The period of MAP and DAP prices trading near parity will be short-lived because newly-imposed US import tariffs could amplify MAP supply woes, market participants told Argus.
MAP and DAP prices have traded in close proximity since early January, diverting from the significant MAP premium seen last spring and summer when a surplus of DAP was imported into the US.
After limited MAP barge trading in March, activity accelerated at Nola this week as it became clearer that all non-North American phosphate imports would face at least 10pc import tariffs imposed by President Donald Trump starting last week.
The Nola MAP price was assessed at a midpoint of $636.50/st fob this week, up by $9/st from last week, while DAP was assessed $12.50/st higher at $632.50/st fob Nola.
Despite the "reciprocal" tariffs on certain phosphate producing countries being lowered to a universal 10pc this week by Trump for 90 days — in line with the original tariff imposed on other countries such as Saudi Arabia and Australia last week — the remaining levy is still enough to deter vessels from coming to Nola, sources said.
In response, the Nola MAP price has averaged a $5.75/st premium to the Nola DAP price for April so far, flipping from a $3.88/st average discount in March.
That is still a far cry from October 2024, when the Nola MAP price averaged a $61.45/st premium over the Nola DAP. From August through November, the Nola MAP price was 13pc higher on average than DAP.
US market participants expect the premium to expand in the coming months as MAP is the preferred product of most farmers during the fall application season, potentially impacting buying decisions for that period.
The US from July through February has imported 759,000 metric tonnes (t) of DAP, down by 26pc from the same period last year, according to US Census Bureau data. This lapse in imports for the start of 2025 was an initial driver in DAP's rising premium over MAP. In comparison, MAP imports for the same period have totaled roughly 853,000t, up by just 5pc from the year before.
But at least 290,000 t of MAP will need to be brought into the US between now and the start of the summer to equal out with the tonnage imported for the full 2023-24 fertilizer year ahead of fall applications. That is a task that may not be easily achieved given the new tariff on most phosphate imports.
One buyer this week said they could consider switching usual MAP demand toward an alternative NPS product heading into October and November given the difficult supply outlook for the US.
"We are very much in wait and see mode, trying to see how tariffs evolve and how it works its way into the market in terms of price," another buyer said.
The significant premium MAP held last fall also limited overall phosphate applications conducted by farmers, therefore raising the bar for the amount of phosphate fertilizer farmers will need to put into the ground later this year to replenish soil nutrients.
