Trading partners might not make good on their commitments, tariffs could drive up inflation and stymie growth, and courts could rule against the president’s ad hoc levies.

Many smaller countries’ exports have faced 10 percent tariffs since the president first announced, then suspended, an initial wave of policies in April. Others have staved off eye-watering rates after brokering deals with the United States that set their tariffs generally between 15 and 20 percent.

That’s not to say tariffs won’t hurt; CEO Tim Cook said tariffs will likely cost the company $1.1 billion this quarter. But analysts say Apple has bigger concerns, such as its future product strategy and approach to artificial intelligence, a burgeoning field that the tech behemoth is perceived to be behind in.
