It's not always easy to figure out when to change the GTIN on an existing product.

‍

You must change the GTIN on a product in the following situations:

• Changing functionality or recipe, e.g. ingredients
• Change in net content
• Change in dimensions or gross weight by more than 20%
• Adding or deleting a certification mark, e.g. kosher or CE
• Change of primary brand, i.e. the brand known to the consumer
• A time-bound or promotional product
• Changing the number of units in the package/box
• Modification of a predefined combination, for example, in a package of two or more consumer units that are combined and sold as one consumer unit
• Change of a price, printed on the packaging
• Launch of a brand new product
