Product classification
HS code for Fentanyl derivatives: 2933.34
Heterocyclic compounds, containing an unfused pyridine ring (whether or not hydrogenated) in the structure, other fentanyls and their derivatives.
Classification of fentanyl derivatives under HS 2933.34
Fentanyl derivatives containing an unfused pyridine ring in their chemical structure are classified under HS code 2933.34. This classification is situated within Heading 2933, which covers heterocyclic compounds containing only nitrogen hetero-atom(s). The specific subheading 2933.34 was created as part of the 2022 HS updates to provide a dedicated code for fentanyl analogs that possess a pyridine ring structure that is not fused to another ring. This distinction is vital for the implementation of the International Convention on the Harmonized Commodity Description and Coding System. The classification process involves a detailed analysis of the molecular structure to determine the presence of the unfused pyridine ring. Because these substances are often used as precursors or are themselves potent narcotics, accurate classification under 2933.34 is essential for legal compliance and to avoid the severe penalties associated with the misdeclaration of controlled substances. This code allows for precise tracking of specific chemical variations of the fentanyl molecule.

Codes often confused with 2933.34
Common mistake. These derivatives are most commonly confused with HS code 2934.92. The distinction depends entirely on the chemical structure: 2933.34 is for nitrogen-only heterocyclic rings (pyridine), while 2934.92 is for compounds containing other hetero-atoms like oxygen or sulfur. Misclassification between these two can lead to significant regulatory delays.
Top exporters and importers of HS 293334 (the code used for fentanyl derivatives), 2025
In 2025, the largest exporter of HS 293334 (the code used for fentanyl derivatives) in UN Comtrade data was India, with 54% of world exports; the largest importer in UN Comtrade data was Algeria, with about 64% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).

Questions about fentanyl derivatives
What is the HS code for Fentanyl derivatives?
The HS code for Fentanyl derivatives is 293334 (Heterocyclic compounds; containing an unfused pyridine ring (whether or not hydrogenated) in the structure, other fentanyls and their derivatives). Fentanyl derivatives containing an unfused pyridine ring are classified under HS code 2933.34.
How do I classify Fentanyl derivatives for customs?
Fentanyl derivatives is classified under HS code 293334 — Heterocyclic compounds; containing an unfused pyridine ring (whether or not hydrogenated) in the structure, other fentanyls and their derivatives. This is a 6-digit subheading level code.
How do I distinguish between 2933.34 and 2934.92?
Classification depends on the molecular structure; 2933.34 is used when the compound contains only nitrogen hetero-atoms in an unfused pyridine ring.
Which countries are the top exporters of fentanyl derivatives (HS 293334)?
In 2025, the top exporters of HS 293334 (the code used for fentanyl derivatives) in UN Comtrade data were India ($1.8M, 54% of world exports), France ($1.4M) and Poland ($49K). World exports came to about $3.4M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of fentanyl derivatives (HS 293334)?
In 2025, the top importers of HS 293334 (the code used for fentanyl derivatives) in UN Comtrade data were Algeria (about $1.4M, 64% of world imports), Australia ($198K) and Lithuania ($184K). World imports came to about $2.2M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
