I know that sometimes companies create multiple SKUs of products to get around certain restrictions. For example, if the Coca-Cola in Poland is only sold in Poland, and is different from what's sold in France (let's pretend your flag is on the can) - then they're technically "different products" and don't have to follow the same regulations.

I know the WD easy stores sold at best buy are best buy specific so that they don't have to price match them with competitors, even though what the competitors sell have identical internals.
