## Rio Tinto, Century Aluminum Hike US Premiums 12% as Iran War Disrupts Middle East Supply
Two of the world's leading aluminum producers have sharply increased costs for American manufacturers. Rio Tinto Group and Century Aluminum Co. have raised the premium, or surcharge, on a key semi-processed aluminum product in the United States by approximately 12% in recent weeks. This significant price adjustment is a direct response to supply chain disruptions stemming from the ongoing conflict involving Iran, which has severely hampered imports of the metal from the Middle East to the US market.

The move targets a specific, essential input known as P1020 aluminum, a primary form of the metal used in a vast range of finished goods. The decision by these major suppliers signals acute pressure on a critical industrial supply line. The people familiar with the matter indicate the war's impact on shipping and trade routes from the Middle East is the primary catalyst, forcing producers to pass on higher logistical and risk costs to downstream customers.

This premium hike will immediately increase production costs for a wide swath of US industries, from automotive and construction to packaging and consumer durables. It represents a tangible, early economic consequence of geopolitical instability translating into market volatility. The adjustment places additional inflationary pressure on manufacturers already navigating a complex global landscape, with the risk of these costs eventually filtering through to consumer prices if the supply constraints persist.
