Gallium Price Index: Assessment Methodology, Benchmarks, and Market Structure

Gallium Price Index: How Price Discovery Works

Gallium prices are set by bilateral negotiation between sellers and buyers, with no exchange or clearinghouse. The term "gallium price index" as used in commercial contexts refers to the assessed price published by a named price reporting agency, most commonly Argus Media. When a supply contract states "price = Argus gallium 4N ex-works China, quarterly average, plus agreed premium," the Argus assessment is functioning as an index. Argus and Fastmarkets assess two grades - 4N (99.99%) and 6N (99.9999%) - at multiple geographic points, giving buyers and sellers four to six distinct price references depending on their delivery location and purity requirement.

Asian Metal publishes daily free-access price data for FOB China and EXW China gallium, which serves as a baseline reference for market participants without PRA subscriptions. The USGS publishes annual average gallium prices in its Mineral Commodity Summaries, useful for historical analysis but updated only once per year. See gallium price history for the full historical price dataset.

Which Organizations Publish Gallium Price Assessments and How Often?

Four price reporting agencies cover gallium actively: Argus Media (twice weekly), Fastmarkets (weekly), Asian Metal (daily), and Shanghai Metals Market (daily). Argus is the most commonly cited in Western supply contracts. Asian Metal and SMM are the standard references for China domestic market participants. USGS publishes annual averages free of charge.

Argus Media is the most widely referenced benchmark in European and US supply contracts for gallium, based on its twice-weekly assessment frequency, dual-grade (4N and 6N) coverage, and multi-geography publication. Argus's gallium coverage sits within its Minor and Specialty Metals platform, alongside indium, germanium, and bismuth. Fastmarkets covers the Rotterdam in-warehouse basis most closely tracked by European traders and distributors.

No agency publishes a 7N, 8N, or 9N gallium price. Those grades trade on custom negotiated contracts between refiners and end-users with no public price disclosure. Argus's twice-weekly 6N assessment is the highest purity grade with any regular published benchmark. See gallium purity grades for the 4N-to-9N specification system and the price premium structure by grade.

How Do Argus Media and Fastmarkets Assess Gallium Prices?

Argus assesses gallium twice weekly using a methodology based on verified market inputs: transaction reports from buyers and sellers, bids and offers from active traders, and market intelligence from industry contacts. Fastmarkets uses a weekly assessment cycle with similar survey-based methodology. Both agencies publish a single assessed price point (or range) rather than a volume-weighted average, because actual transaction volume in gallium is too low for statistical averaging.

The assessment process for a minor metal like gallium differs from base metal assessments in three ways. First, the number of market participants is small: perhaps 10-20 significant gallium trading entities globally, compared to thousands in copper or aluminum. Second, transactions are infrequent - the spot market represents an estimated less than 5% of gallium volume, with the remainder in bilateral contracts rarely disclosed. Third, the export control environment since August 2023 has reduced the number of observable arm's-length cross-border transactions, which makes assessment harder and increases reliance on bid/offer evidence rather than closed trades.

Both Argus and Fastmarkets publish methodology documents describing how they collect data, resolve conflicts between data points, and set the final assessed value. The Minor Metals Trade Association (MMTA) is the trade body representing minor metals producers, traders, and consumers in Western markets. The MMTA does not publish prices but maintains a directory of member companies and provides a forum for market participants. It does not certify or endorse any PRA's gallium assessment as an industry standard, though Argus assessments are the de facto choice in contracts among MMTA-member trading companies.

What Geographic Price Points Does Gallium Trade At?

Four standard geographic basis points apply to gallium: EXW (ex-works) China in CNY/kg, FOB (free on board) China in USD/kg, CIF Rotterdam in USD/kg, and in-warehouse Rotterdam in USD/kg. Each basis reflects a different point in the logistics chain. The spread between EXW China and in-whs Rotterdam widened from approximately $50-100/kg before August 2023 to over $1,000/kg in 2024-2025 as export controls made Chinese gallium physically unavailable to Western buyers at the domestic price.

Before August 2023, the spread between EXW China and CIF Rotterdam was primarily logistical: freight plus handling, typically $50-100/kg. Since August 2023, the spread has expanded dramatically because most gallium physically present in Western warehouses was purchased before export controls took effect, and replacement inventory requires export licenses that China grants slowly or not at all for US buyers. As of early 2025, Fastmarkets assessed Rotterdam at $1,450-1,500/kg versus China domestic at 2,000-2,070 CNY/kg (~$274-283/kg), a spread of approximately $1,170-1,220/kg attributable to the export control premium.

Buyers sourcing gallium for Western fabrication need to specify which geographic basis they are referencing when comparing price quotes. A China FOB offer of $400/kg and a Rotterdam in-warehouse offer of $1,450/kg are not necessarily divergent - they reflect the same underlying material at different supply chain stages, plus the current export control scarcity premium.

What Gallium Grades Do Standard Price Assessments Cover?

Argus Media assesses 4N (99.99%) and 6N (99.9999%) gallium. Fastmarkets assesses 4N only. Asian Metal and SMM assess 4N. No agency publishes a standard 7N, 8N, or 9N price. The 6N assessment from Argus commands a premium of approximately 15-25% above the 4N price in published assessments, though actual 6N contract prices negotiated between wafer producers and refiners are not publicly disclosed.

