Platts to update US Domestic Urea Ammonium Nitrate price assessment, Sept. 3
Platts, part of S&P Global Energy, will amend the methodology and specifications of its weekly US Domestic Urea Ammonium Nitrate (UAN) price assessment, effective Sept. 3, 2026.
Following market feedback and a review of trading activity, Platts will introduce a daily close value and update the assessment specifications to better reflect prevailing spot market liquidity and trading practices in the US Gulf Coast UAN market.
The low and high elements of the assessment will be standardized at $1/short ton above and below the assessed close value. As well as introducing a close value, Platts will adjust the basis volume, timing, and location to better reflect market activity.
The amendments are detailed below:
