U.S. President Donald Trump announced Wednesday the imposition of "massive" tariffs of up to 100 percent on computer chips and semiconductors during a White House address.

Key Announcements:

1. Tariff Structure:

   • "We will impose tariffs of approximately 100% on chips and semiconductors"

   • Exemption for companies building U.S. manufacturing facilities:
     "If (a company) is building (factories) in the United States, no tariffs will be imposed – even if they're still under construction and not yet producing – due to the significant number of jobs and all the associated benefits."

2. Investment Trends:

   • Trump noted: "Many companies are leaving various locations and coming to the United States"

   • Emphasized reciprocal treatment principles

   • Clarified tariffs won't be uniformly applied: "Tariffs won't be imposed at the same level in all cases"

3. Industry Context (per White House):

   • Semiconductors were invented in America

   • Current U.S. production represents only ~10% of global chips

   • The U.S. manufactures none of the world's most advanced chips
