The WTO Panel Report on Australia's Anti-Dumping Measures on A4 Copy Paper explores when higher duties can be imposed due to market situations in the exporting country. It also discusses how these duties are calculated using benchmark costs. This report allows countries to respond to government-induced distortions, deviating from previous decisions that focused on private actions. However, it leaves some questions unanswered about how these calculations are adopted, giving investigating authorities room to increase dumping margins.
