Analysis
HTS 2941.10.50 covers other: other under heading 2941 (antibiotics).
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 2941.10.10 (ampicillin and its salts, duty-free), 2941.10.20 (penicillin G salts, duty-free) and 2941.10.30 (carfecillin, sodium; Cloxacillin, sodium; Dicloxacillin…, duty-free).
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 3 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.
