Analysis
HTS 2921.19.31 covers 3-Amino-3-methyl-1-butyne; (Dimethylamino)isopropyl chloride hydrochloride under heading 2921 (amine-function compounds).
Rates on the nearby lines range from 3.7% to 6.5%. The costliest confusion would be with 2921.19.61 (other: other) at 6.5%, a difference of 6.5 points on the customs value.
Goods from countries without normal trade relations pay the column 2 rate of 30.5% instead of nothing, so origin decides between free entry and a 30.5% duty.
There is no general-rate duty on this line, which puts it with roughly 26% of the 1050 tariff lines in chapter 29 that are also free. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
The other lines in the same group are 2921.19.11 (mono-, di- and triethylamines;mono-, di-, and tri-(propyl-…, 3.7%) and 2921.19.61 (other: other, 6.5%).
Census statistics map these goods to NAICS 325199 (All Other Basic Organic Chemical Manufacturing), an industry of 894 US establishments employing 77,304 people, the industry a domestic producer of these goods reports under.
