Analysis
HTS 2937.22.00 covers halogenated derivatives of adrenal cortical hormones under heading 2937 (hormones, prostaglandins, thromboxanes and leukotrienes, natural or reproduced by…). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in g.
For statistics it divides in two: 2937.22.00.10 for dexamethasone (INN) and its salts and 2937.22.00.90 for other. Both pay the same duty; the suffix records which kind was imported.
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.
All 16 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
