Platts to launch two regional MAP, DAP FOB US Gulf Coast assessments effective Aug. 7

Platts, part of S&P Global Commodity Insights, will launch two weekly price assessments, FOB Tampa granular diammonium phosphate and FOB Tampa monoammonium phosphate, effective Aug. 7, 2025.

These assessments will capture market activity in the US Gulf and complement Platts' existing coverage of the DAP and MAP markets in the country.

Platts originally proposed to launch these assessments in a subscriber note published June 23, available here(opens in a new tab).

These assessments will 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 eight to 60 days forward
  • Frequency: Weekly (Thursdays)

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

The weekly price assessments will be published as a single "close" value with a 16:30 São Paulo timestamp and follow the São Paulo publishing calendar. The assessments will appear in the Phosphates Market Report and the US Fertilizer Report.

Alignment of weekly range assessment methodology

Additionally, Platts will align the specifications and formalize the relationship between the new 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 will 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 will be considered in this assessment.

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