Huawei has been hobbling along for a few years now with limited access to US chips and technology, with both the Trump and Biden administrations banning general exports to the company. Huawei hasn't seen zero US chips, but every sale has had to be approved by the government, with the restrictions being tweaked several times since the initial ban in 2019. Reuters, The Financial Times, and several other outlets have reported that the Biden administration is putting even tighter restrictions on Huawei, with FT saying the US is working toward a "total ban" on sales to the Chinese tech company.

Like every tech company, Huawei buys components from a bunch of different suppliers to make its network equipment and smartphones. While a ton of manufacturing is done in China, there aren't many options for CPUs, and US companies Qualcomm and Intel have been keeping Huawei afloat with limited government-granted export licenses. Intel chips have meant the company can still build servers, and while 5G tech was banned from export, Qualcomm went out of its way to make special, 4G-only versions of its latest SoCs.
