Apple has one of the world’s most complicated supply chains in the world. It starts off with the raw materials coming from all around the world. The raw material has to go to the suppliers where the metals are turned into parts for the iPhone that you will unbox. After the parts are made they are sent to factories in China for a final assembly where the iPhone will be assembled into one piece. After that happens the iPhones are sent all over the world by air so that they arrive at you on time.

As Apple tries to escape tariffs and the trade war, it is moving production out of China—but not to the U.S. Here’s how the tech giant has become so reliant on a global supply chain. Correction: This video incorrectly states that Apple no longer assembles the 2013 Mac Pro in Austin, Texas. The 2013 version is still assembled in Austin, while Apple plans to assemble the 2019 Mac Pro in China.
