Platts to launch two Ammonium Sulfate CFR Brazil assessments; change methodology of existing AS CFR Brazil range assessment

Platts, part of S&P Global Commodity Insights, will launch two weekly price assessments for ammonium sulfate delivered to Brazil, CFR Brazil North-Northeast and CFR Brazil South-Southeast, effective Sept. 4, 2025.

The assessment will capture market activity in Brazil's different regions and complement Platts' existing coverage of the AS market in the country.

The assessments will have the following specifications:

Assessment name: Ammonium Sulfate CFR Brazil SSE

  • Quality: 21% N, compacted/granular ammonium sulfate
  • Quantity: 5,000-10,000 mt
  • Basis and location: CFR Paranaguá, Paraná
  • Timing: Delivered between seven and 40 days from the date of publication
  • Frequency: Weekly (Thursdays)
  • Appears in: Nitrogen Market Report
  • Unit of assessment: $/mt
  • Timestamp: 16:30 São Paulo, following the São Paulo publishing calendar

Assessment name: Ammonium Sulfate CFR Brazil NNE

  • Quality: 21% N, compacted/granular ammonium sulfate
  • Quantity: 5,000-10,000 mt
  • Basis and location: CFR Aratu, Bahia
  • Timing: Delivered between seven and 40 days from the date of publication
  • Frequency: Weekly (Thursdays)
  • Appears in: Nitrogen Market Report
  • Unit of assessment: $/mt
  • Timestamp: 16:30 São Paulo, following the São Paulo publishing calendar

The weekly price assessments will be published as a single "close" value to a 16:30 São Paulo timestamp and follow the São Paulo publishing calendar.

Alignment of weekly range assessment methodology

Additionally, the weekly range for Ammonium Sulfate (21% N) Caprolactam Compacted/Granular CFR Brazil $/mt Wkly (FASCG04) will reflect the lowest and highest values published from the above-mentioned AS CFR Brazil SSE and NNE assessments, effective Sept. 4, 2025. No fresh market information will be taken into account.

For example, if CFR Brazil SSE is assessed at $300/mt for a week and CFR Brazil NNE is assessed at $350/mt, Ammonium Sulfate (21% N) CFR Brazil $/mt Wkly (FASCG04) will be assessed at $300-$350/mt.

Platts will also amend the specifications of weekly CFR Brazil assessment (FASCG04) to align to those of the above mentioned AS CFR Brazil SSE and NNE assessments.

The updated specifications for the Ammonium Sulfate (21% N) Caprolactam Compacted/Granular CFR Brazil $/mt Wkly (FASCG04) are as follows:
