US Customs will subject at least one more Vietnamese export sector, likely solar cells, steel or furniture, for enhanced transshipment enforcement within 90 days, despite Hanoi's new crackdown pledges.

Vietnam was named among more than 40 trading partners at elevated risk of tariff evasion in a recent US report, and Washington is moving toward AI-driven customs screening plus rules that could tie origin status to Chinese ownership of Vietnamese factories. Enforcement promises rarely satisfy US officials fast enough to head off action, meaning compliance costs rise for exporters well before Hanoi's fraud crackdown produces measurable results.
