Hexamethylenediamine Adipate Salt
Hexamethylenediamine adipate, also known as nylon 6,6 salt, is the salt formed from hexamethylenediamine and adipic acid. It falls under HTS 2921.22.5000 as a derivative salt of hexamethylenediamine, an acyclic polyamine. This compound is primarily used as an intermediate in nylon 6,6 polymer production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by the acid component
Salts are classified with the organic base (amine) occurring later in Chapter 29 per classification notes.
If polymerized into nylon 6,6
Polymerized forms become polyamide resins under Chapter 39, not Chapter 29 monomers.
If imported as aqueous solution > specific use
Solutions only qualify under Chapter 29 if for safety/transport without specific use adaptation.

Import Tips & Compliance
• Provide detailed chemical analysis certificates confirming it's a hexamethylenediamine salt to avoid misclassification as polymers
• Ensure SDS and purity documentation (typically >98%) for customs valuation and safety compliance
• Verify packaging meets UN standards for corrosive amines to prevent shipping delays
