Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If concentration too dilute
Excessive dilution becomes chemical mixture outside chapter 29 scope.
If for different amine solution
Methylamine aqueous solutions use earlier alkylamine subheadings.
If other dissolved chemicals
Different inorganic solvents may shift to later miscellaneous chemical heading.

Import Tips & Compliance
• Specify exact concentration; solutions >50% water may challenge 'dissolved' status
• Test for solvent suitability; water dilution permitted without specific use implication
• Use UN-approved chemical solution packaging for hazardous liquid classification
