  • Tariff increases target strategic sectors, including electric vehicles, batteries, semiconductors, solar cells and medical products.
  • Changes from the May 2024 proposal include: 
    • Increased tariffs on facemasks, medical gloves and syringes/needles
    • Exclusion for enteral syringes through January 1, 2026
    • Exclusion process for ship-to-shore cranes ordered before May 14
  • An exclusion process for certain machinery used in domestic manufacturing will be launched soon.
  • Fourteen temporary exclusions for solar manufacturing equipment were approved, effective retroactively to January 1 through May 31, 2025.
