USTR extends deadline for Vietnam intellectual-property investigation
On 10 November 2026, the Federal Register published USTR's notice extending the deadline for findings and any response in its Vietnam intellectual-property Section 301 investigation to 28 February 2027.

- Docket USTR-2026-0364; Federal Register document 2026-22868

Three-month procedural extension
The notice took effect at 12:01 a.m. Eastern Daylight Time on 3 November. USTR opened the investigation on 29 May 2026 under section 302(b)(2) of the Trade Act of 1974 to examine certain Vietnamese acts, policies and practices concerning intellectual-property protection and enforcement.[1]
Complex issues move the statutory deadline
For this type of investigation, section 304(a)(3)(A) generally requires findings on actionability and any response within six months of initiation. The notice records USTR's determination that the investigation involves complex or complicated issues requiring additional time and invokes the nine-month period in section 304(a)(3)(B). The revised deadline is no later than 28 February 2027.[1]
No tariff or finding yet
This is a procedural extension, not a determination that Vietnam's conduct is actionable. The notice does not impose duties, restrict imports or create a new customs filing. USTR must still decide whether the investigated practices meet the statutory test and what action, if any, to take. The additional time does not predetermine that outcome.[1]
Monitor the eventual determination
Businesses with Vietnam-linked intellectual property, sourcing or sales exposure should track the docket and distinguish this investigation from existing US tariff and trade measures. Importers should not change customs treatment solely because of the extension. If USTR later issues a finding or response, groups should verify the products, conduct, effective date and transition provisions in that instrument before adjusting entries, contracts or landed-cost forecasts.[1]
