WASHINGTON, Aug 6 (Reuters) - President Donald Trump said the United States will impose a tariff of about 100% on imports of semiconductors but offered up a big exemption - it will not apply to companies that are manufacturing in the U.S. or have committed to do so.

President Donald Trump says he's imposing a 100% tariff on computer chips— a move that raises the specter of higher prices for electronics, autos, household appliances and other essential goods that depend on the processors.

President Donald Trump said he will impose a 100% tariff on imports of semiconductors and chips, but not for companies that are "building in the United States."
