Investing.com - Some of the nations best-known tech companies will be hit if the U.S. and China impose another round of tit-for-tat tariffs.Analysts say semiconductor firms like Intel (NASDAQ:INTC) and Qualcomm (NASDAQ:QCOM) are vulnerable because they often send their computer chips to China for assembly, testing and packaging. That makes them subject to U.S. tariffs on chips when they re-enter the country.Amazon (NASDAQ:AMZN), Google (NASDAQ:GOOGL) and Facebook (NASDAQ:FB) could be affected if the Trump administration follows through with tariffs on networking equipment, which is used in the companies' cloud computing operations. Modems and routers are also on the list of products in the Trump administration's second round of tariffs. Analysts say that would impact companies like Microsoft (NASDAQ:MSFT).
