Rusal halts alumina shipments from Ukraine

The reports come after U.S. President Donald Trump and Canadian Prime Minister Justin Trudeau discussed the tariffs earlier on Friday.

The metal touted for its environmental benefits, particularly in the manufacture of lighter cars and trucks, has a big problem with storing its toxic by-products.

Three-month aluminium fell to $1,784 a tonne on Thursday, the lowest since January 2017.

The company says demand for its products had not been impacted by the US-China trade dispute.

The latest order aims to discourage foreign companies and countries that may still be trying to maintain business with Iran.

In April, Rusal landed a major equity and supply deal with Braidy Industries, which is building the first greenfield aluminium rolling mill in the United States in 37 years.

Base metals have had a shaky start to 2019, with a cautious Q1 advance giving way to an April drop on uncertainty about the global economy.

The new offering comes five years after a similar product fizzled on the Singapore Exchange (SGX).

Industrial metal markets are taking a breather as they await tangible evidence that China's latest stimulus package is feeding through to a flagging manufacturing sector.
