Kilts are about to get more expensive

I hope this post doesn't veer too close to the line on politics, and I hope we can resist discussing politics, but I thought people should know. Here in the US, in about two weeks, there will be a new round of tariffs imposed. They will affect, amongst other things, wool clothing from the UK and Scotch whisky.

I would assume that this means any wool items (kilts, jackets, hose, garters, bonnets, and the like) that come into the US from the UK after October 18th will be subject to the tariffs. What I'm not sure about is how they are applied to, say, an individual package sent from a kiltmaker to an individual. When tariffs are applied, do these get flagged based on the import paperwork? If so, does the buyer have to pay the tariff to US Customs in order for them to release the package? How does it work? Or does it even affect individually purchased items like these? Or is it only applied to business shipments going from suppliers in the UK to retail companies?

*edited to add more questions:

I'm assuming that US-based kiltmakers like USA Kilts will end up paying more for bolts of wool tartan material, and that cost will be passed on to customers. But PV material may not be affected?
