The easiest way to estimate the real semiconductor trade is to watch the revenue of TSMC. In 2016, TSMC reported revenue of $30B, representing roughly half of all semi.
The amount of US imports is quite funny also because USA places all values on the last country. As a result, China is responsible for the entire value of an iPhone though it only performed some low value assembly efforts.
The end results are that many tech companies have a lot of cash sitting in Panama, Bermuda, Cayman Island etc to avoid paying USA taxes. This is why Trump changed the tax laws to get these money back.
