Glencore Trades With Iran Even as Competitors Depart

Glencore Xstrata Plc, the largest publicly traded commodities supplier, is conducting business with Iran even as competitors abandon the country, potentially drawing scrutiny from regulators.

Documents filed with the U.S. Securities and Exchange Commission by Century Aluminum Co., in which Glencore owns 41.8 percent, show non-U.S. affiliates of Glencore “entered into sales contracts for agricultural products as well as purchase contracts for metals with Iranian entities” last quarter.
