HS Code for Theophylline

Theophylline and its derivatives, including aminophylline (theophylline-ethylenediamine), are classified under HS code 2939.59. This code is located within Chapter 29, which covers organic chemicals, and specifically heading 2939, which is dedicated to vegetable alkaloids and their derivatives. Theophylline is a methylxanthine alkaloid used primarily as a bronchodilator in the treatment of respiratory diseases. The classification 2939.59 is a residual category for theophylline-related substances that are not fenetylline (which is specifically assigned to 2939.51). This classification applies to the bulk chemical substance in its pure form or as a salt. It is important to note that this code is for the chemical raw material; once the substance is formulated into a finished dosage form, such as a tablet or an injectable solution for medical use, the classification shifts to Chapter 30.

Common Misclassification

The most common misclassification is 3004.49, which covers medicaments containing alkaloids. If the theophylline is in retail packaging or measured doses, it belongs in Chapter 30. Another error is using 2939.51, which is strictly for fenetylline (INN) and its salts, a regulated stimulant.
