The Chinese telecoms giant has asked for the US Court of Appeal to overturn the US Federal Communications Commission's decision to stop rural mobile providers using a $8.5 billion government fund to purchase its equipment.
The company's chief legal officer, Song Liuping, told reporters: "The US government has never presented real evidence to show that Huawei is a national security threat. That's because this evidence does not exist."
The legal challenge comes after Huawei launched similar action back in May as the firm opposed a decision to ban US government agencies from buying its equipment.
As reported by the BBC, Washington has been pressuring other nations in order to stop Huawei from building their important 5G telecoms infrastructure.
UK Prime Minister Boris Johnson said this week he wanted to ensure the country could continue to co-operate with the US over intelligence sharing.
He explained: "On Huawei and 5G, I don't want this country to be unnecessarily hostile to investment from overseas.
"On the other hand, we cannot prejudice our vital national security. Nor can we prejudice our ability to co-operate with other vital... security partners - and that will be the key criteria that informs our decision about Huawei."
