HS Code 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
HS code 2922.44 is the 6-digit subheading for amino-acids, other than those containing more than one kind of oxygen function, and their esters, tilidine (INN) and its esters, salts thereof. It is used for tilidine Hydrochloride, tilidine Phosphate, tilidine Base, tilidine Ethyl Ester and tilidine Methyl Ester.
What HS 2922.44 covers
This HS code is highly specific, covering tilidine (INN), a synthetic opioid analgesic, along with its esters and salts, provided they do not contain more than one type of oxygen function. Due to its pharmacological properties as a potent pain reliever, tilidine is a controlled substance in many countries, subject to strict international and national regulations concerning its manufacture, trade, and distribution. In international trade, importers are exclusively pharmaceutical companies or authorized distributors in countries where tilidine is approved for medical use. Exporters are typically pharmaceutical manufacturers holding licenses for controlled substances. Key considerations for trade are paramount: stringent regulatory compliance, secure transportation, detailed documentation, and adherence to quotas and international conventions like the UN Single Convention on Narcotic Drugs. The trade volume is tightly controlled and driven solely by medical demand for pain management, making it a highly specialized and regulated segment of the chemical trade with limited global players.

Codes often confused with 2922.44
Common mistake. This code is very specific to tilidine, making misclassification with other amino acids in 292249 unlikely, unless the substance is incorrectly identified. It could be confused with other opioid analgesics under different HS codes if the chemical structure is not precisely verified.

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).
