Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for constituent hexamethylenediamine if separated
The free base polyamine would classify under earlier 2903 heading, but formed salt takes later 2921 amine-function classification per Chapter note on salts.
If adipic acid esters rather than salt
Chapter notes specify esters follow the later-occurring acid-function compound, distinguishing from simple carboxylate salts in amine headings.
If modified with enzymatic stabilizers
Enzyme-containing preparations excluded from Chapter 29 per note (h), but standard nylon salt without enzymes stays classified here.
