HS Code for Methadone

Methadone is classified under HS code 2922.39. This classification is part of the group for oxygen-function amino-compounds, specifically amino-aldehydes, amino-ketones, and amino-quinones. Methadone is a synthetic opioid that contains both an amine group and a ketone group within its molecular structure. Under the Harmonized System, Chapter 29 covers organic chemicals, and Heading 2922 is dedicated to amino-compounds with oxygen functions. While the specific subheading 2922.31 is often designated for certain INN substances like Amfepramone and Methadone in many versions of the tariff, the "Other" category 2922.39 is used for related salts, derivatives, or specific chemical variations not explicitly named in the preceding subheadings. The classification depends on the chemical identity as an amino-ketone that does not contain more than one kind of oxygen function (i.e., it contains only the amine and the ketone/aldehyde/quinone function).

Products Included

• Methadone (INN)
• Methadone hydrochloride
• Salts of methadone
• Methadone intermediates (specific amino-ketone forms)
• Isomethadone

Common Misclassification

Methadone is often misclassified under HS code 2933, which covers heterocyclic compounds with nitrogen hetero-atom(s) only. However, because methadone's nitrogen is part of an open chain (acyclic) rather than a ring, it belongs in 2922. It is also frequently confused with HS code 3004 if it is prepared as a finished pharmaceutical (e.g., oral solution or tablets). If the product is the bulk active pharmaceutical ingredient (API), it must be classified in Chapter 29, not Chapter 30.

FAQ

What is the HS code for Methadone?

Methadone and its salts are generally classified under 2922.31 or 2922.39, depending on the specific national tariff schedule and the purity of the compound.

Why is Methadone in Chapter 29 and not Chapter 30?

Chapter 29 is for separate chemically defined compounds (bulk chemicals). Chapter 30 is for medicaments that have been mixed or put up in dosage forms for therapeutic use.
