HEADING

2917

CHAPTER

In plain English

This category covers various organic acids and related compounds, including their anhydrides, halides, peroxides, and derivatives that have been modified by halogenation, sulfonation, nitration, or nitrosation. The items are grouped based on whether the acid structure is open-chain, ring-shaped, or aromatic. Specific subcategories identify particular substances such as oxalic, adipic, azelaic, sebacic, maleic, phthalic, and terephthalic acids, along with their salts, esters, and other specific forms.

Chapter 29 classification notes

Key chapter for pharmaceutical intermediates, narcotic and psychotropic substances (controlled under the 1961 and 1971 UN Conventions), and list-1 chemicals under the 1988 Convention (drug-precursor control). Import requires prior authorisation from the national competent authority.
