Taiwan is moving quickly to preserve recently negotiated trade benefits with the United States after the U.S. Supreme Court struck down President Donald Trump’s emergency tariff authority, injecting fresh uncertainty into U.S.–Taiwan trade relations.

Vice Premier Cheng Li-chiun said the government is in close contact with U.S. officials to ensure the hard-won preferential terms remain intact. Her remarks followed Trump’s warning that countries should not retreat from newly negotiated agreements, adding that he could impose significantly higher duties under alternative trade laws, the Taipei Times reported Tuesday.

Taiwan has secured two agreements reducing tariffs on its exports to 15% from 20%. Under a deal reached last month, Taiwanese companies committed to invest $250 billion in the U.S. to expand semiconductor, energy, and artificial intelligence production, and to guarantee an additional $250 billion in credit to support further investment. A second agreement finalized this month reaffirmed the 15% rate and outlined a timetable to eliminate or reduce tariffs on nearly all U.S. goods, alongside increased purchases of American products, including natural gas.

Trump Reignites Semiconductor Dispute

Semiconductor tensions escalated after the court ruled 6-3 that Trump’s import tariffs violated the 1977 International Emergency Economic Powers Act. Trump responded by criticizing Taiwan’s chip sector, stating, “Taiwan came [into the chip sector and] they stole our chip business,” and argued that it displaced American leaders such as Intel Corp. (NASDAQ:INTC).

His remarks targeted Taiwan’s dominant semiconductor industry, led by Taiwan Semiconductor Manufacturing Company Ltd. (NYSE:TSM), the world’s largest contract chipmaker and a key supplier of advanced AI chips to major U.S. technology firms.

Export Surge Raises Future Risks

Cheng, who led the negotiations, said Taiwan is not reopening talks but will remain engaged to protect existing terms, even if Washington adopts new tariff measures through alternative legal channels. She added that countries with signed agreements should be in a stronger position if new trade tools are used and said semiconductor tariff treatment will remain unchanged.

However, she acknowledged Taiwan’s large U.S. trade surplus could pose risks. Recent U.S. data show Taiwan’s exports to the U.S. surpassed China’s in December, with semiconductor shipments reaching nearly $24.7 billion, exceeding mainland China’s $21.1 billion.

Amid escalating tensions, the White House said Trump will travel to China from March 31 to April 2 for talks with Xi Jinping, adding another geopolitical dimension to the evolving chip and trade dispute.

TSM Price Action: Taiwan Semiconductor shares were up 1.64% at $376.11 during premarket trading on Tuesday. The stock is trading near its 52-week high of $380.00, according to Benzinga Pro data.
