Analysis
HTS 2936.29.50 covers other: other under heading 2936 (provitamins and vitamins, natural or reproduced by synthesis (including natural…). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.
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 2936.29.10 (other vitamins and their derivatives: folic acid, duty-free), 2936.29.16 (niacin and niacinamide, duty-free) and 2936.29.20 (aromatic or modified aromatic, 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 concordance is how imports of this line are compared with US output.
