Analysis
HTS 2903.19.30 covers sec-Butyl chloride under heading 2903 (halogenated derivatives of hydrocarbons).
Rates on the nearby lines range from 3.7% to 5.5%. The costliest confusion would be with 2903.19.60 (other: other) at 5.5%, a difference of 5.5 points on the customs value.
Goods from countries without normal trade relations pay the column 2 rate of 114.5% instead of nothing, so origin decides between free entry and a 114.5% 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 2903.19.05 (1,2-Dichloropropane (Propylene dichloride) and…, 5.1%), 2903.19.10 (hexachloroethane and tetrachloroethane, 3.7%) and 2903.19.60 (other: other, 5.5%).
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.
