There's lots of stuff like that, the way chickens and eggs are cleaned etc.

It sometimes is annyoying though, especially around foods and medicine when something is not yet approved in Europe e.g. It's really hard to get Allulose (sugar alternative with similar properties benefitting baking); As far as I can tell it's not actually "illegal" in Europe, it's just not approved as a food, so no-one risks importing it..
