Loose produce item is sold as an each (individual piece) then cut and sold weight.
Where a loose produce item is sold as an each (product 1), then cut and packaged to be sold by weight (product 2), product 1 and 2 require separate unique GTINs.
New GTIN for:
Existing higher-level packaging
Hierarchy level of GTIN assignment
Example business scenarios that require GTIN change
A whole watermelon is sold for $4.00 each. The retailer decides to cut the watermelon into halves and sell the quarters for $1.99 per kilo/pound
Consequence if rule not applied: GTIN assignment would be inaccurate