The Argus 6N assessment represents the highest purity grade with any regular published benchmark in the gallium market. However, the Argus 6N assessment reflects indicative market levels rather than frequent observed transactions - 6N gallium changes hands less frequently than 4N, and most volume moves under long-term negotiated contracts. The practical price for 6N gallium in a specific transaction may deviate from the Argus assessed value based on volume, delivery timing, and the specific impurity profile required. See gallium purity grades for element-by-element impurity specifications at each grade.

How Are Gallium Price Indices Used in Supply Contracts?

Long-term gallium supply contracts (1-3 year terms) use Argus or Fastmarkets assessed prices as the pricing formula base. A standard structure is: price per kilogram = Argus gallium 4N ex-works China quarterly average + negotiated premium or discount, adjusted each quarter. The Argus or Fastmarkets assessment functions as the floating index; the premium or discount reflects volume, quality, and relationship factors negotiated between buyer and seller.

Compound semiconductor manufacturers - GaAs wafer producers (AXT, Freiberger, Sumitomo Electric), GaN epitaxy providers (Wolfspeed, IQE), and large integrated chip makers (Infineon, Qorvo) - structure gallium procurement in two tiers. The first tier is a long-term contract covering 70-80% of annual volume at index-linked pricing with quarterly resets. The second tier is spot purchasing for the remaining 20-30% to cover demand variability, sourced from traders at a premium to the published index.

Force majeure clauses in post-2023 contracts explicitly reference China export control events as a trigger. Before August 2023, Chinese export restrictions on gallium were not standard contract risk language. After the August 2023 licensing implementation virtually halted gallium exports - from 6,876 kg in July 2023 to 227 kg by October 2023 - buyers began requiring explicit coverage for export restriction events in new contract terms.

Price-linked contracts using a PRA assessment as the formula base give both parties transparency: the index is independently calculated and publicly verifiable (with a subscription). Fixed-price contracts transfer price risk entirely to one party. Given the 5x price move between 2022 and 2025, fixed-price contracts for multi-year terms have become uncommon. Most current agreements use the indexed structure with quarterly resets.

Why Is Gallium Not Traded on a Commodity Exchange?

Gallium's market structure - one dominant producer country (China at ~99%), low annual trading volume (~750 metric tonnes globally), bilateral rather than standardized transactions, and no fungible contract specification - makes it unsuitable for exchange trading. The LME requires deep liquidity, multiple competing suppliers, and a standardized contract grade. Gallium meets none of these criteria. The total annual gallium market value is approximately $50-100 million at current prices - smaller than a single day's copper trading volume on the LME.

Exchange-traded commodity markets require three conditions gallium currently lacks:

• Multiple competing suppliers that can deliver against a standard contract. Gallium at 99% Chinese production concentration cannot support a multi-supplier exchange contract.
• Sufficient transaction frequency to generate a credible settlement price. Gallium spot transactions represent less than 5% of total volume; the remainder is in bilateral contracts whose prices are not disclosed.
• A standard product specification that buyers and sellers treat as interchangeable. Gallium at 4N purity from different Chinese refiners may have different impurity profiles that matter to GaAs wafer producers, making strict fungibility difficult.

The absence of exchange trading has two consequences for buyers. First, there is no publicly visible price discovery in real time - published assessments lag the market by days and reflect surveyed opinions rather than matched trades. Second, there is no hedging mechanism: a chip manufacturer with a 12-month gallium requirement cannot lock in a price through futures contracts the way an aluminum consumer can on the LME. The only hedging tool available is a fixed-price supply contract, which transfers risk to the counterparty rather than to a liquid futures market.

What Drove Gallium Price Volatility From 2023 to 2025?

China's July 2023 export licensing announcement triggered a 27% price increase within weeks, rising from ~$240/kg to ~$326/kg ex-works China by October 2023. Monthly exports collapsed from 6,876 kg in July 2023 to 227 kg in October 2023. The December 2024 US export ban widened the China domestic-to-Rotterdam price spread further. By early 2025, Rotterdam in-warehouse prices reached $1,450-1,500/kg while China domestic prices remained at approximately $274-283/kg equivalent.

Gallium and germanium prices have moved together since August 2023 because China's export controls applied to both metals simultaneously. Both are byproduct metals with ~99% Chinese primary production. Both serve as inputs to compound semiconductors and advanced optics at the center of US-China technology competition. The synchronized control of both metals is a deliberate policy instrument, not a coincidence.

The byproduct nature of gallium production creates a structural supply rigidity that amplifies price volatility: gallium output tracks alumina refining, not gallium demand or price. A 5x price increase does not directly incentivize new gallium supply because gallium producers are aluminum companies whose investment decisions respond to aluminum prices. Demand-driven or policy-driven price shocks are absorbed through price rather than supply response.

What Free Public Sources Track Gallium Prices?

USGS Mineral Commodity Summaries provide annual average gallium prices free of charge as a public PDF. Asian Metal publishes baseline FOB China daily prices with free access to current data. Shanghai Metals Market provides China domestic daily prices at free access. Fastmarkets and Argus are paywalled; Fastmarkets publishes free article-length market commentary alongside its paywalled price data. All detailed historical time series beyond 3-6 months are paywalled across all commercial providers.

For buyers without PRA subscriptions, the Asian Metal FOB China price provides a daily directional reference for the China export price, though it should be adjusted for freight, insurance, applicable export license premium, and the grade premium for 6N versus 4N. The USGS annual average is the most authoritative public figure for year-over-year comparison but cannot be used for current contract pricing.
