In 2018, imports of reinforcing bars from Mexico were valued at an estimated $51 million. The inquiry was initiated in response to requests from US domestic producers of rebar: Nucor Corporation, Gerdau Ameristeel US Inc., Commercial Metals Company, Cascade Steel Rolling Mills, Inc., Byer Steel Group, Inc., and Steel Dynamics, Inc.

If the DOC preliminarily determines that circumvention is occurring, it will instruct Customs and Border Protection to begin collecting cash deposits on rebar from Mexico that is subject to the inquiry. These duties will be imposed on future imports, and on any unliquidated entries since the date on which Commerce initiated this circumvention inquiry.
