Chapter 25

Mineral products

Chapter 25 of the Harmonized Tariff Schedule sits in section V (mineral products). It has 29 headings and 79 eight-digit tariff lines.

71 of its 78 lines with a percentage rate are duty-free at the general rate (91%) and 7 are dutiable, from duty-free up to 3%. The median line pays duty-free.

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 most finely divided heading is 2508 (other clays (not including expanded clays of heading 6806), andalusite, kyanite…), with 6 lines; fine division usually means the rates or the trade statistics differ enough to be worth separating.

24 of its 29 headings are entirely duty-free at the general rate, including 2501 (salt (including table salt and denatured…), 2502 (unroasted iron pyrites) and 2503 (sulfur of all kinds, other than sublimed…).

The heading with the highest median rate is 2516 (granite, porphyry, basalt, sandstone and other monumental or building stone…) at 2.8%.
