Why did the Trump administration have such a different attitude towards refined copper, exempting it from import tariffs, while imposing a high 50% tariff on aluminum?
According to CCTV News, on July 30 local time, U.S. President Trump signed a notice announcing that starting August 1, only copper semi-finished products such as copper pipes, copper wires, and cables would be subject to a 50% tariff, while refined copper, including cathode copper and anode copper, which is mainstream in international trade, would be exempt.
This unexpected decision to tax only semi-finished products like copper wires, pipes, and sheets has shaken the copper market. Since the announcement on Wednesday, U.S. copper prices have fallen by more than 20%. In contrast, aluminum metal imported into the U.S. has faced a 50% tariff since June.

Behind this, major producers like Freeport-McMoRan lobbied that tariffs could weaken U.S. copper production and highlighted the importance of refined copper to U.S. manufacturing, leading to this exemption policy. Meanwhile, U.S. aluminum producers have strongly supported the tariff policy, believing it is crucial for protecting U.S. aluminum smelting capacity.
Additionally, electricity costs are also an important influencing factor, with different electricity cost structures determining the level of trade protection for each metal industry.
<h2>Aluminum Industry Actively Lobbied for Policy Support</h2>
According to media reports on Tuesday, U.S. aluminum producer Century Aluminum has been a strong supporter of the tariff policy, believing it is vital for protecting U.S. aluminum smelting capacity. The company stated in a June announcement:
<blockquote>
Century Aluminum appreciates President Trump’s unwavering defense of key metals in U.S. production by raising aluminum tariffs to 50%.
</blockquote>
The disadvantage in electricity costs has led to a significant shrinkage of U.S. aluminum smelting capacity. Currently, there are only 4 active aluminum smelters in the U.S., down from 23 in 1995. According to data from the U.S. Geological Survey, U.S. primary aluminum production fell from 3.35 million metric tons in 1995 to 1.6 million metric tons in 2015, and further declined to 670,000 metric tons last year.
This decline in capacity provides a strong argument for the aluminum industry to seek trade protection and explains why aluminum metal can receive a high 50% tariff protection.
<h2>Copper Industry Lobbying Power &#34;Facilitated Exemption&#34;</h2>
The exemption of tariffs on refined copper reflects its importance to American manufacturing and the industry's influence, including major producer Freeport-McMoRan. The company warned earlier this year in response to the U.S. government's inquiry into copper import tariffs that tariffs could undermine U.S. copper production.
Freeport-McMoRan pointed out in its submitted comments:
<blockquote>
The global trade war could lead to a slowdown in economic growth. A slowdown in U.S. or global economic growth would negatively impact copper prices, and due to the high cost structure of domestic copper production, this could threaten the viability of the domestic copper industry.
</blockquote>
This argument strategy contrasts sharply with the aluminum industry. The copper industry emphasizes the adverse effects of the trade war rather than seeking protection; the aluminum industry actively seeks tariff protection to survive. The different cost structures and market positions determine the starkly different lobbying strategies and policy outcomes of the two industries.
<h2>Differences in Electricity Costs Determine Policy Tilt</h2>
Electricity costs account for different proportions in the U.S. metal smelting industry, directly influencing the government's tariff policy orientation. According to Macquarie Bank, energy costs account for approximately 50% and 30% of total costs for primary aluminum and copper production, respectively.
U.S. aluminum smelters face higher electricity costs than copper producers, giving the aluminum industry a stronger economic rationale in seeking trade protection. Analysts point out that compared to the UAE, Bahrain, and the world's largest producer, China, U.S. electricity costs are at a disadvantage.
Macquarie analyst Marcus Garvey stated that there is no economic basis for building any new aluminum smelting capacity without significant intervention. Even with intervention, it may not be sufficient. The main difficulty faced by investors is the challenge of obtaining competitive long-term electricity procurement agreements

PHUN

The American copper giant lobbied that tariffs could weaken U.S. copper production and the importance of refined copper to U.S. manufacturing, which contributed to this exemption policy. Meanwhile, U.S. aluminum producers have strongly supported the tariff policy, believing it is crucial for protecting the remaining capacity of the U.S. aluminum smelting industry. Additionally, electricity costs are also an important influencing factor

- The Trump administration imposed a 50% tariff on aluminum while exempting refined copper from import duties, reflecting differing industry lobbying efforts.  
- Major copper producers like Freeport-McMoRan argued that tariffs could harm U.S. copper production, emphasizing its importance to manufacturing, while aluminum producers supported tariffs to protect their dwindling capacity.  
- The disparity in electricity costs between the two industries significantly influenced these policy decisions, with aluminum facing higher energy expenses, making a stronger case for trade protection.

Why are copper spared while aluminum cannot escape the disaster? Why does Trump's tariff policy show favoritism?
