Analysis
HTS 3004.43.00 covers containing norephedrine or its salts under heading 3004 (medicaments (excluding goods of heading 3002, 3005 or 3006) consisting of mixed or…).
There is no general-rate duty on this line, which puts it with roughly 93% of the 58 tariff lines in chapter 30 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Goods from countries without normal trade relations pay the column 2 rate of 25% instead of nothing, so origin decides between free entry and a 25% duty.
Census statistics map these goods to NAICS 325412 (Pharmaceutical Preparation Manufacturing), an industry of 1,436 US establishments employing 170,029 people, the industry a domestic producer of these goods reports under.
All 17 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
