The Wind Tower Trade Coalition is an association of domestic manufacturers of utility scale wind towers. The coalition filed a suit in the U.S. Court of International Trade against the U.S. Department of Commerce. It challenged the Commerce Department's decision to impose only prospective antidumping duties, rather than retrospective (retroactive) duties, on imports of utility-scale wind towers from China and Vietnam. The department had found that the domestic industry had not suffered any "material injury" or "threat of material injury" from such imports. It had further found that the industry would be protected by a prospective assessment. Can an antidumping duty be assessed retrospectively? If so, should it be assessed here? Discuss.
