The US government has granted tariff exclusions for smartphones, computers and other electronics imported largely from China, sparing them from President Donald Trump’s steep 125% reciprocal duties. In a notice to shippers, the US Customs and Border Protection agency published a list of tariff codes that will be excluded from the duties.

The exclusions are retroactive to 12:01 a.m.EDT (1601 GMT) on April 5.

The US CBP listed 20 product categories, including the very broad 8471 code for all computers, laptops, disc drives and automatic data processing. It also included semiconductor devices, equipment, memory chips and flat panel displays. The notice did not provide an explanation for the Trump administration’s move, but the late-night exclusion provides welcome relief to major US technology firms, including Apple, Dell Technologies and countless other importers.

The exclusion only applies to Trump’s reciprocal tariffs on Chinese goods, which climbed to 125% this week, according to a White House official. Trump’s prior 20% duties on all Chinese imports that he said were related to the US fentanyl crisis remain in place.

But the official said Trump will launch a new national security trade investigation into semiconductors soon that could lead to other new tariffs on the sector.

Separately, White House spokesperson Karoline Leavitt said in a statement that Trump has made it clear the US cannot rely on China to manufacture critical technologies such as semiconductors, chips, smartphones and laptops.

But she said that at Trump’s direction, major tech firms, including Apple and chipmakers Nvidia and Taiwan Semiconductor “are hustling to onshore their manufacturing in the United States as soon as possible.”
