The dozens of products included on the White House's list of exemptions range from avocados and tomatoes to coconuts and mangoes.
These goods, the Trump administration said on Friday, cannot be produced in sufficient quantities domestically.
Speaking to reporters on Friday, Trump said the decision will affect products that are not produced in the US, "so there's no protection of our industries, or our food products".
He added that he doesn't think more policy rollbacks will be required in the future, saying "I don't think it'll be necessary."
"We just did a little bit of a rollback on some foods, like coffee as an example, where the prices of coffee were a little bit high. Now they'll be on the low side in a very short period of time," Trump said.
