Donald Trump has initiated a wide-ranging antidumping duty (AD) and countervailing duty (CVD) investigation into countries that export steel to the US.

The investigation is aimed at stopping countries from flooding the U.S. with artificially cheap steel that is undercutting local suppliers. Under the investigation ten countries are subject to AD investigations including Belarus, Italy, Korea, Russia, South Africa, Spain, Turkey, Ukraine, the United Arab Emirates (UAE), and the UK. Only Italy and Turkey are subject to CVD investigations over unfair subsidies.

The alleged dumping margins for Belarus are 161.75 percent to 280.02 percent, Italy 18.89 percent, Korea 33.96 percent to 43.25 percent, Russia 214.06 percent to 756.93 percent, South Africa 128.66 percent to 142.26 percent, Spain 32.70 percent, Turkey 37.67 percent, Ukraine 21.23 percent to 44.03 percent, UAE 84.10 percent, and the UK 147.63 percent.
