Perhaps the most obvious product line that could be affected 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 the 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.
The supplier Lumentum also said it has 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 such as the Mate 20.
But those are some of the more granular ways in which Huawei's phones could be affected by the new requirements. Of course, Google's revocation of Huawei's Android license means Huawei can no longer use the company'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, because firms usually license technology from Arm, it's possible that Huawei has years' worth of licenses stored for future use.)
The New York-based Corning's Gorilla Glass can also be found on a wide variety of Huawei smartphones, including its Mate 20 Pro and its less expensive Honor V8, according to the glass maker.
Huawei works with many US-based companies on its laptop line as well.
Laptops such as the MateBook X and MateBook 13 run on Microsoft's Windows operating system. Like many other US companies that work with Huawei, Microsoft has not made any public statements about its relationship with Huawei since the company was blacklisted. But it did recently remove Huawei's laptops from its online store.
Intel, a key supplier of chips for Huawei's laptops, has also told employees that it would not supply Huawei until further notice, according to Bloomberg. Intel's chips power a variety of Huawei laptops, including the MateBook 13, MateBook X Pro, MateBook X, and MateBook E.
Certain models, such as the MateBook 13 and the MateBook X Pro, also include an option for graphics powered by Nvidia, which is headquartered in Santa Clara, California.
Corning's Gorilla Glass can also be found on laptop models such as the MateBook X Pro, MateBook 13, MateBook 14, and MateBook X, according to the company.
Huawei also sells a variety of tablets in different sizes and price points. There's the MediaPad M5 line, which comes in 8.4-inch and 10.8-inch sizes, in addition to a cheaper "lite" model, as well as its T-series of MediaPad tablets.
But these slates run on Android, which means Huawei may have to use an alternative operating system for future MediaPad products. They also all run on Huawei's Kirin chipsets, which are based on Arm's underlying technology. While the company could continue manufacturing existing Arm-based chips, the ban may prevent it from using the company's designs in new chips moving forward, according to the BBC.
Like many consumer tech giants, Huawei also has a stake in the wearables market — the company sells a variety of smartwatches, fitness trackers, and sports watches.
Some of these products use components from US-based companies as well. The company's TalkBand B3 fitness tracker uses Corning Gorilla Glass, according to Corning's website, as does the Huawei Fit, according to the Chinese company's US product page.
