Buying CBD isn't as simple as it seems. On your product's packaging, you'll find a series of numbers, dates, and labels that can sometimes seem mysterious. Don't worry—I'll help you figure it all out!


Things to remember

  • The lot number allows a product to be linked to a specific batch and facilitates its traceability.
  • The best-before date, net weight, country of origin, responsible operator, and storage conditions are details that should be verified.
  • A vague label—with no clearly identifiable batch number or person in charge—warrants a few questions before making a purchase.

Start by identifying the product


Before looking at the numbers, check the product name.


A flower, an oil, a CBD resin, or a hemp-based edible product may not necessarily be subject to the same labeling rules.


For prepackaged food products, European regulations require, among other things, information such as the product name, ingredients, net quantity, best-by date, storage conditions, and the responsible operator.


So I suggest you start by asking yourself,“What do I actually have on my hands?”


This first step then helps determine what information should normally appear on the packaging.

The lot number serves as the product's identification number


Do you sometimes see an “L” followed by numbers or letters? This is usually the lot number. For the products in question, the lot number identifies a series of units that were produced, manufactured, or packaged under similar conditions. It therefore facilitates traceability.


And this little code becomes particularly important when it comes to test results. If your package has batch number L2408, but the test report provided is for batch number L2311, you cannot assume that the test results apply to your product.


The lot number can be printed directly on the label or added to a small sticker. The most important thing is that it be clearly identifiable.

DDM: Be careful not to confuse it with the harvest


The DDM, or minimum durability date, indicates the date until which a product retains its properties under the specified storage conditions. It corresponds to the phrase “best before…” for the foods in question.


But it doesn't specify the harvest date. So, for a CBD flower, there can be three different dates:

  • the harvest date;
  • the packaging date;
  • the DDM.

The first provides information on the age of the plant material, the second on its packaging, and the third on its shelf life under the specified conditions.

Net weight is essential for comparing prices


1 g, 3 g, 5 g, 10 g, etc. Understanding the sizes and quantities of CBD products is important for comparing prices.


The net weight indicates the amount of product contained in the package. This information may seem obvious, but it becomes really useful when you're comparing prices.


A flower that costs €30 may seem cheaper than one that costs €35. But if the first one weighs 3 g and the second one weighs 5 g, the comparison looks very different.


I recommend checking the price per gram rather than just the listed price. The same logic applies to oil. Check the total volume and the stated concentration.

The description “European origin” is too vague


“European hemp” may sound reassuring, but this label doesn’t necessarily tell you where the plant was grown. A product may be manufactured or packaged in one country while the hemp comes from another.


If a salesperson tells you a flower is Italian but the label simply says “made in Europe,” ask yourself whether the plant was grown in Italy or if the product was merely packaged there.

Who is responsible for the product?


Find out who the responsible operator is for placing the product on the market when required by the product's regulatory framework.


For food products, European regulations require, among other things, the name or business name and address of the responsible operator. You must be able to identify a company and, depending on the product, the legally responsible operator.

Check the storage instructions


The brief notes on preservation may seem minor, but I promise you they're not.


For the products in question, specific storage conditions must be indicated when necessary. Properpackaging of flowers and resins is important for preserving the quality of your product for as long as possible.


And don't forget that storage conditions before you buy are just as important. A label doesn't always tell you how the product was stored in the warehouse or on the shelf.

Omissions that should catch your attention


Here's my little checklist for you. A label warrants further scrutiny when it doesn't clearly identify:

  • the product;
  • the quantity;
  • the lot;
  • the applicable date;
  • the person in charge, when this information is required;
  • storage conditions, when necessary;
  • the source, when it must be cited.

However, the absence of a specific requirement does not automatically constitute a violation, as the obligations depend on the product category and the relevant market. What should really raise a red flag for you is the accumulation of gray areas.


A very vague label, a salesperson who can't specify the origin, no lot number, and no documentation to verify the information provided—I wouldn't take that lightly.
