Analysis
HTS 2921.13.00 covers 2-(N,N-Diethylamino)ethyl chloride hydrochloride under heading 2921 (amine-function compounds).
Neighbouring lines carry rates from duty-free to 6.5%, so the exact line matters. The widest gap is with 2921.44.70 (other: other), at 6.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 6.5 percentage points.
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.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 26% of the 1050 tariff lines in chapter 29. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Census statistics map these goods to NAICS 325199 (All Other Basic Organic Chemical Manufacturing), an industry of 894 US establishments employing 77,304 people. That is the industry code a US manufacturer of the same product would normally use.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
