World Trade Organization panel on Wednesday largely rejected Indonesia’s ​challenge to European Union anti-dumping ‌duties on fatty acid imports from the Southeast Asian country, while finding ​a limited breach related ​to the European Commission’s calculation of ⁠dumping margins.

The panel upheld one ​Indonesian complaint, concluding that the ​European Commission failed to correctly convert the currency of certain transactions. The error ​breached a part of the ​Anti-Dumping Agreement and, as a consequence, also ‌violated ⁠provisions governing the level of anti-dumping duties.

The panel report, circulated to WTO members on Tuesday, stems ​from a ​dispute launched ⁠by Indonesia over anti-dumping measures imposed by the ​EU following an investigation ​by ⁠the European Commission.

Jakarta also challenged what it alleged was an unwritten ⁠methodology ​used by Brussels in ​calculating dumping margins.
