Reuters reported that Russian aluminium producer Rusal, under US sanctions since April, reduced its aluminium exports by 8.6% in September compared to the previous month to 264,400 tonnes. Between January and September, Rusal’s aluminium exports totalled 2.1 million tonnes, down 0.6 percent YoY.

Rusal, the world’s largest aluminium producer outside China, saw its exports and supply chain crippled after Washington put the company and co-owner Oleg Deripaska on a blacklist, seeking to punish Russia for alleged meddling in US elections. US customers must wind down business with the company by Nov. 12, according to the sanctions.

Last year, Rusal, in which Deripaska’s En+ is a controlling shareholder, sold 4 million tonnes of aluminium, of which 42 percent was shipped to Europe.
