Apple said it was adding Bosch, Cirrus Logic, TDK and Qnity Electronics to its American Manufacturing Program, with plans to invest $400 million through 2030 to expand U.S.-based production of key components.

The move comes as companies increasingly shift manufacturing and critical supply chains to the United States to reduce geopolitical risks and strengthen domestic production.

The expansion builds on Apple's $600 billion, four-year commitment to invest in U.S. manufacturing announced last year.

The new partnerships will focus on producing sensors, integrated circuits and advanced materials used in Apple devices, with some components to be manufactured for the first time in the United States.

Apple said the expansion would help create jobs and bolster U.S. capabilities in semiconductor and advanced electronics manufacturing.

As part of the program, Apple will work with Bosch and Taiwan Semiconductor Manufacturing Co (TSMC) to produce chips for sensing hardware at TSMC's facility in Washington state.

Cirrus Logic will collaborate with GlobalFoundries to develop semiconductor process technologies supporting features such as Face ID.

Longtime supplier TDK will begin making sensors in the United States for the first time, while Qnity Electronics will supply materials critical for semiconductor production and AI-related technologies.
