I think you might be doing yourself a disservice here, and making assumptions through a fear of the unknown.
...
The taxes and tarrifs you fear apply essentially to large commercial importers, who will be buying in bulk, shipping in packed containers and selling on for high profit.
...
I frequently send items across the Atlantic, and have never known an item to be surcharged after passing through US customs.

Just as a follow-up for anyone else who stumbles on this thread, I decided to take the plunge and order directly from Lochcarron in Scotland. I wasn't given a choice in courier; they shipped via UPS. Several weeks after receiving my package from Lochcarron, I received a surprise bill from UPS for a 25% tariff plus a $25 brokerage charge. So no, tariffs don't "apply essentially to large commercial importers". Although, after looking into it further, I perhaps could have avoided the tariff charge if I kept the value of my order under $800, which might have qualified for a "de minimis" exemption. I wish I had known, as I could have saved myself hundreds of dollars. This an example of one of the unknowns I was concerned about, and I was absolutely right to be concerned because it came back and bit me.

If you're reading this in the future, be aware that it is my understanding that the US government is currently trying to do away with de minimis exemptions, so I don't know what your experience will be.
