2922.12.00.01 - Diethanolamine and its salts

This HTS category, 2922.12.00.01, specifically covers Diethanolamine and its salts. Diethanolamine is an organic compound belonging to the amino-alcohol family, characterized by the presence of two hydroxyl (-OH) groups and one amino (-NH2) group attached to an ethyl backbone. Its salts are formed when the amine group reacts with an acid. These compounds find widespread use as intermediates in the synthesis of various industrial chemicals, including surfactants, textiles, pharmaceuticals, and corrosion inhibitors.

To distinguish this category from its siblings, it's important to note the number of ethanolamine groups present. While 2922.11.00.00 covers Monoethanolamine (one ethanolamine group), and 2922.15.00.00 covers Triethanolamine (three ethanolamine groups), this heading exclusively addresses compounds with precisely two such groups, Diethanolamine. Other siblings like 2922.14.00.00 and 2922.16.00.00 cover entirely different chemical structures and specific compounds with distinct classifications.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification under 2922.12.00.01 is determined solely by the identity of the chemical substance as either Diethanolamine or its salts. The focus for classification professionals will be on verifying the chemical composition and ensuring the product is not classifiable under a more general or a more specific heading based on its precise chemical structure and intended use if that significantly alters its primary function beyond being an amino-alcohol.
