appropriate storage. So up to that date, a product is at its best. After that, it doesn't necessarily become inedible or harmful to health.

Similar rules apply to cosmetic products. Cosmetic items are declared with different shelf lives:

  • Shelf life of less than 30 months: An hourglass symbol or the wording "Best before" together with the date must be used.
  • Shelf life of more than 30 months: For longer shelf life, the symbol of an open cream jar is used. The period of use after opening is shown on it. For example, the symbol with "6 M" indicates that this product can be safely used for the first 6 months after opening.

It's different with a use-by date. This applies, for example, to highly microbiologically perishable foods. Packaging therefore has to carry the wording "use by …" because there are microbiological risks to human health after the date has passed. The specified storage description — for example, refrigeration temperature — is especially important here.

Why is the best-before date important in fulfillment?

The best-before date depends on many factors. To deliver on those, the right storage of products plays an essential role — from the moment of manufacture to the end customer.

In fulfillment, you or your provider have to pay attention to the best-before date because:

Customer satisfaction plays a central role: Fulfillment providers are responsible for properly processing buyers' orders and making sure they receive high-quality products. By carefully checking and respecting BBDs in fulfillment, you make sure that only flawless products are delivered — which in turn leads to higher customer satisfaction.

Companies have to comply with legal requirements: In the European Union, there are regulations that govern the labeling and sale of products with expired shelf life. Stores can avoid legal issues and prevent possible fines or sanctions.

Another important aspect is avoiding returns. If customers receive products with expired shelf life, they're likely to send a return. That leads to extra costs and effort in fulfillment. By strictly observing the best-before date, those costs are kept to a minimum.

Challenges in managing batches and BBDs

Managing batches and BBDs comes with a few challenges. To ensure efficient management of batches and best-before dates, we have to put effective systems and processes in place. Some fulfillment providers offer smart solutions here that break down the complexity of managing batches and best-before dates.

Complexity of batch and best-before management

A few factors make managing batches and BBDs very complex. Larger product quantities have to be precisely monitored and documented. Tracking and managing individual batches can also be very time-consuming and error-prone. That's why smooth coordination between different parts of the company is needed — like seamless communication and an effective flow of information between purchasing, warehousing, sales, and marketing.

Legal requirements around batch and best-before management add even more complexity. To identify expiring products in time and minimize losses, efficient inventory management and forecasting are required. Employees have to be trained accordingly to handle expired products correctly.

Best practices for managing batches and BBDs in fulfillment

Effectively managing batches and BBDs in fulfillment is important to ensure product quality and minimize risks. Companies can apply best practices to handle this task successfully, like:

  • Warehousing: Assign dedicated storage areas for products with different batches and BBDs. This allows for better control and organization of stock. Without real-time visibility of stock levels, it can be hard to know exactly how many products you have on hand. This is especially true for information about best-before dates and batches. You need to know which products are about to expire so you can drive sales with discounts before the shelf life is reached.
  • First in, first out (FIFO) principle: Picking products based on the FIFO (First in, first out) principle is critical for managing best-before dates and batches. It makes sure that products with the shortest remaining shelf life are picked and shipped first. That lowers the risk of customers receiving expired products. Instead, you send them products with the longest possible shelf life, which boosts customer satisfaction and reduces the risk of product recalls.
  • Tracking system: Using systems to track batches and best-before dates improves reliability. That can be specialized software or a barcode system to keep an overview of inventory.
  • Regular inventory checks: Through regular inventory checks, you make sure that products with shorter best-before dates are identified and sales are planned accordingly.
  • Labeling: Each batch should be clearly labeled to avoid mix-ups. This includes information like the batch number, manufacturing date, and best-before date.
  • Traceability: With a traceability system, you can react quickly and precisely in case of product recalls or quality issues. Affected batches are identified and appropriate measures can be taken. With Zenfulfillment, you can also export all affected orders to email the relevant buyers in case they need to be notified quickly during a recall.
  • Locking batches based on storage location: Sometimes specific batches need to be locked from picking. This can happen for a variety of reasons, like quality control or product recalls. The ability to lock specific products from picking is helpful. It can also come in handy for campaigns tied to a specific product edition. That way you can be sure batches don't get mixed up.
  • Disposal of expired products: Using an efficient disposal strategy for expired products makes sure that already-expired products are no longer used.

With the Zenfulfillment Logistics Operating System®, you get tailored solutions for managing batches and meeting best-before dates in fulfillment. These include, for example:

  • Real-time visibility of stock levels, including historical data for inventory by BBD and batch

  • Automatic email notifications about products that are about to expire
  • Ability to search orders by specific batches
  • Locking specific batches from picking with a single click
  • Easy traceability of which batch was used at the order level
  • and much more.

The manual back-and-forth with your warehousing partner around best-before dates and batch management can be frustrating, especially during urgent product recalls. With the Zenfulfillment Operating System, you have full control over BBDs and batch management. Thanks to real-time visibility of stock levels, easy traceability of batch information, and the option to lock batches from picking, smooth management is possible without the headaches. That means: you no longer have to worry about expired products being shipped to customers, and you no longer have to spend time tracing back which batch was used at the order level.

It's not just about fulfillment: which other areas are affected by BBDs and LOTs?

Of course, the importance of batches and BBDs doesn't only extend to fulfillment, but also to:

  1. Product development and marketing: When developing new products or running marketing campaigns, batch and shelf-life data needs to be taken into account. One example is carefully planning campaigns to make sure products still have enough shelf life during the promotion. The other way around, marketing campaigns can also be used to specifically sell off products that are nearing expiration. The bottom line: product availability and shelf life have to be well aligned to avoid customer frustration.
  2. Quality assurance and compliance: Batch and shelf-life data plays an important role in quality assurance and meeting legal requirements. Monitoring and documenting batch and shelf-life information is essential.
  3. Customer service and complaints: In customer service, employees need to be trained to handle inquiries or complaints about expired products appropriately. Customer service teams should be informed about current shelf-life data and offer suitable solutions, like refunds or product replacements.

It's important that batch and shelf-life data is coordinated across different parts of the company. By integrating this information into the various business processes, you ensure smooth operations and happy buyers.

Batches and best-before dates — a challenge for E-Commerce stores

Batches and best-before dates are critical pieces of information that E-Commerce stores have to take into account. They influence not only storage and fulfillment, but also quality assurance and customer satisfaction. If you or your provider work cleanly here, you create the best possible transparency.

FAQs

What are batches?

Batches (also LOTs) are groups of products that were manufactured, processed, or packaged in a specific period using the same production batch or the same batch of raw materials.

What is a LOT number?

A LOT number, also called a batch number, contains the most important information about a batch, like the manufacturing date and information about expiring components.

Why is batch traceability important?

Batch traceability (or LOT tracking) is important so you can precisely identify, recall, and ensure consumer safety and supply-chain quality assurance for the products affected in case of quality issues, recalls, or other incidents.

What does best-before date (BBD) mean?

The best-before date, or BBD, indicates the date by which a product, under recommended storage conditions, should retain its specific properties like taste, smell, texture, and quality without posing a risk to health.

How is the BBD calculated?

BBDs are usually determined through lab tests and monitoring of product quality over a specific period to determine how long the product retains its desired properties under appropriate storage conditions.
