U.S. imports of monoammonium phosphate (map) fertilizers & dap-map mixtures (SITC 56294) totaled $57.4M in July 2026, traded with 23 countries.
Importers of Monoammonium Phosphate (MAP) Fertilizers & DAP-MAP Mixtures paid $80K in duties in July 2026 — an effective duty rate of 24% on $333K in dutiable value, based on actual customs collections rather than the published tariff schedule. Monoammonium Phosphate (MAP) Fertilizers & DAP-MAP Mixtures imports of $57.4M in July 2026 ran 52% above the year-to-date monthly average of $37.8M.
Last updated: July 2026 dataMonoammonium phosphate (MAP) and its mixtures with diammonium phosphate occupy a distinct classification reflecting their different nitrogen-to-phosphorus ratios compared with pure DAP — MAP's higher phosphorus-to-nitrogen ratio (approximately 11-52-0) makes it preferred in high-phosphorus application programs and in blending operations. The inclusion of DAP-MAP mixtures in this heading means that blenders must carefully characterize the dominant compound to determine the correct classification. Like DAP, MAP is a globally traded commodity where origin and trade-remedy status are key cost variables for US importers.

Under SITC 56294, mixtures of monoammonium phosphate and diammonium phosphate are explicitly included in the MAP heading rather than the DAP heading. At the HTS level used for US customs entry, the specific composition ratio and the applicable tariff schedule notes govern classification, so a certificate of analysis and consultation with a licensed customs broker are advisable for mixed-product shipments.
MAP is preferred when soil pH management is a concern, as it has a more acidifying effect than DAP, and when a higher phosphorus-to-nitrogen ratio is agronomically required. DAP is more common in broad-acre grain programs. Blenders often combine both to hit a target N-P ratio, which is why the mixture category exists as a distinct trade classification.
