Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity <98% or contains significant impurities
Only specifically named compounds with high purity qualify for 2933.99.85; others go to basket provision.
If pre-mixed with pharmaceutical excipients
Mixtures for pharmaceutical use shift to Chapter 30 as organo-therapeutic preparations.
If erroneous classification ignoring heterocyclic nature
Must recognize nitrogen hetero-atom structure for proper Chapter 29, Subchapter placement over acyclic hydrocarbons.
