Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as salts of this compound rather than pure form
Organic salts follow the parent compound per note 3(C)(1), but different subheading applies.
If when pre-diluted in medicinal preparations
Medicinal formulations containing the compound as active/solvent shift to Chapter 30.
If for diagnostic laboratory reagents containing it
Lab reagents put up for specific diagnostic use are classified in 3822.
