Phosphorus Pentoxide from Germany
Phosphorus pentoxide (P4O10), also known as phosphoric anhydride, is a white, highly hygroscopic powder used primarily as a desiccant and dehydrating agent in chemical synthesis. As a chemically defined inorganic oxygen compound of the non-metal phosphorus, it falls under tariff item 2811.29.00 for other inorganic oxygen compounds of non-metals. It is not excluded by Chapter 28 notes and is not a metal salt, so it is correctly classified here.

Import Tips
• Ensure the product is pure and not mixed with organic substances, as that could shift classification
• Declare the correct end-use (desiccant or dehydrating agent) to the CBSA to avoid reclassification
• Verify whether the shipment requires a permit under the Export and Import Permits Act if the phosphorus content triggers controls
