Why Is the US Copper Scrap Market Shifting to LME Pricing?
The US copper scrap market is undergoing a fundamental transformation in pricing methodology, moving away from traditional COMEX-based pricing toward London Metal Exchange (LME) benchmarks. This shift represents a seismic change in how the industry values materials and conducts transactions, with implications reaching across the entire supply chain.
Market Volatility Driving Fundamental Change
The recent extreme volatility in COMEX copper futures has created an untenable situation for many market participants. In early July 2025, COMEX copper contracts experienced unprecedented price swings, reaching a peak of $5.6855 per pound on July 8 before fluctuating dramatically to $5.4865 on July 9, $5.591 on July 10, and $5.6045 on July 11.
"The panic-button reaction following the tariff announcement caused COMEX prices to react fast and furious," explained Marex analyst Ed Meir, highlighting how political uncertainty has exacerbated market instability.
These wild price swings created severe cash flow challenges from margin calls, straining operational capabilities across the industry. Many businesses found themselves unable to maintain traditional trading patterns under such volatile conditions.
Trade Policy Disruptions Accelerating the Transition
The implementation of a 50% tariff on copper imports announced by the administration in early July 2025, coupled with additional 30% tariffs on Mexican and EU imports effective August 1, has dramatically altered market dynamics. This policy shift created immediate uncertainty about whether copper scrap would be included in Section 232 tariff provisions.
"The disconnect between COMEX and LME creates immense pressure on pricing, especially for those of us handling international transactions," noted one prominent scrap trader.
The Recycled Materials Association (ReMA) is actively monitoring developments regarding potential exemptions for USMCA-compliant goods, adding another layer of complexity to an already challenging market environment.
Global Market Alignment Benefits
Perhaps most significantly, the transition to LME pricing addresses a fundamental misalignment between domestic and international copper markets. While COMEX has historically dominated US copper pricing, the global market predominantly uses LME as its benchmark.
"The global market is tethered to the LME," emphasized one copper scrap market participant. "For those of us focused on exports, switching to LME pricing means we're finally speaking the same language as our international trading partners."
This alignment delivers particular benefits for export-focused businesses, who have long struggled with the complexities of translating COMEX-based pricing when selling internationally. The historical arbitrage gap between the two exchanges has reached record levels of approximately $2,500-2,700 per tonne according to market analysis from Ed Meir, creating pricing inefficiencies that impede smooth market function.
How Are Discount Formulas Changing?
The shift from COMEX to LME pricing is forcing a comprehensive recalculation of the discount formulas that have long defined copper scrap valuation. This transition period has created temporary market disruptions as participants adapt to new pricing structures.
Impact on Traditional Pricing Structures
Copper scrap has traditionally been priced as discounts to COMEX futures contracts, with the discount reflecting material quality, processing requirements, and market conditions. Recent market volatility has caused these discounts to widen dramatically as participants hedge against uncertainty.
According to Fastmarkets assessments, No. 1 copper discounts increased from $0.50-0.55 to $0.78-0.83 per pound between July 2 and July 9, 2025. Similarly, No. 2 copper discounts rose from $0.85-0.90 to $1.25-1.30 per pound during the same period.
These widening discounts reflect both the volatility in underlying futures prices and the market's adjustment to new pricing mechanisms. Price assessment methodologies have evolved to accept both LME and COMEX discount data, prioritizing the exchange where the majority of market activity occurs.
Transition Challenges for Market Participants
The implementation timeline for switching to LME pricing varies significantly across the industry. While some export-focused businesses have already completed the transition, others with existing contracts tied to COMEX rates require renegotiation, potentially extending the process for several weeks.
Mills appear to be leading the shift, with many now refusing COMEX-based formulas in favor of LME references. This has created a bifurcated market where some transactions occur with LME pricing while others remain tied to COMEX until contracts expire or are renegotiated.
"Many buyers have paused spot purchases on COMEX spreads entirely," reported one dealer. "They're waiting for the dust to settle before committing to new transactions."
Price Stability Expectations
Despite current turbulence, market participants generally anticipate an eventual normalization of discount rates once the transition period concludes. The consensus view holds that current extreme discount levels are temporary responses to exceptional volatility rather than permanent structural changes.
