(Bloomberg) -- The Biden administration is considering a complete ban on Russian aluminum -- long shielded from sanctions due to its importance in everything from automobiles and skyscrapers to iPhones -- in response to Russia’s military escalation in Ukraine.

The White House is eyeing three options: an outright ban, increasing tariffs to levels so punitive they would impose an effective ban, or sanctioning the company that produces the nation’s metal, United Co. Rusal International PJSC, according to people familiar with the decision-making.

Such a move would have wide-reaching repercussions for the globally traded aluminum market, potentially forcing consumers in the US and other countries into a rush to find replacement metal. 

The globally traded price of the metal surged on the news of a possible ban. Aluminum on the London Metal Exchange rose 1.5% to $2,340 a ton on Thursday as of 8:42 a.m. in Shanghai, after surging as much as 7.3% in the prior session for one of its biggest intra-day gains amid concerns that such a move would crimp availability. American producer Alcoa Corp. jumped as much as 8.6% while trading of US producer Century Aluminum Co. halted after a sudden move higher.

Russia is the world’s second-largest producer after China of aluminum, which is crucial to most heavy industries. In the US alone, Russian supplies traditionally account for some 10% of total aluminum imports, with data showing Russia was the third-largest exporter to the US in August. 

The ban is being considered in response to Russia’s missile attacks on Kyiv and other Ukrainian cities this week that damaged key infrastructure and civilian sites.

A White House official said all options were under consideration but there was no immediate movement on the topic. The Commerce Department and Rusal’s press service did not immediately respond to requests for comment. 

The administration at the beginning of the war held off sanctioning Russian aluminum, fearing it could disrupt global suppliers, people familiar with the matter said at the time. But with the ongoing war now in its eighth month, there are fewer products left for the US and Ukraine’s allies to ban in response to Russia’s escalations. The discussion by the White House has been ongoing for weeks.

US officials had previously disclosed concern that sanctions impacting aluminum supply could drive up the price of the metal. 

Aluminum markets descended into chaos in 2018 after the US sanctioned Rusal, with investors and suppliers concerned about supply, plant closures and work-force reductions. The penalties were lifted early in 2019 after an agreement with the US Treasury Department’s Office of Foreign Assets Control forced Rusal billionaire founder Oleg Deripaska to relinquish control over the company.

Rusal has said a ban would destabilize metal markets around the globe.

The debate within the metals industry over how to address Russian supplies has intensified in recent weeks.

The London Metal Exchange, the largest industrial metals exchange in the world, last week launched a discussion paper to determine if the Russian metal should be banned from the bourse.

Alcoa, the largest US aluminum producer, last month sent a letter to the London Metal Exchange that it shouldn’t allow trading of the Russian metal, raising fears it could be dumped to suppress global prices.

The chief executive of Rio Tinto Plc, the world’s second-largest mining company, last month also raised the alarm that unfettered flow of Russian aluminum into the US was making North American producers less competitive.
