I wonder why English decided to narrow its meaning. Well I guess a language doesn’t decide anything, but I think you know what I mean. In many EU countries it simply means “cost list” or “price list” which can be for import duties but also for a range of other things.

It’s very nice to have it called tariff in basically every EU country though. We get green energy tariffs and if it was called something different in each country they wouldn’t be fun.
