Perhaps the most obvious product line that could be impacted by Huawei's placement on the US trade blacklist is its smartphones. Popular Huawei smartphone models such as the P30 Pro and Mate 20 Pro were built using a variety of components from US tech companies.
The P30 Pro, for example, uses flash storage from Micron, according to iFixit, which was founded in Boise, Idaho, in 1978. It also uses front-end modules from the Massachusetts-based Skyworks Solutions and California-based Qorvo. The company's popular Mate 20 Pro smartphone also includes Skyworks modules and a wireless power receiver from IDT, according to iFixit, which is also headquartered in California.
Supplier Lumentum has also said it's stopped shipping parts to Huawei, according to Reuters. It's unclear precisely how Lumentum's components are used in Huawei's phones, but the components maker said that Huawei was responsible for 18% of its revenue in its last reported quarter. Lumentum is also a supplier for Apple's Face ID facial recognition technology, so it's possible that its parts have been used to power the facial recognition features on phones like the Mate 20.
But those are some of the more granular ways in which Huawei's phones could be impacted by the new requirements. Of course, Google's revocation of Huawei's Android license means Huawei can no longer use the firm's widely popular software. And designs from Arm, which recently told employees to stop working with Huawei, play a big role in Huawei's line of Kirin chips that power its smartphones and tablets. (However, since firms usually license technology from Arm, it's possible that Huawei has years worth of licenses stored for future use.)
New York-based Corning's Gorilla Glass can also be found on a wide variety of Huawei smartphones ranging from its Mate 20 Pro to its less expensive Honor V8, among many other models, according to the glass maker.
