In April, the month that President Trump first announced reciprocal tariffs on China that peaked at 145%, Chinese smartphone exports to the US, including Apple’s, dropped 72% to under $700 million, down from $2.5 billion a month earlier, Bloomberg reports. That’s the lowest it’s been since 2011. Smartphones saw the biggest month-on-month change in export value of any product China exports. It remains to be seen how much a temporary tariff truce between the two nations revives trade.

In Apple’s second quarter, which covers the three months ending March 29, sales of iPhones and other hardware were the key source of better-than-expected revenues, causing some to fret that this strength was a one-off driven by front-running of potential tariffs.
