So, Royal Mail now has a system in place for dealing with US tariffs called "PDDP". First postal system in the world with a solution!
For those of you who for some reason need to ship an item of US origin back to the US (warranty issue, received an defective item purchased from a US seller etc), there is only a small handling fee, no added tariffs.
This is a test screenshot from Royal Mail, the item is a figmentary loudspeaker made in USA with a value of £100. Note that this is calculated for an ITEM RETURN, not a sale. I haven't checked how they would calculate for a SALE of a US made item, such as a US made collectible shipped from a UK seller to a buyer in the US.
Located in Sweden, I myself use Swedish Postnord rather than UK Royal Mail, but only Royal Mail has a system in place to deal with collecting tariffs, and I assume other countries postal systems will work in a similiar way . 50p seems reasonable, I'm sure that is much less than any courier or alternate will be charging.
