Haven't tariffs been paused since they've been announced?
Some of them yes, some of them no. There are now several thousand different "tax brackets" for imported items and the apparent rates on them fluctuate by the day.
Most global post offices are just suspending packages to the US because they don’t know what the price is or how to pay it.
this isn't true, tariffs are assessed within the US by the receiving firm, not on the sender's side. We run a business with a foreign supply chain and our suppliers have changed nothing, we just get an extra bill to pay to the government when our inventory arrives.
