Huawei Hoarded 5G Chips Before Trump Sanctions, Says Bloomberg

Huawei Technologies Co. quietly spent months racing to stockpile critical radio chips ahead of Trump administration sanctions, ensuring it can keep supplying Chinese carriers in their $170 billion rollout of 5G technology through at least 2021, according to a Bloomberg report.

Partner Taiwan Semiconductor Manufacturing Co. began ramping up output in late 2019 of Huawei’s 7-nanometer Tiangang communications chips, the most crucial element in 5G base stations, people familiar with the matter said.

The Taiwanese contract manufacturer eventually shipped more than two million units at Huawei’s behest ahead of the sanctions cutoff last month, one of the people said, asking not be identified discussing internal matters. The sheer magnitude of orders at one point got TSMC executives wondering whether they had underestimated global demand, the person said.

Huawei’s breakthrough in securing essential supplies underscores the mixed success of a US campaign against China’s largest tech company since 2018.

Citing national security concerns, the White House started by trying to curtail the sale of American software and circuitry to Huawei before finally enacting sweeping restrictions against its suppliers including TSMC.

 It’s that last salvo, a ban on the sale of ready-made, commercially available semiconductors, that finally knee-capped Huawei’s smartphone business and forced it to curtail device production, the people said. Representatives for Huawei and TSMC declined to comment.

But the Tiangang chip, designed in-house by secretive division HiSilicon, has proven pivotal to keeping the 5G business afloat.

Huawei had leaned on TSMC in the months before Washington shut that loophole and it can now continue to supply China Mobile Ltd., China Telecom Corp. and China Unicom — the carrier trio now aggressively building out a nationwide 5G network Beijing considers instrumental to driving the world’s No. 2 economy.

A China Mobile representative declined to comment for this story. A China Telecom spokesperson said the company will communicate any impact from curbs on Huawei but declined to comment on discussions about chip supply. Unicom representatives didn’t respond to requests for comment.

“The US has demonstrated an intense will to restrict Huawei’s ability to offer 5G technologies. The US government’s assertions of extraterritoriality have made it more difficult for Huawei to maintain access to critical components,” said Dan Wang, an analyst at Gavekal Dragonomics.

In 2012, just a third of Huawei’s revenue was generated in China — that closed in on two-thirds last year. “Huawei is more dependent on domestic sales due to both US pressure as well as its strong hold over the fast-growing China market.”

Huawei told Chinese wireless operators its component inventory was fully capable of supporting base station construction in 2021 and beyond despite US sanctions, according to people familiar with the matter. The company has started shipping 5G base stations without American components since at least the end of last year.

It’s unclear how long those stocks can last. Rotating Chairman Guo Ping said last month the company has “sufficient” inventory for its communications equipment business. But it’s seeking supplies for the smartphone unit, which on Thursday unveiled potentially its last major phone before a shortage of components forces a rethink of the device lineup.

“We are suffering from the U.S. government’s third-round ban. This unfair ban,” consumer business chief Richard Yu said during a live-streamed presentation.

Even assuming Huawei has cached enough silicon for Chinese carrier clients’ purposes, it may have had to make sacrifices in performance because of shortages in second-tier components. Resorting to less-sophisticated local alternatives may hinder areas such as power consumption rate, the people said. To rectify that, Huawei’s promised to compensate carriers for part of that additional electricity expense, they said. A typical 5G base station consumes roughly four times the power of a standard 4G model.
