Product classification
HS code for Fentanyl: 2934.92
Heterocyclic compounds, other fentanyls n.e.c. in 2934, and their derivatives.
Classification of fentanyl under HS 2934.92
Fentanyl and several of its specific derivatives are classified under HS code 2934.92. This classification is part of the 2022 amendments to the Harmonized System nomenclature, which introduced specific subheadings for high-potency synthetic opioids to facilitate better international monitoring. Chapter 29 covers organic chemicals, and Heading 2934 specifically addresses heterocyclic compounds that contain hetero-atoms other than or in addition to nitrogen. Fentanyl and its derivatives classified here typically contain a complex structure that includes oxygen or sulfur atoms within the heterocyclic rings, or they fall into the "other" category of heterocyclic compounds not covered by Heading 2933. The classification is strictly based on the chemical structure of the molecule. Importers and exporters must ensure that the chemical identity matches the requirements of 2934.92, as this code is subject to stringent regulatory oversight by customs authorities and international drug control agencies like the International Narcotics Control Board (INCB).

Codes often confused with 2934.92
Common mistake. Fentanyl was previously often classified under broader codes like 2933.33 or 2934.99. With the 2022 update, 2934.92 is now the mandatory specific code. It is also sometimes misclassified under 3004.40 as a medicament; however, in its pure chemical form or as a raw material, it must be classified in Chapter 29 rather than Chapter 30.
Top exporters and importers of HS 293492 (the code used for fentanyl), 2025
In 2025, the largest exporter of HS 293492 (the code used for fentanyl) in UN Comtrade data was India, with 37% of world exports; the largest importer in UN Comtrade data was the United States, with 49% 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).
