Taiwanese shipments to the US rose 87.4 percent to a value of $15.5 billion in May, according to the country's finance ministry. Both figures are new records, reports news agency Bloomberg.
The Trump administration introduced 32-percent tariffs on Taiwan on April 2, on what President Donald Trump called "liberation day." But the legally disputed tariffs were suspended after a few days and have since been put on trial in US courts.
Taiwan's economy is largely based on the export of technical equipment, such as semiconductors and processors.
The export increase in May is impressive, according to Michelle Lam, sinologist at the French major bank Société Générale.
"But I would warn that much of this is pre-emptive export as the US can still impose tariffs on chips and electronics that are today exempt from tariffs," she writes in a comment according to Bloomberg.
