Any dimensional change of more than 20%, but net weight remains unchanged.
New GTIN for:
Existing higher-level packaging
Hierarchy level of GTIN assignment
Example business scenarios that require GTIN change
Inventory and logistics systems need to be updated to ensure optimal space allocation.
Consequence if rule not applied: 20% rule meets reasonability test (e.g. 0% is unacceptable to suppliers, and 100% is unacceptable to customers.) Note: Any change in Net Declared Weight requires a new GTIN.
