3: Understanding GTIN rules

A new product will always require a new GTIN, but you will also often have to allocate a new GTIN when you have made changes to a product, for example, if the ingredients have changed significantly, or its size or colour.

Specific rules for retail

There is a specific set of allocation rules and practices that applies to retail – and it’s important to follow them. If you don’t, you could add unnecessary costs to your business, by having to replace all the packaging on a certain product. In extreme examples where important ingredients have changed you could find yourself trading illegally, or it could even affect people’s health.