"We expect discounts to return to some more normalcy once everyone adjusts to the new pricing benchmark," predicted one scrap processor. "But that may be wishful thinking given the ongoing policy uncertainty."
Industry veterans note that pricing transitions historically create temporary dislocations before markets reestablish equilibrium at new levels. The adaptation period is expected to last several weeks as new pricing norms become established across the supply chain.
Who Benefits from the LME Pricing Shift?
The transition to LME-based pricing creates winners and losers across different segments of the copper scrap market, with implications varying by business model and market focus.
Advantages for Exporters
Export-focused businesses stand to gain significant advantages from the shift to LME pricing. With over 80% of US copper scrap exported according to ReMA data, alignment with international pricing standards simplifies transactions and reduces risk.
"We have moved to quoting off LME for everything," confirmed one major scrap seller. "Some material stays domestic on COMEX pricing, but the rest is exported off LME."
Key benefits include:
- Simplified trading with international partners using consistent price benchmarks
- Reduced currency and exchange rate complications when hedging transactions
- Better alignment with global market conditions for price discovery
- Improved risk management through appropriate hedging instruments
LME contracts also offer greater efficiency for exporters dealing in multiple currencies, reducing the basis risk that occurs when hedging international sales against COMEX futures.
Domestic Consumer Perspectives
Mills and brass ingot makers are actively driving the transition to LME pricing, recognizing potential benefits for their operations. Major US mills including Wieland and Mueller have taken leadership positions by refusing COMEX-based formulas in new contracts.
For domestic consumers, the shift offers:
- Potential for more stable supply chains with consistent pricing mechanisms
- Reduced exposure to COMEX-specific market speculation
- Better alignment with their own metal hedging strategies
- Simplified procurement processes for international operations
However, adaptation challenges during the transition period have temporarily disrupted normal trading patterns as new discount formulas are established.
Market Participant Reactions
Industry responses to the pricing shift vary considerably, reflecting different business models and market positions. Export-focused businesses have generally embraced the change, while some traders with sophisticated COMEX trading operations express reservations.
"COMEX is speculation for a reason," argued one trader. "It provides valuable forward price signals that LME sometimes lacks."
Despite these varied perspectives, the overwhelming industry consensus acknowledges the inevitability of the transition. "Everyone is going to switch to LME-based formulas, you can see it coming," predicted one scrap processor.
Most participants express pragmatic flexibility rather than ideological preferences. "We will go with what our consumers want," summarized one dealer, capturing the market's client-centered approach to the transition.
What Does This Mean for the Future of US Copper Scrap Trading?
The shift to LME pricing represents more than a technical adjustment; it potentially reshapes fundamental market structures and trading relationships across the copper scrap industry.
Long-Term Market Structure Implications
The current transition may signal a permanent shift in pricing benchmarks that extends beyond temporary market volatility. As LME pricing becomes embedded in contracts and trading relationships, the market's center of gravity could permanently shift away from COMEX-based formulas.
This evolution creates potential for:
- Development of new discount formulas specifically calibrated to LME references
- Changing relationships between domestic and export markets as pricing aligns
- Realignment of trading patterns to accommodate global pricing mechanisms
- New arbitrage opportunities between physical scrap and LME futures
"The market structure is evolving before our eyes," noted one industry veteran. "Companies that adapt quickly will find opportunities, while those resisting change may struggle."
Supply Chain Resilience Considerations
The pricing transition raises important questions about domestic material retention versus export opportunities. If tariffs eventually include copper scrap, domestic consumers may gain leverage in negotiations, potentially altering traditional material flows.
Key considerations include:
- Impact on US manufacturing competitiveness if pricing becomes more stable
- Potential for more predictable supply chains benefiting downstream industries
- Adaptation strategies required across different tiers of the value chain
- Long-term competitive positioning of US firms in global markets
Companies are developing strategic responses based on their assessment of how permanent these changes will prove to be. "We're planning for a fundamentally different market going forward," explained one major processor.
