Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as unground pebbles
Pebble form without grinding remains under unground natural phosphates in 2510.10.
If purified to dicalcium phosphate
High-purity extractions become chemical phosphates under Chapter 28, not raw minerals.
If when granulated for direct fertilizer application
Granulation or further processing into goods of heading 3105 shifts it to fertilizers.
