GTIN Management Rules

Declared formulation or functionality

“Functionality” is defined as the particular use or set of uses for which something is designed. “Formulation” is defined as a list of the ingredients or components used to create a trade item.

This GTIN Management Standard SHALL NOT be used for identifying non-new trade items. For rules on identifying non-new trade items, see GS1 General Specifications.

A change to the formulation or functionality of an existing trade item that affects the legally-required declared information on the packaging of a product and also where the brand owner expects the consumer or supply chain partner to distinguish the difference requires a new GTIN. Both conditions must be met requiring the assignment of a new GTIN.

Hierarchy level of GTIN assignment

  • The GTIN change must occur at the retail consumer trade item/base unit level.
  • A unique GTIN is assigned at every existing level of packaging hierarchy above the retail consumer trade item/base unit level.

Example business scenarios that require GTIN change

  • Ammonia (a potentially hazardous ingredient) is added to the formula which may cause an issue with how consumers/trading partners currently use or store the product.
  • A product includes nuts, which introduces a new allergen which is a legally-governed declaration and must be distinguishable by the consumer.
  • A change in formulation reducing sugar by 50% to make the trade item “low sugar ”.
  • Previously frozen salmon is now sold as fresh salmon

Additional information

  • New GTIN assignment is NOT required when declaring existing functionality that was previously present, but not declared on the package, and is now being marketed on new packaging.
  • Local, national or regional regulations may require more frequent GTIN changes. Such regulations have precedence over the rules provided within the GTIN Management Standard.
