Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by imine or amine function over amide
Subchapter rules prioritize the principal function; imine-function compounds classified later take precedence.
If it's a human blood serum or vaccine product containing the compound
Immunological products containing organic compounds shift to Chapter 30 per exclusions.
If imported as chemical mixture or preparation exceeding 0.5% concentration
Prepared chemical mixtures/binders fall under 3824, not pure compounds of Chapter 29.
