ITCJuly 1, 2026·337-TA-1512·SUPPLEMENTAL COMPLAINT FILED

Certain Foundry Coke; Inv. No. 337-TA-1512 (Violation)

U.S. International Trade Commission

Holding

This supplemental complaint, filed by SunCoke Technology and Development LLC and Jewell Coke Company L.P. in Investigation 337-TA-1512 (Certain Foundry Coke), makes a single correction: it substitutes the name "MTX Group a.s." for "MTX CZ, a.s." wherever the latter appears in the original complaint.

Why It Matters

The filing is a minor housekeeping change that updates the name of an entity identified in the original complaint. It does not alter the patents, accused products, or relief, and the text gives no detail on them. Its effect is to make the complaint's party identification accurate for the investigation.
