Overview

Chapter 29 of the Harmonized Tariff Schedule (HTS) details a wide array of organic chemicals. Within this chapter, heading 2922 specifically encompasses a diverse group of compounds characterized by the presence of both amino (-NH2 or substituted amino groups) and oxygen-containing functional groups. This classification is crucial for distinguishing these nitrogen- and oxygen-bearing organic molecules from other broad chemical categories.

Unlike sibling categories at the same four-digit level, which might cover different classes of organic compounds such as aldehydes, ketones, or carboxylic acids (e.g., heading 2912 for aldehydes or heading 2915 for saturated acyclic monocarboxylic acids), heading 2922 focuses exclusively on compounds that possess both an amino group and at least one oxygen function, such as hydroxyl (-OH), ether (-O-), ester (-COO-), or carbonyl (C=O) groups. The presence of both functionalities is the defining characteristic for classification under this heading.

The subcategories within heading 2922 further refine the classification based on the specific types of oxygen-containing functions and the overall structure of the amino compound. These subdivisions differentiate between amino-alcohols, amino-phenols, amino-aldehydes, amino-ketones, and amino-acids, along with their respective ethers and esters, and salts. The final subcategory, 2922.50, consolidates amino-compounds that combine multiple oxygen functions with phenolic or alcoholic groups, offering a more specific placement for these complex molecules.
