Analysis
HTS 2941.90.10 covers other: natural under heading 2941 (antibiotics). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.
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.
The other lines in the same group are 2941.90.30 (aromatic or modified aromatic, duty-free) and 2941.90.50 (other: other, duty-free).
Census statistics map these goods to NAICS 325411 (Medicinal and Botanical Manufacturing), an industry of 761 US establishments employing 30,382 people. That is the industry code a US manufacturer of the same product would normally use.
Goods from countries without normal trade relations pay the column 2 rate of 10% instead of nothing, so origin decides between free entry and a 10% duty.
All 2 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
