Hexamethylenediamine Adipate Salt
Hexamethylenediamine adipate salt is a 1:1 salt formed from hexamethylenediamine and adipic acid, classified under HTS 2921.22.1000 because it is derived in whole or in part from adipic acid. This compound serves as a key intermediate in nylon 6,6 polymer production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not derived from adipic acid
Pure hexamethylenediamine or salts from other acids fall under the 'other' subheading without adipic acid specification.
If polymerized into nylon salt
Polymerized forms like nylon 6,6 salt are classified as polyamide resins in Chapter 39 rather than amine compounds.
If in mixed chemical preparations
Solutions or mixtures with solvents/additives for specific uses move to Chapter 38 as chemical preparations.

Import Tips & Compliance
• Provide detailed chemical analysis certificates confirming adipic acid derivation to avoid reclassification
• Ensure proper UN-approved packaging for corrosive amine salts to comply with DOT and IMDG regulations
• Declare exact purity levels (typically >98%) as impurities may affect duty treatment under chapter notes
