Analysis
Subheading 3824.99 covers other, within heading 3824. 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 20 US tariff lines below it are national.
The spread of 6.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.5%, applies to 3824.99.19 (cultured crystals (other than optical elements of…) and 3824.99.25 (aqueous mixtures of triphenyl sulfonium chloride…).
5 of its 20 lines with a percentage rate are duty-free at the general rate (25%) and 15 are dutiable, from duty-free up to 6.5%. The median line pays 4.8%.
Its 20 lines start with 3824.99.11 (in the form of ingots), 3824.99.19 (cultured crystals (other than optical elements of…), 3824.99.21 (consisting wholly of substances found naturally…) and 3824.99.25 (aqueous mixtures of triphenyl sulfonium chloride…); the full list is in the table below.
