“The new rule makes it clear that any use of American software or American fabrication equipment is banned and requires a license.”
Secretary of State Mike Pompeo said in a tweet that the US government “dealt a direct blow to Huawei and the repressive Chinese Communist Party by further limiting Huawei’s ability to acquire US technology and compromise the integrity of the world’s networks and Americans’ private information.”
Huawei did not immediately comment.
With US-China relations at their worst in decades, Washington is pushing governments around to world to squeeze out Huawei, arguing it would hand over data to the Chinese government for spying. Huawei denies it spies for China.
In an appearance on Fox on Monday, President Donald Trump accused Huawei, without evidence, of spying on Americans. “We don’t want their equipment in the United States because they spy on us,” Trump said.
The new actions, effective immediately, should prevent Huawei’s attempts to circumvent US export controls, Commerce said.
It “makes clear that we’re covering off-the-shelf designs that Huawei may be seeking to purchase from a third-party design house,” one Commerce Department official told Reuters.
Commerce Department officials declined to say if they had or would approve any licenses for chipmakers to supply Huawei or if any applications were pending.
The Semiconductor Industry Association, however, said that “these broad restrictions on commercial chip sales will bring significant disruption to the US semiconductor industry. We are surprised and concerned by the administration’s sudden shift from its prior support of a more narrow approach intended to achieve stated national security goals while limiting harm to US companies.”
A new separate rule requires companies on the economic blacklist to obtain a license when a company on the list, like Huawei, acts “as a purchaser, intermediate consignee, ultimate consignee, or end user.”
The department also confirmed it will not extend a temporary general license that expired Friday for users of Huawei devices and telecommunication providers. Parties must now submit license applications for transactions previously authorised.
The department said it was allowing the temporary general license to expire covering support to existing “personal consumer electronic devices.”
The Commerce Department also adopted a limited permanent authorisation for Huawei entities to allow “ongoing security research critical to maintaining the integrity and reliability of existing” networks and equipment.
Existing US restrictions have had a heavy impact on Huawei and its suppliers. The restrictions announced in May do not fully take effect until September 14.
On August 8, financial magazine Caixin reported Huawei will stop making its flagship Kirin chipsets next month due to US pressure on suppliers.
Huawei’s HiSilicon division has relied on software from US companies such as Cadence Design Systems Inc and Synopsys Inc to design its chips. It outsourced the production to Taiwan Semiconductor Manufacturing Co , which uses equipment from US companies.
TSMC has said it will not ship wafers to Huawei after September 15.
