Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily as phosphate salt
Chapter 28 takes precedence for simple inorganic phosphates over organic salts.
If nitrogen function dominates classification
Note 4 requires latest numerical heading, but ester function prevails over nitrogen.
If stabilized aqueous preparation
Aqueous solutions beyond Chapter 29 note (d) limits become preparations.

Import Tips & Compliance
• Include salt formation certificate linking to parent phosphoric ester classification
• Water content analysis required; excessive moisture may trigger aqueous solution exclusion
• Hazard labeling mandatory due to organophosphate salt irritancy properties
