As the US investigated the global semiconductor industry and the US Department of Commerce planned to impose additional tariffs on imported chips, TSMC (TSM.US) warned that it will significantly reduce the demand for electronic products from TSMC's customers if the US imposes tariffs on imported chips, potentially leading to a sharp decline in revenue and affecting the progress of TSMC's US$165 billion investment plan in Arizona, according to Tom's Hardware. TSMC said in its letter to the US Bureau of Industry and Security (BIS) that the reduced market demand from its top US customers might decrease the demand for TSMC's manufacturing capacity and onshore services, according to the report.

Tariffs would increase the prices of end-consumer products and reduce the demand for such products and their semiconductor components, the letter added. TSMC urged the US government to avoid imposing additional tariffs or other restrictive measures on semiconductors manufactured outside the US. It is reported that Dell Technologies (Dell.US) and Hewlett Packard Enterprise Company (HPE.US) agreed with the content of TSMC's letter.
