The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 2 US tariff lines below it are national.

1 of its 2 lines with a percentage rate are duty-free at the general rate (50%) and 1 are dutiable, from duty-free up to 3%. The median line pays 1.5%.
