Tariff Threats Trigger Transatlantic Copper Pricing Differences

Copper prices are experiencing significant differences between the United States and global markets due to concerns over potential import tariffs. As speculation grows that U.S. President Donald Trump may impose tariffs on copper imports, traders and manufacturers are closely watching price movements.

The gap between copper prices on the Chicago Mercantile Exchange (CME) and the London Metal Exchange (LME) has widened considerably. Currently, CME copper is trading at a premium of over $1,000 per metric ton compared to LME prices. This is mainly due to fears that the U.S. government may apply tariffs similar to those imposed on aluminum and steel.

Many traders believe a 10% tariff is already priced into the market. However, if the U.S. imposes a higher tariff—possibly 25%—the price difference could increase further. The United States heavily relies on copper imports, with over 800,000 metric tons of refined copper brought in during 2024, almost equal to the country’s domestic production of 850,000 metric tons. This makes the market highly sensitive to any changes in trade policy.

A tariff on copper could create serious disruptions in supply chains. The U.S. imports approximately 45% of the copper it consumes, meaning higher tariffs would raise costs for businesses that rely on copper-based products. Companies that manufacture items like copper wire for automotive parts might be forced to move their production from Mexico to Asia, where costs may be lower.

Additionally, tariffs could shift copper scrap trade patterns. The U.S. processes large amounts of copper scrap from Mexico and Canada, but new tariffs could encourage these countries to sell their scrap to China instead. This would make it harder for American recyclers to obtain the raw materials they need, affecting the secondary copper production industry.

Copper is a key material in industries such as construction, electronics, and renewable energy. Because it is widely used, copper prices often indicate overall economic health, earning the nickname “Doctor Copper.” If the U.S. imposes tariffs, other countries might respond with trade barriers of their own, reducing global demand. While copper prices have increased by 7% in early 2025 due to strong demand expectations, a trade war could reverse this trend.

Should the tariffs take effect, the price difference between U.S. and global copper markets will likely persist. The market is currently pricing in some level of tariff risk, but if new trade barriers significantly slow down consumption, copper prices could become even more volatile.

The ongoing tariff concerns are driving a wedge between U.S. and international copper prices. The future of copper pricing will largely depend on government policies and global trade responses.

Entities like Torr Metals Inc. (TSX.V: TMET) in the copper value chain will be monitoring how the tariff threats play out and how commodities markets respond to the changing policy decisions.
