Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If water content >70% or contains pH adjusters
Excessive dilution or additives make it a formulated chemical preparation, not a Chapter 29 solution.
If anhydrous form stabilized with alcohol cosolvent
Alcohol-containing stabilizers may classify under amine-alcohol mixtures of 2903.
