Analysis
HTS 2941.20.50 covers streptomycins and their derivatives; salts thereof: other under heading 2941 (antibiotics).
Neighbouring lines carry rates from duty-free to 3.5%, so the exact line matters. The widest gap is with 2941.20.10 (dihydrostreptomycin and its derivatives; salts thereof), at 3.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 3.5 percentage points.
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.
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. That is the industry code a US manufacturer of the same product would normally use.
