Who it hits
Importers of certain chassis and subassemblies sourced from Mexico, Thailand, or Vietnam. AD duties will be assessed on covered merchandise at the rates set in Commerce’s final determinations.
What importers should do
Review the full notice for the specific scope, covered HTS subheadings, and producer/exporter-specific dumping margins. Confirm whether your products and suppliers fall within scope, and plan for AD cash-deposit requirements and potential retroactive liability on covered entries.
