Triethanolamine Sulfate
Triethanolamine sulfate is a salt derived from triethanolamine and sulfuric acid, used primarily as an emulsifier in personal care products and textiles. Classified under HTS 2922.19.90.00 as it matches the definition of salts of triethanolamine, an oxygen-function amino-alcohol, per HTS chapter notes on salt classification. Its chemical structure retains the core amino-alcohol functionality.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nitrated or with nitrogen functions beyond amino-alcohol
Per note 4, nitro/nitroso derivatives shift to heading 2929, later in numerical order.
If disodium salt form for industrial phosphate replacement
Complex salts with inorganic components may classify under Chapter 28 disulfates if not purely organic per note 5.
If surface-active preparations containing >10% this salt
Formulations as soaps/surfactants exclude from Chapter 29 per note 2(k), moving to Chapter 34.
