Product classification
HS code for Tilidine: 2922.44
Amino-acids, other than those containing more than one kind of oxygen function, and their esters, tilidine (INN) and its esters, salts thereof.
Classification of tilidine under HS 2922.44
Tilidine is an organic chemical compound classified under HS code 2922.44. This classification is based on its chemical structure as an amino-acid containing only one kind of oxygen function (the carboxylic group and its esters). Specifically, Tilidine (INN) and its esters and salts are explicitly named in the 2922.44 subheading. As a synthetic opioid analgesic, it falls under Chapter 29, which covers organic chemicals. The classification follows the rules for oxygen-function amino-compounds. Because Tilidine is a defined chemical individual, it is placed in Chapter 29 rather than Chapter 30, provided it is not yet prepared as a medicament in measured doses or in forms or packings for retail sale. The inclusion of the (INN) designation in the HS description indicates that this code is internationally standardized for this specific pharmaceutical substance to facilitate monitoring and control of trade.

Codes often confused with 2922.44
Common mistake. Tilidine is frequently misclassified under HS code 3004.90, which covers medicaments consisting of mixed or unmixed products for therapeutic uses, put up in measured doses. If the Tilidine is in the form of tablets, capsules, or drops ready for patient use, 3004.90 is correct; however, the bulk chemical substance must be in 2922.44. It is also sometimes confused with 2922.49, the residual category for other amino-acids, but since Tilidine is specifically named in 2922.44, that code takes precedence.
Top exporters and importers of HS 292244 (the code used for tilidine), 2025
In 2025, the largest exporter of HS 292244 (the code used for tilidine) in UN Comtrade data was Germany, with 87% of world exports; the largest importer in UN Comtrade data was Serbia, with 94% 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).
