The US Department of Commerce (DOC) announced new preliminary antidumping duties against rebar imports from Mexico after an administrative review.
During the review period of Nov. 1, 2017 to Oct. 31, 2018, Mexican rebar producers Deacero and Grupo Simec were found to have made sales of rebar at less than normal value. As such, the DOC has issued higher preliminary dumping margins for both companies, along with all other rebar producers/exporters in Mexico:
| Producer/Exporter | Previous AD rate | New AD rate |
| Deacero | 0% | 7.25% |
| Grupo Simec | 3.65% | 6.75% |
| All others | 3.65% | 7.11% |
