The U.S. will increase tariffs on Chinese semiconductor imports in June 2027, at a rate to be determined at least a month in advance, the Trump administration said in a Federal Register filing on Tuesday.

But in the meantime, the initial tariff rate on semiconductor imports from China will be zero for 18 months, according to the filing from the Office of the U.S. Trade Representative.

As part of an investigation that kicked off a year ago, the agency found that China is engaging in unfair trade practices in the industry.

“For decades, China has targeted the semiconductor industry for dominance and has employed increasingly aggressive and sweeping non-market policies and practices in pursuing dominance of the sector,” the office said in the filing.

The decision to delay new tariffs for at least 18 months signals that the Trump administration is seeking to cool any trade hostilities between the U.S. and China.

Additional tariffs could also become a bargaining chip if future talks break down.

U.S. President Donald Trump and Chinese President Xi Jinping reached a truce in the so-called trade war in October, as part of a deal that included the U.S. slashing some tariffs and China allowing exports of rare earth metals.

The USTR’s Tuesday filing states that tariffs will increase on June 23, 2027.

The notice is the next step in a process focusing on older chips that started during the Biden administration under Section 301 of the Trade Act.

The new 2027 date gives clarity to American firms that have said they are closely watching how U.S. tariffs could affect their businesses or supply chains.

The tariffs are separate from other duties threatened by the Trump administration on Chinese chip imports under Section 232 of the law.
