Platts proposes to launch FOB US Gulf Sulfur price assessment

Platts, part of S&P Global Energy, is proposing to launch a weekly FOB US Gulf Sulfur price assessment, effective April 2, 2026.

The proposed assessment would capture spot market activity in the US Gulf and complement Platts' existing coverage of the US sulfur market.

The proposed assessment would have the following specifications:

• Assessment Name: Solid Sulfur FOB US Gulf
• Quality: Elemental sulfur (solid/granular) in bulk
• Quantity: 35,000-40,000 metric tons
• Basis and location: FOB US Gulf
• Timing: Loading four to seven weeks forward from the date of publication
• Frequency: Weekly
• Unit of assessment: $/mt

The weekly price assessment would be published on Thursday as a single "close" value with a 1630 São Paulo timestamp and follow the São Paulo publishing calendar. If Thursday is a non-publishing day, then the assessment will be published on the previous working day.

The assessment would appear in the Sulphur Market Report and on the fixed page FE0361, effective May 7.
