This is the letter I received from Copper and Brass Sales this morning, this accurately explains (IMO) the efforts to restart the copper industry in the USA.

Navigating the Storm: Copper Tariffs
On August 1, 2025, a sweeping new US tariff took effect under Section 232 of the Trade Expansion Act, imposing 50% duties on all semi-finished copper products, including wire, tubing, sheets, rods, and copper based fittings. Notably, this does not include refined copper, copper ore, or scrap copper which currently remain exempt, creating implications for manufacturing, procurement, and strategic sourcing that companies already feel.
These new tariffs, first announced in early July 2025, have far-reaching implications for manufacturers, processors, and end-users across sectors as diverse as aerospace, electronics, energy, and construction. For companies that rely on high-performance copper alloys, the time to prepare is now.
At Copper and Brass Sales, we understand that staying ahead of regulatory shifts is essential to helping our customers accelerate performance and increase value. Here’s what you need to know about the changes and how working with a solutions partner can help mitigate the impact.

A Policy with Global Implications and Domestic Opportunity
The decision to implement the copper tariff stems from a February 2025 executive order that triggered a national security investigation into US dependency on foreign copper. As reported by Reuters and The Washington Post, the Trump administration cited strategic vulnerability in critical infrastructure and defense supply chains, pointing to underutilized domestic refining and processing capacity.
According to government officials involved in the Section 232 process, the goal is to reinvigorate US copper production, particularly in copper mining regions like Arizona, where development has stalled due to global price pressures. The tariff serves both a protectionist and nationalistic purpose: reduce reliance on imports, boost domestic jobs, and ensure that copper remains available for national defense, energy transition, and technological growth.
Expanding domestic copper capacity involves developing new mines and restarting stalled projects, particularly in copper-rich regions like Arizona, as well as building and upgrading smelting and refining facilities that have been underutilized for decades. These efforts require years of permitting, infrastructure development, workforce training, and capital investment before new capacity can meaningfully supply US manufacturers. Ramping up production is not a quick fix; it will take sustained coordination between government, private industry, and local communities to meet growing demand from sectors such as aerospace, electrification, and advanced manufacturing. The intent is to create a stronger, more self-reliant US copper supply chain, however, realizing that goal will require long-term commitment well beyond the initial tariff implementation.
Impact Across Industries
The 50% copper tariff on imported semi-finished copper products is already producing a measurable impact across key sectors of the US economy. From precision components in aerospace to high-volume wiring in construction, industries that rely on copper-intensive parts are facing cost inflation, sourcing constraints, and operational recalibration. While the long-term policy goal is to drive domestic investment, the near-term result is a shift in supply chain dynamics, forcing manufacturers, engineers, and procurement teams to rethink how and where they source critical copper-based materials. Some industries are feeling the more immediate impact sooner than others. Manufacturers that rely on copper-intensive components, especially those sourced globally, must now reassess their sourcing models to maintain control over quality, timelines, and costs.
Aerospace and Defense
Copper alloys play a crucial role in aerospace applications, from wiring harnesses and hydraulic lines to landing gear and engine components. Defense manufacturers, too, rely on specialty copper grades for radar, guidance systems, and naval hardware. While the recent tariff excludes raw copper and cathodes, allowing upstream material inputs to remain duty-free, a duty represents the actual cost paid by importers at the border because of the tariff. In other words, the tariff establishes the policy; here, a 50% rate on semi-finished copper imports, while the duty is the financial obligation calculated from that rate. For example, a shipment of semi-finished copper valued at $100,000 would generate a $50,000 duty under the new tariff. This added expense still poses significant cost challenges for fabricated parts and finished components sourced from abroad.
Companies that rely on imported tubing, bars, or machined copper assemblies are likely to see increased procurement costs and tighter lead times. This is especially true for manufacturers without strong domestic supplier relationships or localized processing capabilities.
