"This ruling potentially questions the validity of a number of other CVD (countervailing duty) proceedings conducted by the United States on products of Indian origin.
"The government is undertaking an evaluation all other products of Indian origin on which the US has applied the same provision to arrive at CVD," the Commerce Ministry said.
This provision, it added, has been in existence in the US for many years and India is the first country to successfully challenge this provision.
The measures continue to be in force and adversely impact the Indian exports, the Ministry added.
The World Trade Organisation Dispute Settlement Panel has held that the US law mandating cumulation of non-subsidised imports with subsidised imports while determining injury in a CVD investigation is inconsistent with WTO obligations.
The panel also held that the US had no factual basis to hold that the grant of mining rights for iron ore and coal was a subsidy.
It has also found that the US should not have ignored market prices available in India while determining the amount of subsidies, if any.
The WTO body could not consider some of India's claims such as those relating to the methods of calculating the amount of subsidies and one relating to the application of adverse fact available.
The Panel has also not accepted India's claim that NMDC was not a "public body" within the meaning of WTO law, disregarding the previous ruling of the WTO Appellate Body in another WTO case.
"The ruling is appealable before the WTO Appellate Body and the decision to appeal against the same is currently under active consideration, in light of the systemic concerns on some of India's claims denied by the Panel" the Commerce Ministry added.
