Heading 2937 covers hormones, prostaglandins, thromboxanes and leukotrienes, natural or reproduced by synthesis; derivatives and structural analogues thereof, including chain modified polypeptides, used primarily as hormones. It splits into 3 six-digit subheadings and 5 US tariff lines, 5 of which are duty-free under the general rate.
Headings are the four-digit level of the Harmonized System — the layer that is identical across all 160-plus countries that use it. The six-digit subheading is also international; the last two digits of each code here are US-specific and do not carry across to another country's tariff.
