Phosphate Fertilizers

The merchandise covered by these orders is phosphate fertilizers in all physical forms (i.e., solid or liquid form), with or without coating or additives such as anti-caking agents. Phosphate fertilizers in solid form are covered whether granular, prilled (i.e., pelletized), or in other solid form (e.g., powdered). The covered merchandise includes phosphate fertilizers in the following forms: ammonium dihydrogenorthophosphate or monoammonium phosphate (MAP), chemical formula NH4H2PO4; diammonium hydrogenorthophosphate or diammonium phosphate (DAP), chemical formula (NH4)2HPO4; normal superphosphate (NSP), also known as ordinary superphosphate or single superphosphate, chemical formula Ca(H2PO4)2-CaSO4; concentrated superphosphate, also known as double, treble, or triple superphosphate (TSP), chemical formula Ca(H2PO4)2-H2O; and proprietary formulations of MAP, DAP, NSP, and TSP. The covered merchandise also includes other fertilizer formulations incorporating phosphorous and non-phosphorous plant nutrient components, whether chemically-bonded, granulated (e.g., when multiple components are incorporated into granules through, e.g., a slurry process), or compounded (e.g., when multiple components are compacted together under high pressure), including nitrogen, phosphate, sulfur (NPS) fertilizers, nitrogen, phosphorous, potassium (NPK) fertilizers, nitric phosphate (also known as nitrophosphate) fertilizers, ammoniated superphosphate fertilizers, and proprietary formulations thereof that may or may not include other nonphosphorous plant nutrient components. For phosphate fertilizers that contain non-phosphorous plant nutrient components, such as nitrogen, potassium, sulfur, zinc, or other non-phosphorous components, the entire article is covered, including the non-phosphorous content, provided that the phosphorous content (measured by available diphosphorous pentaoxide, chemical formula P2O5) is at least 5% by actual weight. Phosphate fertilizers that are otherwise subject to these orders are included when commingled (i.e., mixed or blended) with phosphate fertilizers from sources not subject to these orders. Phosphate fertilizers that are otherwise subject to these orders are included when commingled with substances other than phosphate fertilizers subject to these orders (e.g., granules containing only non-phosphate fertilizers such as potash or urea). Only the subject component of such commingled products is covered by the scope of these orders. The following products are specifically excluded from the scope of these orders: (1) ABC dry chemical powder preparations for fire extinguishers containing MAP or DAP in powdered form; (2) industrial or technical grade MAP in white crystalline form with available P2O5 content of at least 60% by actual weight; (3) industrial or technical grade diammonium phosphate in white crystalline form with available P2O5 content of at least 50% by actual weight; (4) liquid ammonium polyphosphate fertilizers; (5) dicalcium phosphate, chemical formula CaHPO4; (6) monocalcium phosphate, chemical formula CaH4P2O8; (7) trisodium phosphate, chemical formula Na3PO4; (8) sodium tripolyphosphate, chemical formula Na5P3O10; (9) prepared baking powders containing sodium bicarbonate and any form of phosphate; (10) animal or vegetable fertilizers not containing phosphate fertilizers otherwise covered by the scope of these orders; (11) phosphoric acid, chemical formula H3PO4.
