I'm friends with someone who works for a logistics company, and collecting the tariff from each company, and sending to the government, is part of the service they provide. It actually wasn't a complicated part of their business until a couple months ago, because of how little that aspect would change. But now their compliance teams have to read the Federal Register every day to keep up. They are getting stuck in the middle of this, because they quote the delivery costs to the company, but by the time the shipment arrives, the tariff has suddenly risen and then the company complains "that is not the cost you quoted us".
