Copper outlook: a 12-month high, new duties and pass-through requests
Copper and brass mill shapes are at a 12-month high and copper now falls under Section 232. What drives copper costs, where it hides in your spend, and how to handle supplier increases.
Map copper-heavy parts and require a cost breakdown with every pass-through request.
◷ Before first-quarter price lettersKey takeaways
- Copper and brass mill shapes were at a 12-month high in August, up 20.9% on the year.
- Copper and its derivatives are covered by the April 2026 Section 232 metals proclamation.
- Copper hides in wire, cable, motors, transformers, HVAC and electronics, so exposure is wider than direct metal spend.
- Copper is also a top target for cargo thieves, with metal thefts up sharply in 2026.
- Our move: map copper-heavy parts and require a cost breakdown with every pass-through request.
How the copper market works
Copper is priced off global exchanges, and most products made from it carry a metal component that moves with that price plus a fabrication charge. Wire and cable makers, for example, usually publish a copper-based price adjustment or quote with a “copper base” that resets with the market. Brass mills price similarly, with a metal value and a conversion charge.
For procurement teams, the important point is where copper hides. Direct purchases of copper rod, tube or sheet are only part of the exposure. Copper sits inside motors, transformers, switchgear, HVAC equipment, cable assemblies and electronics, and suppliers of those products pass metal changes through, often with a delay.
What is driving prices now
Demand from electrification. Grid upgrades, data centers, electric vehicles and electrified equipment all use large amounts of copper, and new mines take many years to develop. That structural gap is why copper has held up even when other metals eased.
Trade measures. Copper and copper derivatives are covered by the April 2026 Section 232 metals proclamation, adding a duty layer to imported products.
Price momentum. U.S. producer prices for copper and brass mill shapes were at a 12-month high in August, up 20.9% on the year, according to our Cost Pressure Monitor. ISM respondents also listed copper among commodities rising in price in September.
Where the negotiating leverage sits
Suppliers have the edge. With prices at a high and demand firm, pass-through requests are coming. Procurement’s leverage comes from insisting on transparency: copper weight, reference price and base, so that only the true metal effect passes through and reverses when prices fall.
Supply risk: what could go wrong
- Pass-through stacking, where suppliers add metal surcharges on top of general increases that already included metal.
- Lead times for copper-heavy equipment such as transformers and switchgear, which ISM respondents reported in short supply.
- Theft. CargoNet recorded metal thefts rising from 54 to 80 incidents year over year in the second quarter, with copper the main target. See our cargo theft coverage.
How to buy it now
- Map copper content. For your top electrical and mechanical categories, ask suppliers for copper weight per unit.
- Agree a metal adjustment formula. Reference price, base, timing and both-direction adjustment.
- Separate metal from general increases. Don’t accept a general increase that already includes metal plus a separate surcharge.
- Secure long-lead equipment early. For transformers and switchgear, order date matters more than a few points of price.
- Protect shipments. Use vetted carriers and tracking for high-value copper loads.
What to watch
- Monthly producer price data and exchange prices.
- Changes to Section 232 derivative coverage.
- Lead times on copper-intensive electrical equipment.

Our coverage of copper and brass
- Cargo theft losses more than doubled to $304.6 million in the second quarter even as incidents fell 26%Organized groups are stealing fewer loads but choosing more valuable ones, especially copper and other metals and enterprise technology. The average stolen load was worth $564,009, according to Verisk CargoNet.
Questions procurement teams ask
Why are copper prices rising?
Copper demand is growing from electrification, data centers and grid investment, while new mine supply is slow to arrive. In the U.S., Section 232 coverage of copper and derivatives adds a trade cost on top.
Which purchases contain the most copper?
Wire and cable, motors, transformers, switchgear, HVAC coils, plumbing and many electronic assemblies. For these, copper can be a large share of cost, so metal price changes pass through quickly.
How should I respond to a copper surcharge?
Ask for the copper weight per unit, the reference price used and the base price in your contract. Only the copper share should move, and the surcharge should fall when the reference price falls.
