HS Code 2933.34 – Heterocyclic compounds; containing an unfused pyridine ring (whether or not hydrogenated) in the structure, other fentanyls and their derivatives
HS code 2933.34 is the 6-digit subheading for heterocyclic compounds, containing an unfused pyridine ring (whether or not hydrogenated) in the structure, other fentanyls and their derivatives. It is used for carfentanil, sufentanil, alfentanil, remifentanil and fentanyl citrate.
What HS 2933.34 covers
This HS code encompasses various fentanyl derivatives and related heterocyclic compounds featuring an unfused pyridine ring. In international trade, these substances are highly controlled due to their potent opioid properties and significant potential for abuse. Legitimate trade is primarily conducted by licensed pharmaceutical manufacturers for the production of powerful analgesics and anesthetics, as well as by specialized research institutions for scientific study. Key things to know include the stringent regulatory frameworks imposed by international drug control conventions, requiring meticulous documentation, permits, and secure transportation. Illicit trade in these compounds is a major global concern, leading to severe penalties for unauthorized handling. Countries with advanced pharmaceutical industries and robust regulatory bodies are typically the main players in their legitimate import and export, ensuring strict adherence to medical and scientific applications.

Codes often confused with 2933.34
Common mistake. This code can be confused with other opioid analgesics under HS 2939.11 (morphine) or 2939.19 (other opium alkaloids) if the specific chemical structure is not carefully identified, as the pyridine ring is a key differentiator.
Top exporters and importers of HS code 293334, 2025

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).
