Platts to revise moisture levels for iron ore fines netback calculations

Platts, part of S&P Global Commodity Insights, will revise the implied moisture levels used in deriving the FOB netback calculations for various freight routes and vessel classes from their respective CFR China price assessments, effective July 1.

The revisions will apply updated moisture content levels for iron ore fines in the wet-to-dry mt conversions of the freight rates, used in netting back the CFR China iron ore prices to an FOB basis.

The FOB netback calculations result from deducting Platts dry bulk freight rate assessments from Platts daily seaborne assessments for 62% Fe, 58% Fe and 65% Fe iron ore fines on a CFR Qingdao, China basis.

Platts first published a proposal to revise moisture levels for iron ore fines netback calculations on April 1: https://www.spglobal.com/commodity-insights/en/pricing-benchmarks/our-methodology/subscriber-notes/040125-platts-proposes-to-revise-moisture-levels-for-iron-ore-fines-netback-calculations

Following industry feedback and research, Platts is revising the moisture content levels as follows:

In addition, Platts will update the fixed pages PMA1106 and STL1106 of its real-time alerts services to remove shipping routes that do not have a corresponding FOB netback calculation:
