The U.S. Department of Commerce imposed antidumping duties on Chinese exporters after its preliminary investigation found they sold cast iron soil pipe fittings in the U.S. at 68.37% to 109.95% less than fair value.
The agency said it will instruct U.S. Customs and Border Protection to collect cash deposits from importers of cast iron soil pipe fittings based on the determined preliminary dumping rates.
The companies found to have "dumped" their products in the U.S. include Sibo International Ltd., with a preliminary dumping rate of 109.95%; Shanxi Xuanshi Industrial Group Co. Ltd., at 68.37%; and Wor-Biz Trading Co. Ltd. (Anhui), at 78.86%.
All other exporters were found to be eligible for a separate rate, while China-wide entity was assigned a dumping margin of 109.95%.
Commerce said imports of cast iron soil pipe fittings from China were valued at an estimated $8.6 million in 2016.
The department is set to announce its final determination by June 28.
"Today's decision allows U.S. producers of cast iron soil pipe fittings to receive relief from the market-distorting effects of potential dumping while we continue our investigation," Commerce Secretary Wilbur Ross said.
