In a notice published late Friday night, US Customs and Border Protection issued new guidance on his so-called reciprocal tariffs, which were announced just a week and a half ago and then saw a 90-day pause on most countries save for the baseline 10% rate but additional hikes on China to a prohibitive 125%. After including his earlier levies, that sent the total rate on China to 145%.

The exemptions includes smartphones, computers, semiconductors, solar cells, flat panel TV displays, flash drives, memory cards and solid-state drives for data storage.

That comes after China hiked its own duties on US imports to 125% on Friday but said it would stop retaliating, while Trump signaled he was optimistic about a deal with Beijing, giving investors some hope that their trade war could de-escalate.

The products listed under the exemptions Friday night could still be hit with duties later but they are likely to be lower than what Trump initially unveiled.

For example, he has said that tariffs on semiconductors are on the way, following similar moves on imports of steel, aluminum and autos.

Still, the exemptions also offer huge relief for US companies like Apple that assemble and import devices in China. The iPhone maker’s shares have been crushed since Trump ramped up tariffs on China.

Meanwhile, Wall Street analysts have pointed out that the cost of making many devices in the US would add thousands of dollars to their price tags and take years to set up production.

In recent days, consumers have been rushing to buy electronics before tariffs kick in, and businesses that rely on overseas production have been canceling orders from suppliers.
