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.

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 morpholine component is the primary functional compound and the product is not a true salt
Morpholine derivatives are classified under heterocyclic compounds with nitrogen hetero-atoms.
If the product is a mixture of diethanolamine and morpholine rather than a defined salt
Mixtures of chemicals not meeting the definition of a single compound are classified as chemical products.
If the salt is not specifically covered by the diethanolamine subheading
Other amino-alcohol salts may fall under the residual subheading for amino-alcohols.

Import Tips & Compliance
• Confirm the exact stoichiometry of the salt and whether it contains free morpholine, which could affect classification
• Ensure the product is not a mixture of separate salts, as that would change the tariff classification
• Consult a customs broker familiar with Chapter 29 chemical classification rules
