We’ve used Bambo, made in Denmark for my child. They’re distributed in a number of countries, including Germany and France. Online pharmacy/parapharmacy stores like Atida often carry them at a good price.
Not sure if it'll make any difference, but might be worth searching for "nappy" (the equivalent word in English) rather than "diaper" (American word) to avoid US products.
Most of Europe doesn't speak English as a first language, I'm gonna continue searching for plíny. I doubt most people want to order from two countries over, at least I'd rather buy from official local distribution.
