Cerium Oxide Price Trend and Forecast 2026-2027

Cerium Oxide has held onto most of its 2025 gains through the first half of 2026, in sharp contrast to the metal it is derived from. Germany, the highest-cost region tracked here, saw the price ease just roughly 4.8% in Q2, from about USD 6.15/KG to close to USD 5.85/KG, nowhere near the double-digit drop seen in the cerium metal over the same stretch. The global average tells a similar story: down from around USD 5.28/KG in Q1 to near USD 5.06/KG in Q2, a decline of just under 4.2%. As the data shows, a global average of about USD 4.85 to 5.40/KG through H2 2026 looks reasonable, with the glass polishing demand providing a firmer floor here than in the underlying metal market.

The producers make Cerium Oxide (CeO2) by calcining the cerium carbonate, oxalate, or hydroxide pulled from the mixed rare earth concentrates, then milling the result to controlled particle sizes for whatever downstream application it is headed for. The grades range from the industrial abrasive-grade powder up to the high-purity material for the catalytic and electronic use. The precision glass and semiconductor wafer polishing is where the bulk of the demand sits, since the cerium oxide's chemical-mechanical polishing action simply outperforms the alternatives. The automotive catalytic converter washcoat formulations, the diesel particulate filter additives, and the agricultural fertilizer micronutrient blends make up the rest.

It is the feedstock costs for the cerium metal and carbonate that matter here, along with the calcination and milling energy costs, China's export licensing framework, and how the polishing and catalyst demand is trending downstream.

Cerium Oxide Price Forecast for 2026

Put together, Cerium Oxide looks set for a more resilient H2 2026 than the metal market underneath it. The precision polishing demand from the glass and semiconductor wafer manufacturers has held up even while the cerium metal corrected sharply on the co-product oversupply, mostly because the polishing-grade oxide has tighter particle-size and purity requirements that not every producer can reliably hit. The feedstock costs are easing in step with the metal market, but the processing and calcination costs put a firmer floor under the finished oxide than that alone would suggest. What the data points to is continued mild softening here, not a sharp repricing.

A surge in the semiconductor wafer demand that outpaces the qualified polishing-grade supply represents the main upside risk. The main downside risk runs the other way: if the cerium metal's oversupply-driven decline passes through more fully into the oxide processing margins, the prices would ease further below the forecast.

Cerium Oxide Prices in Germany

The German Cerium Oxide price averaged close to USD 5.85/KG in Q2 2026, down about 4.8% from near USD 6.15/KG in Q1. The cerium metal feedstock costs eased over the quarter, but the pass-through was only partial, since the steady precision optics polishing demand limited how far the finished-oxide price could fall.

Why did the price of Cerium Oxide change in Q2 2026 in Germany?

The cerium metal feedstock costs eased, but the calcination and milling costs kept the finished-oxide price largely intact regardless. The precision optics and semiconductor polishing demand did not let up. The gap between how much the metal moved and how much the oxide moved widened further, landing near USD 5.85/KG.

Cerium Oxide Prices in the United States

The United States Cerium Oxide price averaged about USD 5.58/KG in Q2 2026, down close to 4.3% from roughly USD 5.83/KG in Q1, as the firm wafer polishing demand from the domestic semiconductor fabrication offset most of the feedstock cost relief.

Why did the price of Cerium Oxide change in Q2 2026 in the United States?

The semiconductor wafer polishing demand stayed resilient even with the feedstock costs easing elsewhere. The automotive catalytic converter washcoat orders held roughly steady too. All told, the finished-oxide price only dropped modestly, to near USD 5.58/KG, despite the much sharper correction in the metal market underneath it.

Cerium Oxide Prices in Japan

The Japanese Cerium Oxide price averaged near USD 5.32/KG in Q2 2026, down roughly 4.0% from about USD 5.54/KG in Q1, as the electronics-grade polishing demand from the domestic wafer and display manufacturers limited how much of the feedstock relief actually passed through.

Why did the price of Cerium Oxide change in Q2 2026 in Japan?

The wafer and flat-panel display manufacturers kept the electronics-grade polishing demand firm through the quarter. The tight purity specifications meant the feedstock cost relief only passed through partially. The market held up relatively well, settling near USD 5.32/KG.

Cerium Oxide Prices in China

The Chinese Cerium Oxide price averaged close to USD 4.61/KG in Q2 2026, down about 5.7% from near USD 4.89/KG in Q1. The integrated producers here have direct access to cheaper cerium metal feedstock, which let the metal market correction pass through more fully than it did elsewhere.

Why did the price of Cerium Oxide change in Q2 2026 in China?

The integrated domestic producers passed through more of the cerium metal price decline simply because they have direct feedstock access. The export volumes rose in step with the metal shipments. It is the large integrated capacity that keeps China the cheapest oxide market tracked here, at around USD 4.61/KG.

The firm domestic and export polishing demand absorbed the steady output. The elevated feedstock costs sustained the margins ahead of the later co-product supply surge. The market firmed modestly to near USD 4.89/KG.

Quarterly Cerium Oxide Price Trends

As the data shows, six quarters of Cerium Oxide pricing consistently lag the sharper swings seen in the cerium metal, a pattern rooted in the tighter purity and particle-size specifications that separate the polishing-grade oxide from the bulk metal supply. The global average moved from about USD 4.68/KG in Q2 2025 to near USD 4.85/KG in Q3, close to USD 4.98/KG in Q4, and about USD 5.28/KG in Q1 2026, before easing to roughly USD 5.06/KG in Q2 as the feedstock relief began filtering through. Even after that pullback, the price still sits close to 8.1% above where it started in Q2 2025.

What was Cerium Oxide Price in 2025?

The steady polishing and catalyst demand carried Cerium Oxide through a full year of gains in 2025, largely insulated from the volatility that was quietly building underneath in the cerium metal market. The global average opened near USD 4.52/KG in Q1 and closed at about USD 4.98/KG by Q4, a full-year gain of close to 10.2%. The firm semiconductor wafer polishing demand deserves most of the credit, with the steady automotive catalyst washcoat orders and the cautious forward buying ahead of the anticipated Chinese licensing changes adding to the climb.

Cerium Oxide Prices in Germany in 2025

In Germany, it was the precision optics manufacturers who drove most of the 2025 demand story, lifting the price from about USD 5.35/KG in Q1 to near USD 6.05/KG by Q4, a gain of roughly 13.1%. The semiconductor-grade purity requirements kept the qualified supply tight throughout the year, a bottleneck few bulk producers could clear.

Cerium Oxide Prices in the United States in 2025

The United States market climbed from about USD 5.05/KG in Q1 2025 to close to USD 5.74/KG by Q4, a gain of about 13.7%, as the domestic semiconductor fabrication capacity expansion pulled the polishing-grade demand steadily higher through each quarter of the year. Each facility needed its own qualified suppliers first, adding a lag before demand shows in prices.

Cerium Oxide Prices in Japan in 2025

Japan's price path moved from roughly USD 4.80/KG in Q1 2025 to about USD 5.46/KG by Q4, a gain of close to 13.8%, supported by the consistent display and wafer manufacturer procurement and the generally stable import volumes from the Chinese suppliers. Preference for long-term qualification over spot buying means price moves show up gradually.

Cerium Oxide Prices in China in 2025

The Chinese price rose from roughly USD 4.05/KG in Q1 2025 to near USD 4.82/KG by Q4, a gain of about 19.0%, the steepest domestic move among the tracked markets as the export demand stayed strong and the integrated producers held back the incremental supply. A deliberate strategy, since integrated producers can afford to be selective about which contracts to fill.
