Platts proposes to launch two regional MAP, DAP FOB Bulk US Gulf assessments

Platts, part of S&P Global Commodity Insights, proposes to launch two weekly price assessments, FOB Tampa Granular diammonium phosphate (DAP) and FOB Tampa monoammonium phosphate (MAP), effective Aug. 7, 2025.

The proposed assessments would capture market activity in the US Gulf and complement Platts' existing coverage of the DAP/MAP market in the country.

The proposed assessments would have the following specifications:

Assessment Name : Diammonium Phosphate FOB Tampa FL $/mt Wkly

Quality : Bulk granular diammonium phosphate with 18% nitrogen, and 46% phosphorus content, DAP (18-46-0)

Quantity : 20,000-30,000 mt

Basis and location : FOB Tampa, Florida

Timing : Loading 8-60 days forward

Frequency : Weekly (Thursdays)

Unit of assessment : $/mt

Timestamp : 16:30 Sao Paulo, following the Sao Paulo publishing calendar

Assessment Name : Monoammonium Phosphate FOB Tampa FL $/mt Wkly

Quality : Bulk granular monoammonium phosphate with 11% or 12% nitrogen, and 52% phosphorus content, MAP (12-52-0/11-52-0)

Quantity : 20,000-30,000 mt

Basis and location : FOB Tampa, Florida

Timing : Loading 8-60 days forward

Frequency : Weekly (Thursdays)

Unit of assessment : $/mt

Timestamp : 16:30 São Paulo, following the São Paulo publishing calendar

The weekly price assessments would be published as a single "close" value with a 16:30 Sao Paulo timestamp and follow the Sao Paulo publishing calendar. The assessments would appear in the Phosphates Market Report, US Fertilizer Report, and on Platts Connect.

Alignment of weekly range assessment methodology

Additionally, Platts proposes to align the specifications and formalize the relationship between two proposed assessments and the established weekly Diammonium Phosphate/Monoammonium Phosphate FOB US Gulf, Bulk price assessment (FDPBA04), effective Aug. 7, 2025.

The low and high of the weekly DAP/MAP range assessment would now be derived from the above proposed MAP FOB Tampa and DAP FOB Tampa assessments. For example, if FOB Tampa DAP is assessed at $650/mt and FOB Tampa MAP at $680/mt, the FOB US Gulf, Bulk DAP/MAP weekly range will be reported as $650-$680/mt. No fresh market information would be taken into account.

The specifications for the existing weekly assessment will also be adjusted to align with the above proposed assessments. The revised specifications for the DAP/MAP FOB Bulk US Gulf price assessment would read as follows:

The assessment would continue to appear in the Phosphates Market Report, US Fertilizer Report, and on Platts Connect.
