Platts launches daily FOB NOLA Ammonia barge assessment and updates weekly assessment Sept. 24

Platts, part of S&P Global Energy, has launched a new daily assessment for ammonia barges in New Orleans and refined the specifications of its existing FOB NOLA ammonia barge weekly assessment, effective Sept. 24, 2026.

This launch follows market feedback on ammonia trade flows in the US domestic market.

The new daily assessment has the following specifications:

Assessment Name: Ammonia FOB NOLA Barge daily (FAMNJ00)

Quality: Anhydrous ammonia, which is around 82% nitrogen and is stored and transported as a liquid under pressure at around minus 33 degrees Celsius

Quantity: 5,000 short tons

Basis and location: FOB barge New Orleans, Louisiana

Timing: Spot. Product to be shipped up to 30 days forward

Frequency: Daily

Unit of assessment: $/st

Timestamp: 16:30 São Paulo close, published according to the São Paulo publishing calendar

In addition to the launch above, the existing weekly assessment has been revised to align with the daily assessment's specifications.

The FOB NOLA Brg $/st Wkly (FAMNJ04) assessment was previously assessed on a weekly basis as a low and high range, covering both spot and contract, with a minimum quantity of 1,500 st. Effective Sept. 24, the weekly reflects the lowest and highest of the new FOB NOLA Barge daily assessment published over the preceding trading week (Friday to Thursday).

Platts has also launched a "close" value for the weekly assessment, reflecting market value at 16:30 São Paulo time on Thursdays, mirroring that day's daily assessment.

The changes to the FOB NOLA Brg $/st Wkly assessment are outlined below:
