Analysis
Heading 8483 of the Harmonized Tariff Schedule covers transmission shafts (including camshafts and crankshafts) and cranks; bearing housings, housed bearings and plain shaft bearings; gears and gearing; ball or roller screws; gear boxes and other speed changers, including…. It divides into 7 six-digit subheadings and 24 eight-digit tariff lines, with 47 ten-digit statistical suffixes below them.
3 of its 23 lines with a percentage rate are duty-free at the general rate (13%) and 20 are dutiable, from duty-free up to 5.7%. The median line pays 2.8%.
The spread of 5.7 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 5.7%, applies to 8483.50.40 (gray-iron awning or tackle pulleys, not over 6.4…).
1 of the lines carry specific or compound rates (per kilogram, per dozen and so on) rather than a percentage, so their burden depends on the unit value of the goods.
The largest subheadings are 8483.40 (gears and gearing, other than toothed wheels…, 6 lines), 8483.90 (toothed wheels, chain sprockets and other…, 6 lines), 8483.10 (transmission shafts (including camshafts and…, 3 lines) and 8483.50 (flywheels and pulleys, including pulley blocks, 3 lines).
Its median rate of 2.8% sits at the 73rd percentile of the headings in chapter 84.
