Go to r/leatherclassifieds and post how much you want to pay and you’ll get the best belt I bet you.

There is really no standard or regulation, controlling the labeling of leather products that I’m aware of. There are a lot of industry terms, but as long as it’s made out of some kind of leather, you can call it leather.

If it says “genuine” leather it’s almost always the equivalent of chopped up pieces of leather glued together. Like mdf is to solid wood.
