Chapter 31
Products of the chemical or allied industries
Chapter 31 of the Harmonized Tariff Schedule sits in section VI (products of the chemical or allied industries). It has 5 headings and 24 eight-digit tariff lines.
Every one of its 24 tariff lines is duty-free at the general rate, so classification within the chapter affects statistics and Chapter 99 measures rather than the base duty.
The most finely divided heading is 3102 (mineral or chemical fertilizers, nitrogenous), with 9 lines; fine division usually means the rates or the trade statistics differ enough to be worth separating.
Its headings are 3101 (animal or vegetable fertilizers…), 3102 (mineral or chemical fertilizers…), 3103 (mineral or chemical fertilizers…), 3104 (mineral or chemical fertilizers…) and 3105 (mineral or chemical fertilizers…).
