More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is the free amine rather than the salt
The free base diethanolamine is classified under the residual amino-alcohol subheading.
If the product is classified as an acetate salt of an organic base
Acetates of organic bases could be classified under carboxylic acid salts, though note 5(C)(2) prioritizes the base.
If the product is put up in measured doses or for retail sale as a medicament
Medicaments put up for retail sale are classified in Chapter 30, overriding the chemical classification.

• Check if the product qualifies for duty relief under tariff rate provisions for pharmaceutical ingredients
Related Products under Tariff item 2922.12.00
Diethanolamine 99% Technical Grade
Technical grade diethanolamine at 99% purity, a clear viscous liquid used as an intermediate in emulsifiers, gas treating, and surfactants. It is a separate chemically defined organic compound (an amino-alcohol) with no added stabilizers or solvents, qualifying under tariff item 2922.12.00 as diethanolamine.
Diethanolamine Cocamide Salt
Diethanolamine cocamide salt is a chemically defined organic compound formed by the reaction of diethanolamine with coconut fatty acids. It is used as a foaming agent in personal care products such as shampoos and body washes. Under the Customs Tariff, salts of diethanolamine are classified in this tariff item, with the amine component determining the classification.
Diethanolamine (DEA)
Diethanolamine (DEA), a colorless, viscous organic compound with the formula HN(CH₂CH₂OH)₂, used in gas treating, surfactants, and as a chemical intermediate. It is a separate chemically defined amino-alcohol with only hydroxyl oxygen functions, falling under tariff item 2922.12.00 as diethanolamine.
Diethanolamine in Aqueous Solution 85%
Diethanolamine dissolved in water at 85% concentration, a solution that is a normal and necessary method of putting up the product for safe transport. Under Chapter 29 Note 1(d), products dissolved in water are covered by the chapter, and the solution is classifiable as diethanolamine under tariff item 2922.12.00.
Diethanolamine Morpholine Salt
Diethanolamine morpholine salt is a complex salt formed between diethanolamine and morpholine, used in boiler water treatment applications. Under the Customs Tariff, when a salt is formed between two organic compounds, it is classified with the compound that appears last in numerical order in Chapter 29. However, since morpholine is an oxygen-function amino-compound and diethanolamine is the amino-alcohol, the classification follows the amino-alcohol base per the specific subheading.
Diethanolamine Oleate Salt
Diethanolamine oleate salt is formed by the reaction of diethanolamine with oleic acid, creating a chemically defined salt. It is used as an emulsifier in metalworking fluids and industrial lubricants. Under the Customs Tariff, salts of organic bases are classified with the base compound, and since diethanolamine is the amino-alcohol, it falls under this tariff item.
