Analysis
HTS 2941.90.50 covers other: other under heading 2941 (antibiotics). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.
For statistics it divides in two: 2941.90.50.30 for clindamycin (INN) and its salts and 2941.90.50.90 for other. Both pay the same duty; the suffix records which kind was imported.
The normal trade relations rate here is zero, shared by about 26% of the 1050 tariff lines in chapter 29, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
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.
The other lines in the same group are 2941.90.10 (other: natural, duty-free) and 2941.90.30 (aromatic or modified aromatic, duty-free).
All 2 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
