Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by amine function without oxygen-acid emphasis
Chapter notes prioritize last numerical heading; amine compounds in 2921 could apply if oxygen function not dominant per 2922 definitions.
If diluted for immunological or diagnostic research use
Chapter 29 excludes immunological products of 3002; tilidine derivatives in research sera shift to Chapter 30.
