The DoC has imposed the following duties: Thailand 2.09 per cent, China 5.76 per cent, Malaysia 62.74 per cent, India 5.91 per cent and Viet Nam 6.07 per cent.
Indonesia and Ecuador also have subsidies of 0.81 per cent and 0.39 per cent respectively, but the amounts are too low for duty to be collected.
Malaysia will be hardest hit if its duty is not relaxed, meaning it will no longer be a major supplier of shrimps to the US.
In 2012, Malaysia exported about 50 million pounds of shrimp to the US.
The final decision will be made in mid-August.
