I mean it’s very simple. A tariff is what you pay the government to get stuff released from the port of entry.
You buy a $1000 DJI quadcopter that was manufactured in China, if Trump does his “60% on everything from China” tariff the US government says you have to pay them $600 or it goes back on the boat.
The complicated part of tarrifs is stuff like “are X-men action figures human or non-human toys” because those get different rates. Not what tariffs “are”.
To cover what? DJI isn’t paying anything extra.
If they raise the price to $1700, then the tariff would be $1020 to the US government, again by you, and you would pay $2720 total to get your thing, split between DJI and the port authority.
After they put it on the boat DJI doesn’t care. They have their $1000. If they feel like it they can add the tariff charge and handle that for you, that’s how it usually happens now, but they don’t have to. You’ll just get a letter from the port authority about the charges needed to release your item.
