Platts proposes to update Americas MAP, TSP price assessments Aug 7
Platts, part of S&P Global Commodity Insights, proposes to update the specifications of six Americas Monoammonium Phosphate price assessments and one Triple Superphosphate price assessment, effective Aug. 7, 2025.
The amendments would refine and evolve specifications such as quality, quantity and timing for the assessments to better reflect the Phosphate market activity dynamics in the Americas region of each assessment location.
The basis and location specification of each of these assessments would be refined to bring more transparency to the characteristics of each of these price assessments.
The weekly Phosphate price assessments would be published as a single "close" value, along with the low and high values published at a standardized $1/mt either side of the assessed close value.
The affected assessments are as follows:
- MAP FOB NOLA US Domestic $/st Wkly (FMAPD04)
- MAP FOB Twin Cities MN $/st Wkly (FMAPF04)
- MAP FOB Cincinnati OH $/st Wkly (FMPCB04)
- MAP FOB Quad Cities/East Dubuque $/st Wkly (FMAPI04)
- MAP FOB St. Louis MO $/st Wkly (FMAPJ04)
- MAP FOB Tulsa OK $/st Wkly (FMPTB04)
- TSP FOB Mexico $/mt Wkly (FGTSE04)
The proposed specifications for all the weekly assessments are detailed below:
