The other option is to prepay tarrifs during the purchase of an item. Fedex and DHL usually offer this service which includes epedited customs clearance.
Is it really? It sounds like you're implying it's some kind of woeful ignorance, but I say it's perfectly reasonable:
1. Each US state is already in a open-borders zero-tariff framework with all other states, which covers a very large portion of what people purchase.
2. Until recently, most individual consumers didn't need to think about tariffs on international goods, since most purchases were <$800 and covered by the de minimis rule. (Which AFAICT was in place for ~80 years.)
* 1938 to 1977: $1 ($22 -> $5.43)
* 1978 to 1992: $5 ($25 -> $11.50)
* 1993 to 2014: $200 ($446 -> $272)
* 2015 to 2025: $800 ($1087 -> $800)
* 2026 to ????: $0 ($0 -> $0)
The point I'd like to make from this is that Americans under 50 weren't adults-with-money in time to ever encounter those older more-restrictive spans. If you're under 28, the highest-exemption is the only situation they've ever known until now.
