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.

Import Tips & Compliance
• Document exact EDA concentration (wt%) to qualify under Chapter 29 note (d) aqueous solution provision
• Ship as UN 1761 (corrosive solution) in IBC totes or drums with secondary containment per CFR 173.242
• Avoid stabilizer additions that trigger note (f) review or shift to mixtures of 3824
