Steel, Aluminum & Rare Earth Volatility: A Mid-2026 Reality Check for Procurement Teams

Steel, aluminum, and rare earths are facing three different forms of cost volatility in 2026. Steel and aluminum tariffs now reach 50%, while NdPr prices have risen 138% year to date. Steel faces higher U.S. tariffs and broader customs-value exposure. Aluminum has split into a global LME benchmark and a much higher U.S. physical-market cost. Rare earths face sharper volatility driven by concentrated supply and export licensing. That’s what commodity procurement looks like in 2026: managing cost, availability, and supply risk across three materials that no longer move together.

This article is a 2026 commodity procurement risk data snapshot. It presents the latest steel, aluminum, and rare-earth price and policy data, explains the forces behind the changes, where costs are moving, and translates them into practical procurement actions.

2026 Commodity Snapshot

Steel: What’s Actually Changed in 2026

The U.S. steel regime became materially more restrictive in 2026, with tariffs reaching 50% and the calculation base expanding to full customs value.

• The tariffs on steel imports increased from 25% to 50% under Section 232 and came into effect on June 4, 2025.
• The bigger change arrived on April 6, 2026, when Section 232 duties began applying to the full customs value, rather than only the steel content. Core steel articles remained subject to a 50% tariff, while steel derivatives moved to a 25% full-value tariff.
• President Trump issued a proclamation on 1st June 2026. The proclamation established the temporary tariff framework which will be effective from June 8, 2026, through December 31, 2027.

The cost pressure is already visible. The producer price indexes for steel mill products increased by 20.7% from January 2025 to January 2026. It was the largest year-over-year increase since the supply-chain disruptions of early 2022.

For procurement teams, steel and aluminum price volatility in 2026 makes regional exposure increasingly important. Steel exposure now depends on both the product classification and the customs value, not simply the embedded metal value. So, commodity strategy for procurement built before April 2026 needs a full re-check. Also, contracts and sourcing budgets can now be planned against a known deadline of December 31, 2027, rather than an open-ended tariff.

Aluminum: The Two-Tier Market

There is no longer a single aluminum price in 2026. US buyers now pay roughly 70% more than the rest of the world for the same tonne of metal. There are three numbers required to understand the market dynamics.

• Global LME Benchmark: The LME benchmark is expected to average USD 3,400–3,800 per tonne as per major institutional forecasts for 2026.
• US Midwest Premium: Buyers from the United States pay a surcharge on top of the LME price for physical aluminum delivery inside the United States. The US Midwest premium hit a record of about $2,182 per tonne in early 2026. It crossed the $1 per pound mark for the first time.
• Real Cost to US Buyers: The rise in US Midwest premiums has increased the US “all-in” price to above USD 5,340 per tonne. US-based casters now pay 70% more than international competitors sourcing on the LME alone.

The cost impact is already visible downstream. The U.S. aluminum mill-shape prices rose 33% year-over-year in January 2026, and S&P Global reported U.S. aluminum imports fell 25% year-over-year in 2025.

The procurement implication is that aluminum should no longer be managed as a single global commodity price. The buyer’s actual cost now depends heavily on region, tariff exposure, and the premium. Recycled content is one lever inside that cost stack buyers can actually pull. See how CBAM adds to the aluminum cost picture for why a higher recycled share is now a financial decision, not just a sustainability one.

Rare Earths: A Different Kind of Volatile

Rare-earth volatility is structurally different from steel and aluminum. Its supply depends on concentrated processing capacity and export licenses instead of tariff rates.

NdPr prices show just how quickly things have shifted. NdPr alloy prices rose from $53/kg in January 2026 to around $126/kg by April 2026, representing a 138% year-to-date gain. Dysprosium also moved in the same direction. The price rose to $220.93/kg in April 2026, marking a 15.6% month-on-month increase.

The underlying vulnerability is concentration. No commercial-scale terbium production exists outside China, so buyers have no alternate source to shift toward if supply tightens further. Lynas produced its first terbium oxide in Malaysia in June 2025, marking a diversification milestone. So, western alternatives are emerging, but capacity remains limited.

For procurement, this changes the risk equation. A tariff can be repriced or removed, but qualifying alternative rare-earth supply requires new processing capacity, licenses, and years of investment. The concentration risk is exactly why the procurement-platform angle on this matters most in sectors like automotive, where rare-earth dependency runs deepest.

Temporary Noise or Structural Shift?

The answer depends on the commodity. Steel and aluminum face a policy-driven cost shock while rare earths face a structural supply risk that procurement cannot solve through tariff forecasting alone.

Steel and aluminum tariffs are a policy choice. The current 50%/25% structure is locked in only through December 31, 2027. That’s a fixed date set by proclamation, and a future proclamation can extend, reduce, or end it. The mechanism is political, which means it’s reversible or extendable. Rare earth volatility works differently. It is driven by mine concentration and export licensing.

This distinction should drive two different procurement responses to steel and aluminum price volatility in procurement, particularly through 2026. Steel and aluminum call for contract terms that price in tariff risk through 2027. Rare earths call for supplier diversification and buffer stock, because there’s no specific date when concentration resolves itself.

Treating all three commodities with one mitigation plan misses this. Thus, commodity strategy for procurement should treat the commodities differently: model policy scenarios for steel and aluminum but build supply resilience around rare earths. These are the kind of scenarios covered by JAGGAER’s tariff and geopolitical risk modeling.
