2937.29.90

Analysis

HTS 2937.29.90 covers other: other under heading 2937 (hormones, prostaglandins, thromboxanes and leukotrienes, natural or reproduced by…). US Customs collects import statistics for it under 5 ten-digit suffixes, reported in g.

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 ten-digit suffixes separate salts and esters of hydrocortisone, salts and esters of prednisone, salts and esters of prednisolone and anabolic agents and androgens. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.

Census statistics map these goods to NAICS 325412 (Pharmaceutical Preparation Manufacturing), an industry of 1,436 US establishments employing 170,029 people. That concordance is how imports of this line are compared with US output.
