1. A branded product listed as generic
The unit or its packaging visibly carries a brand, and the ASIN says generic. This is the most common start and the easiest to get wrong, because the instinct is to argue the product is basically unbranded.
If the brand is there on the box, it is there. Amazon's generic product policy limits how generic records are created and repurposed, so the route is usually a corrected or properly created branded record. It is never removing or covering genuine brand markings to fit the existing page.
