Vietnam Section 301 IP Investigation: Comment Deadline and Tariff Watch
USTR's May 2026 Section 301 investigation into Vietnam intellectual-property protection and enforcement, including comment timing and importer watch items.
Quick Answer
USTR initiated a new Section 301 investigation into Vietnam's intellectual-property protection and enforcement practices. This is an investigation, not a current tariff. Written comments are due July 2, 2026. Vietnam importers should track the docket separately from IEEPA refunds, Section 122 litigation, and the broader forced-labor Section 301 proposed action.
