CDSOA, otherwise known as the Byrd Amendment, was passed on October 28, 2000 and was repealed effective October 1, 2007. The provisions of this act allow for anti-dumping and countervailing (AD/CV) duties collected by CBP to be disbursed to domestic producers injured by foreign dumping and subsidies. Per the repeal, AD/CV duties collected on entries made prior to October 1, 2007 are still eligible for CDSOA at liquidation.
