Corporations’ deepening issues over copper come as they’re already grappling with the upper prices of Trump’s escalating commerce warfare, with US gross sales of merchandise from vehicles and vehicles to building tools hit by coverage uncertainty.
Analysts warn the implications to costs and demand of completely increased copper tariffs can be critical for the reason that steel is broadly utilized in electrical autos, chips and defence tools, in addition to family home equipment and wiring.
The US depends closely on imports of the steel, which accounted for about 53 per cent of its copper demand in 2024, based on Morgan Stanley.
John O’Leary, North American boss of Daimler Truck, stated firms had change into more and more annoyed since they’d anticipated readability on the tariff coverage by now. The group this week reported a 20 per cent drop in second-quarter truck gross sales in North America as logistics firms held off purchases because of the uncertainty.
“Clearly, no tariffs are greatest, but when there’s going to be one thing, simply inform us what it’s and we will get on with life and begin determining how you can cope with it,” O’Leary stated.
Till now, O’Leary stated, the corporate had pushed again towards suppliers which have invoked tariffs as power majeure in an effort to boost costs on long-term buying offers on aluminium and metal.
“The contracts we’ve had have protected us up thus far, however actually sooner or later in time they begin to run out after which renegotiations happen.”
The White Home has not launched particulars of the tariffs, together with whether or not they’ll apply to semi-finished copper merchandise akin to wires and rods, and whether or not restrictions on exports of copper scrap may additionally be put in place.
Along with long-term contracts, there was a rush of copper into the US this 12 months on expectations of upper tariffs. Because of this, analysts say finish customers of copper are unlikely to be hit with the complete impression till the producers’ personal warehouses run out of their provides.
“I’d say there may be six to 9 months to make use of that buffer constructed from additional shopping for of refined copper, after which that’s when you may begin to see the complete value of the 50 per cent tariff,” stated Amy Gower, commodities strategist at Morgan Stanley.
Whereas the pre-buying means American industrial firms have wholesome inventories of the steel for now, ultimately they “might want to take increase costs to offset the upper copper prices, which may result in demand destruction down the highway”, stated Jake Seltz, a portfolio supervisor at Allspring World Investments.
Corporations and buyers are nonetheless hopeful that the Trump administration will accept decrease copper tariffs. The arbitrage between US costs and people elsewhere has solely blown out to about 28 per cent, suggesting the market doesn’t totally imagine the 50 per cent tariffs will come into power.

“My greatest guess is that the realisation of the impression of a 50 per cent tariff on copper will hopefully be understood earlier than it’s really felt,” stated James Cordier, chief govt and head dealer at Florida-based funding group Various Choices.
Barclays estimated {that a} 50 per cent tariff may add as much as $110 to the price of a petroleum automobile and as a lot as $700 to an electrical automotive for the reason that steel is utilized in wiring harnesses in addition to batteries, motors and inverters.
Nevertheless, the impression is prone to filter by not directly for carmakers, since it’s suppliers that usually buy the steel. Trump has additionally promised that the auto business, which faces a 25 per cent tariff on imports of foreign-made autos, is not going to be stacked with further levies on the metals.
Throughout a pre-earnings briefing with analysts on Wednesday, Germany’s BMW described the impression from increased copper tariffs as “negligible”, based on Bernstein.
Aerospace Industries Affiliation, a US commerce group, has estimated that it might take as much as 10 years to search out, certify and swap to a brand new provider of important minerals due to the complicated nature of aerospace and defence provide chains.
“Within the close to time period, we encourage the administration to keep up entry with trusted sources of those minerals to keep away from a value spike that can be felt most by our small and mid-size suppliers,” stated Dak Hardwick, AIA vice-president of worldwide affairs.
How copper costs will pattern over the medium time period can also be unclear. Analysts anticipate the worldwide value on the London Metallic Alternate to hunch as soon as the arbitrage trades run their programs. If costs stay excessive, customers may swap to various supplies akin to aluminium, which might trigger copper costs to say no, based on SMBC Nikko.
For some, the copper tariffs current a chance. Cable maker Prysmian, the most important company purchaser of copper outdoors China, stated it noticed the tariffs as being “constructive” for the corporate even because it awaited extra particulars on what merchandise the levies will apply to.
The Milan-listed firm already makes the vast majority of its US merchandise within the US — sourcing copper from Freeport McMoran and from recycled scrap materials. It then makes the wire and cable at its personal services within the US.
“We’re a lot much less uncovered than the nation and the remainder of the sector to imports,” stated Maria Cristina Bifulco, head of investor relations at Prysmian, noting that it imports solely a couple of third of its US wants.
Nevertheless, copper costs are handed by on to prospects, primarily based on benchmark costs, and Bifulco acknowledged that increased copper costs may hit demand.
“In our case, we move by to the purchasers the uncooked materials costs. So the true impression of the tariff isn’t on us, it’s on the ultimate prospects. The uncooked materials value traits are inclined to affect the demand behaviour.”
