Anti-dumping duty rescission on Vitamin C imports after mid-term review found insufficient evidence of dumping. The Central Government rescinded the definitive anti dumping duty on Vitamin C imports from the United States and Canada after a mid term review found inadequate evidence to maintain findings of dumping, material injury and causal link; the rescission is effected under the Customs Tariff statutory provisions and anti dumping rules, and is subject to a savings clause for actions taken prior to rescission.
