U.S. President Donald Trump has signed a new executive order granting tariff exemptions to certain trading partners on products including nickel, gold, pharmaceutical ingredients, and chemicals. The move, effective Monday, targets items that cannot be produced sufficiently in the U.S. and aims to strengthen reciprocal trade agreements. Countries entering such agreements will enjoy zero tariffs on over 45 products, while some existing exemptions, like plastics and polysilicon for solar production, are revoked. The measure seeks to protect U.S. economic and national interests.