Market Monitoring Metrics
Industry participants are establishing key metrics to track the transition's progress and assess its impact on market dynamics:
- Arbitrage spreads between LME and COMEX as indicators of market alignment
- Discount rate stabilization timelines as new pricing norms establish
- Export volumes and destinations for evidence of changing trade flows
- Evolution of price assessment methodologies to reflect market practices
These metrics will provide vital feedback on whether the transition achieves its intended goals of greater price stability and market efficiency.
How Should Market Participants Navigate the Transition?
The shift to LME pricing requires strategic adaptation across all levels of the copper scrap supply chain. Companies must balance short-term operational challenges against long-term strategic positioning.
Strategic Adaptation Approaches
Successful transition strategies typically include:
- Gradual implementation of LME-based pricing starting with new contracts
- Maintaining flexibility during the transition period to accommodate both pricing systems
- Developing new risk management strategies appropriate for LME-based pricing
- Building relationships with trading partners experienced in LME markets
"Those who've worked in international markets have a significant advantage right now," observed one export specialist. "Their experience with LME pricing gives them a template for domestic adaptation."
Companies with predominantly domestic focus face steeper learning curves but can leverage industry associations and trading partners for guidance during the transition.
Risk Management Considerations
The shift to LME pricing necessitates adjustments to established risk management practices:
- Hedging strategies require adaptation for different exchange mechanisms
- Understanding LME contract specifications and delivery requirements becomes essential
- Monitoring basis risk between physical markets and exchange prices takes on new importance
- Working capital and cash flow management strategies need recalibration
"The mechanics of LME hedging differ significantly from COMEX," explained one risk management consultant. "Companies need to invest in training and potentially new systems to manage these differences effectively."
Firms like JX Nippon are documenting LME-based pricing specifically in new contracts to avoid disputes, establishing clear risk allocation between parties during the transition.
Communication Best Practices
Clear communication emerges as a critical success factor during the transition period:
- Transparent discussions with trading partners about pricing preference changes
- Clear documentation of pricing basis in contracts and purchase orders
- Regular reviews of discount formulas to address market shifts
- Industry collaboration to establish new market norms
"Overcommunication is essential right now," advised one industry leader. "Making assumptions about which pricing basis applies creates unnecessary disputes in this environment."
Trade associations are facilitating information exchange about best practices, helping establish consistent approaches across the industry.
FAQs About the US Copper Scrap Market's Pricing Transition
What is causing the extreme volatility in COMEX copper prices?
Recent trade policy announcements, including a 50% tariff on copper imports and additional 30% tariffs on Mexican and EU goods effective August 1, 2025, have triggered significant market reactions. This political uncertainty, combined with speculative trading, has created unprecedented price movements in COMEX copper contracts, with prices swinging dramatically from $5.6855 per pound on July 8 to $5.4865 on July 9 before rebounding.
Will copper scrap be included in the new tariff provisions?
Uncertainty persists regarding scrap inclusion in Section 232 provisions. Adam Schaffer, ReMA Vice President, confirms they are "monitoring developments closely" but final determinations remain pending. USMCA-compliant materials may receive exemptions, creating additional complexity for cross-border trade. Companies should prepare contingency plans for both inclusion and exclusion scenarios.
How quickly are companies transitioning to LME pricing?
The transition timeline varies significantly by market segment. According to industry polling, approximately 70% of exporters had switched to LME pricing by mid-July 2025, while domestic mills are transitioning through August. Companies with existing COMEX-based contracts are planning transitions over several weeks as contracts expire or are renegotiated. Mills appear to be leading the shift, with some already refusing COMEX-based pricing formulas.
Does LME pricing solve all the market's volatility issues?
While LME pricing may provide better alignment with global markets, it is not a complete solution to market volatility. Some industry participants note that COMEX serves a valuable speculative function that can provide forward-looking price signals. The transition addresses structural misalignments between domestic and international markets but cannot eliminate all uncertainty, particularly amid ongoing trade policy volatility.
How are copper scrap discounts calculated?
Copper scrap is typically priced as a discount to either COMEX or LME futures contracts, with the discount reflecting quality differences, processing requirements, and market conditions. For example, No. 1 copper discounts increased from $0.50-0.55 to $0.78-0.83 per pound between July 2-9, 2025. As the market transitions, assessment methodologies are accepting data for both LME and COMEX discounts, prioritizing the exchange where the majority of activity occurs.
