Diethanolamine Morpholine Salt from Japan
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.

Import Tips
• 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
