HS Code for Aminophylline

Aminophylline is classified under HS code 2939.59, which is a specific category for theophylline and aminophylline (theophylline-ethylenediamine) and their derivatives, including their salts. This classification is situated within Chapter 29 of the Harmonized System, which covers organic chemicals. Aminophylline is a complex compound composed of theophylline and ethylenediamine in a specific molecular ratio, typically 2:1. It is technically categorized as a vegetable alkaloid, although modern industrial production often involves synthetic processes. According to the General Rules of Interpretation (GRI), specifically GRI 1, the classification is determined by the literal terms of the headings. Since heading 2939 explicitly names aminophylline, it takes precedence over more general chemical headings. The substance is primarily utilized in the pharmaceutical industry as a bronchodilator to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It is important to note that for the product to remain under this code, it must be in its bulk chemical form. If the product is prepared in measured doses or packaged for retail sale as a finished medicament, the classification would shift to Chapter 30.

Products Included

• Bulk Aminophylline powder
• Aminophylline hydrates
• Theophylline-ethylenediamine compounds
• Salts of aminophylline
• Aminophylline derivatives (excluding fenetylline)

Common Misclassification

Aminophylline is frequently confused with HS code 2939.51, which is reserved specifically for fenetylline (INN) and its salts. Another common error is classifying bulk aminophylline under HS code 3004.20 or 3004.90. These codes are for medicaments consisting of mixed or unmixed products for therapeutic uses, put up in measured doses or for retail sale. If the substance is a raw chemical material, it must stay in Chapter 29.
