New product versus product change
When making decisions about product identification, it is important to understand the differences between a NEW product and changes to an existing product.
New products are those which do not currently exist in a brand owner’s product offering and are new to the marketplace. A new product should be considered an “addition” to a product offering. The GTIN Management Rules require that if a product is new, it should always be assigned a unique GTIN to accurately distinguish the new product from any product that is currently available.
Changes to existing products are considered “replacement products” (the previous version will no longer exist once the replacement product has flowed through). The GTIN Management Rules define when a change to certain attributes of an existing product requires a new GTIN.
