Chinese smartphone maker Huawei’s third-quarter revenue jumped 27 percent, driven by a surge in shipments of smartphones launched before a trade blacklisting by the United States expected to hammer its business.

Huawei, the world’s biggest maker of telecom network equipment and the No. 2 manufacturer of smartphones, was all but banned by the United States in May from doing business with American companies, significantly disrupting its ability to source key parts.

The company has been granted a reprieve until November, meaning it will lose access to some technology next month. Huawei has so far mainly sold smartphones that were launched before the ban.

Its newest Mate 30 smartphone — which lacks access to a licensed version of Google’s Android operating system — started sales last month.

Huawei in August said the curbs would hurt less than initially feared, but could still push its smartphone unit’s revenue lower by about $10 billion this year.

The tech giant did not break down third-quarter figures but said Wednesday that revenue for the first three quarters of the year grew 24.4 percent to just over $85 billion.

Revenue in the quarter ended Sept. 30 rose to $23.3 billion, according to Reuters calculations based on previous statements from Huawei.

“Huawei’s overseas shipments bounced back quickly in the third quarter although they are yet to return to pre-US ban levels,” said Nicole Peng, vice president for mobility at consultancy Canalys.

“The Q3 result is truly impressive given the tremendous pressure the company is facing. But it is worth noting that strong shipments were driven by devices launched pre-US ban, and the long-term outlook is still dim,” she added.

The company said it has shipped 185 million smartphones so far this year. Based on the company’s previous statements and estimates from market research firm Strategy Analytics, that indicates a 29 percent surge in third-quarter smartphone shipments.
