HS code for Heparin: 3001.90
Glands and other organs, heparin and its salts, other human or animal substances prepared for therapeutic or prophylactic uses, n.e.c. in heading 3001.
Classification of heparin under HS 3001.90
Heparin and its salts are classified under HS code 3001.90. This classification is based on the product's biological origin and its primary therapeutic application. Chapter 30 covers pharmaceutical products, and heading 3001 specifically includes glands and other organs for organo-therapeutic uses, as well as heparin and its salts. Heparin is a highly sulfated glycosaminoglycan extracted from animal tissues, most commonly porcine intestinal mucosa or bovine lungs. The Harmonized System treats heparin as a distinct entity within heading 3001 because of its biological source and its critical role as an anticoagulant. Subheading 3001.90 is the residual category for other substances of human or animal origin prepared for therapeutic or prophylactic uses. This classification is appropriate for heparin in its bulk form or as a raw material. If the heparin is prepared in measured doses, such as pre-filled syringes, or put up in forms or packings for retail sale, it would generally be classified under heading 3004. However, for the substance itself and its various salts (like heparin sodium or heparin calcium), 3001.90 is the correct designation according to GIR 1 and the specific text of the heading.

Codes often confused with 3001.90
Common mistake. Heparin is often misclassified under HS code 3004.90. While 3004.90 covers medicaments for retail sale, 3001.90 is the correct code for the bulk substance. Another error is attempting to classify it under 2916 or 2942 as a pure organic chemical. Because heparin is a complex biological polymer derived from animal tissue, Chapter 30 is more specific than Chapter 29. Additionally, it should not be confused with 3822, which is for diagnostic or laboratory reagents.
Top exporters and importers of HS 300190 (the code used for heparin), 2025
In 2025, the largest exporter of HS 300190 (the code used for heparin) in UN Comtrade data was China, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
