China exports lots of stuff to the USA and those containers go back empty. They can easily be filled up with stolen iPhones and catalytic converters for recycling, so that they aren’t all empty.
That’s way too much trouble, and Chinese customs is really serious about their 100% tariff for DIY car imports. Stolen iPhones and cats are much easier to smuggle in, and have little value outside of Chinese recyclers.
Power tools probably not though.
