2939 - Alkaloids, natural or reproduced by synthesis, and their salts, ethers, esters and other derivatives:

Sub-classifications

Commodity Code
Description

Overview

This HTS category, 2939, encompasses a wide array of alkaloids, which are naturally occurring organic compounds, often basic, and typically found in plants. It also includes synthetic counterparts of these alkaloids, as well as their various salts, ethers, esters, and other chemical derivatives. These substances are frequently utilized in pharmaceuticals, as chemical intermediates, or for other specialized industrial applications due to their unique chemical structures and biological activities.

As a category within Chapter 29 (Organic Chemicals), 2939 is distinct from other chapters that might cover live animals (Chapter 01) or minerals, which are found at the same top level of the HTS. Within Chapter 29, this category focuses specifically on alkaloids and their related compounds, differentiating them from other organic chemical families such as alcohols, aldehydes, or hydrocarbons.

Category 2939 is further subdivided to classify alkaloids based on their origin or specific chemical identity. These subcategories allow for precise classification of various alkaloid groups, including those derived from opium, cinchona, ephedra, and rye ergot. Separate provisions are made for caffeine and its salts, as well as for theophylline and aminophylline derivatives. The "Other" subheading serves as a residual category for alkaloids and their derivatives not specifically enumerated elsewhere within this chapter, requiring careful analysis of their chemical structure and origin.
