April 2018 has seen the metals markets thrown into turmoil by the US imposition of sanctions on United Company Rusal.

Appropriate compliance procedures, including due diligence as to ownership structures, should be followed.

Parties should also seek legal assistance in the event of contractual disputes arising whether directly or indirectly from the knock-on impact of sanctions.
