Products classified under HTS 2510.10.00.00
Unground Florida Pebble Phosphate Rock
Natural calcium phosphate rock mined from Florida deposits, unground and in its raw form with less than 4% magnesium oxide content. Classified under HTS 2510.10.00.00 as unground natural calcium phosphates, suitable for fertilizer production or further processing. It consists primarily of apatite minerals and meets the criteria for unprocessed phosphatic rock.
Raw Moroccan Phosphate Ore
Unground phosphate rock from Moroccan mines, primarily sedimentary apatite with high P2O5 content. Falls under HTS 2510.10.00.00 as natural calcium phosphates in unprocessed, unground form for use in phosphoric acid or fertilizer manufacturing.
Natural Phosphatic Chalk Lumps
Unground lumps of phosphatic chalk, a soft calcareous material containing natural calcium phosphates. HTS 2510.10.00.00 covers this as unground phosphatic chalk, used in soil amendment or animal feed supplements.
Tennessee Brown Rock Phosphate
