All of Huawei's smartphones run on ARM architecture.
"The current chipsets already designed may not be affected, but the newer chipsets for late Q4 2019 will not be able to use ARM's license. This will affect even smartphone sales in China," said Tom Kang, Research Director at Counterpoint.
Huawei will not be able to use Google's core suite of software the latter provides.
"Huawei will have to use the open source Android Open Source Project (AOSP) instead. Huawei will lose access to Play Store and key Google apps like YouTube and Gmail," Kang added in a statement.
Qorvo, Skyworks and Broadcom radio frequency (RF) components will also be hard to replace for Huawei's high-end LTE smartphones.
The fourth problem for Huawei is its dependence on chip giant Intel for the cloud, enterprise and infrastructure servers.
Intel has also joined US companies who would not share their technologies with Huawei.
The US has put Huawei on the "Entity List", which prohibits it from buying or selling anything from technology to components from US firms.
Nearly 49 per cent of Huawei's business comes from China, and 51 per cent from overseas markets. Within the overseas markets, Europe accounts for 23 per cent and will probably be the most affected.
The critical price bands would be the ones above $400. These price bands make up for 18 per cent of Huawei's smartphone shipments.
"The timing of the action on Huawei is likely not coincidental - it can be used as a lever to increase the pressure on the Chinese negotiating team as well as damage the company itself.
"We see a struggle for leadership in technology and global power at the core of this action," said Kang.
