Diphosphorus Pentaoxide Anhydride P2O5
Diphosphorus pentaoxide (P2O5), also known as phosphorus pentoxide, is a white, deliquescent powder used primarily as a dehydrating and drying agent in chemical synthesis. It reacts with water to form phosphoric acid, making it essential for producing high-purity phosphates and in organic reactions requiring anhydrous conditions. This chemically defined inorganic compound is specifically classified under HTS 2809.10.00.00 as diphosphorus pentaoxide.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dissolved or reacted with water during production
Hydrated forms become phosphoric acid, classified under heading 2811 for oxides/acids of nonmetals like phosphorus.
If mixed with organic stabilizers or formulated as a commercial preparation
Mixtures or preparations not chemically defined fall under Chapter 38 as chemical products not elsewhere specified.
If imported as a metal phosphate salt derived from P2O5
Phosphates and polyphosphates of nonmetals are classified under heading 2835, not the pure oxide.
