2934 - Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds:

Sub-classifications

Commodity Code
Description

Overview

Category 2934 encompasses a diverse group of organic chemicals, specifically nucleic acids and their salts, alongside other heterocyclic compounds. Nucleic acids, essential components of genetic material, and their synthesized or naturally derived salts fall under this heading. The latter part of the description covers a broad range of heterocyclic compounds – organic molecules containing ring structures with at least one atom that is not carbon. This includes compounds with nitrogen, oxygen, or sulfur within the ring.

Unlike other major Chapters within Section VI (e.g., Chapter 28 covering inorganic chemicals, or Chapters 30-38 covering specialized products), Chapter 29 exclusively deals with organic chemicals. Within Chapter 29, 2934 occupies a distinct position by focusing on the complex structures of nucleic acids and a wide array of heterocyclic compounds, rather than simpler organic molecules covered in other headings like alcohols, aldehydes, or acids. This category serves as a catch-all for heterocyclic compounds not specifically enumerated in more specialized headings within Chapter 29.

To further refine classification, the subcategories within 2934 break down the broader group of heterocyclic compounds based on specific ring systems. These include compounds featuring unfused thiazole rings (2934.10), benzothiazole ring systems (2934.20), and phenothiazine ring systems (2934.30), all of which are distinct chemical structures with different properties and applications. The residual "Other" category is reserved for any heterocyclic compounds that do not fit into these specific subheadings, ensuring comprehensive coverage of these complex organic molecules.
