The Cast Iron Soil Pipe Institute (CISPI) applied the anti-dumping (AD) and countervailing duty (CVD) investigation against Chinese cast iron soil pipe (CISP) to the United States Department of Commerce (DOC) and the United States International Trade Commission (ITC) on behalf of United States domestic industries on January 26th.

The USITC immediately launched a survey of damage to the local industry, and the USDOC would decide whether to file this case within 20 days.
