Platts to expand its US Gulf Coast petcoke market reporting

Platts, part of S&P Global Commodity Insights, will expand its US Gulf Coast petroleum coke (petcoke) market reporting by adding a mid-high sulfur assessment and making specification amendments to its existing petcoke price assessment series, effective May 16, 2025.

Platts first proposed the new price assessment and specification amendments to its existing assessment series in a subscriber note published on March 19, 2025, following research and market engagement.

Market participants indicated the need for more transparency around price differentials between grades of petcoke defined primarily by their sulfur content. The note is available here(opens in a new tab).

The new price assessment will reflect the value of FOB USGC petcoke cargoes with a 5.5% typical sulfur specification and a sulfur range of 5.1%-5.9% in US dollars per metric ton. The assessment will reflect cargoes of a typical volume of 10,000 mt or more. Cargoes of other grades, qualities and locations may be normalized for assessment purposes.

Concurrently, Platts will amend the specification range for its existing FOB US Gulf Coast High Sulfur assessment (CPAAA00) from 5.5%-7% to 6%-7%. Other specifications for FOB US Gulf Coast petcoke assessments will remain unchanged.

Platts FOB USGC petcoke assessments appear in Platts Coal Trader, Platts Coal Trader International and on Platts Service Page Numbers GCN0960 and GCI0960.
