The Department of Commerce has determined that KG Dongbu Steel Co., Ltd. is considered the successor to Dongbu Steel Co., Ltd. and Dongbu Incheon Steel Co., Ltd. for the purposes of antidumping duty (AD) cash deposits related to imports from Korea. However, KG Dongbu Steel is not viewed as the successor for countervailing duty (CVD) reasons because of significant ownership changes that might affect subsidy calculations. As a result, for AD purposes, KG Dongbu Steel will inherit the duty rates from Dongbu Steel/Dongbu Incheon, but for CVD, they will not. U.S. Customs and Border Protection will apply these AD rates to future imports from KG Dongbu Steel until further notice.
Simple Explanation
Imagine a toy company is changing its name from "Fun Toys" to "New Fun Toys." For keeping track of old promises, they are considered the same company when it comes to pricing rules. However, for different rules about money and help from other companies, they aren't considered the same because of changes in who owns them and how they work.
