Rare Earth Events September 2026: Eight Key Conferences

• Nine rare earth and critical minerals events run across September 2026, spanning Seoul, Johannesburg, Tokyo, Shanghai, Yinchuan, Budapest, Marrakech, Brisbane and Bali.
• The International Critical Minerals and Metals Summit: Indonesia 2026 in Bali is this month’s headline event for REM readers — rare-earth-mining.com is a confirmed media partner, with a 15% reader discount available.
• Eight further events receive full coverage below; only AusIMM Brisbane already has a standalone REM guide and is linked out rather than re-covered here.
• The month opens with CLNB 2026 in Seoul on 3-4 September and closes with GIGA Africa in Marrakech on 29-30 September.
• Fastmarkets’ Budapest event and the T.I.C. General Assembly in Yinchuan both run into the following week’s cadence, so plan travel accordingly.

Rare earth events September 2026 form one of the busiest single months on the trading and conference calendar, with nine confirmed gatherings across four continents. The month covers battery raw materials, ferroalloys, automotive supply chains, tantalum and niobium, and broader critical minerals supply chains, with rare earth content threaded through most agendas even where it isn’t the headline topic.

International Critical Minerals and Metals Summit: Indonesia 2026

The International Critical Minerals and Metals Summit: Indonesia 2026 runs 27-30 September at the InterContinental Bali Resort, co-located with CT Asia. This is the standout event of the month for REM readers: rare-earth-mining.com is a confirmed media partner, and readers attending can use discount code CRITICALMINERALS15 for 15% off registration. The summit covers nickel, tin and battery materials alongside a dedicated rare earth roundtable, reflecting Indonesia’s growing position in the broader critical minerals conversation even though the country’s own rare earth resource base remains earlier-stage than its nickel and tin sectors.

CLNB 2026 — Asia Battery Material Cooperation Forum

CLNB 2026 runs 3-4 September in Seoul, South Korea, organised by Shanghai Metals Market (SMM). The forum draws confirmed participants including Ecopro, Hyundai Steel and Umicore, with sessions on material technology, market trends, supply chain security and cross-border cooperation. Full programme details are available at SMM’s event page.

Battery materials and rare earth supply chains are not the same market, but they increasingly share the same buyers, the same geopolitical pressure points, and in many cases the same processors. EV motors built with NdFeB permanent magnets sit downstream of the same automotive OEMs sourcing lithium and nickel for cells, which makes SMM’s cross-border cooperation agenda relevant reading for rare earth market participants tracking how Asian supply chain diversification strategies are evolving outside China.

Critical Materials Conference: Ferroalloys 2026

Project Blue’s Critical Materials Conference: Ferroalloys 2026 takes place 8-9 September in Johannesburg, South Africa. The 2026 edition follows a 2025 conference that drew over 150 attendees, and covers supply, demand and pricing trends across manganese, chrome, vanadium and ferrosilicon. Registration details are at Project Blue’s conference page.

Ferroalloys sit outside REM’s core coverage, but the Johannesburg conference draws the same minor metals trading community that shows up at MMTA and T.I.C. events. MMTA members receive a 10% discount to attend, reflecting the overlap between ferroalloy traders and the broader minor metals network that also handles rare earth intermediates and byproducts.

Critical Minerals Japan Conference & Exhibition

Critical Minerals Japan runs 9-10 September at Akasaka Intercity Air in Tokyo, bringing together over 200 senior international executives across mining, government, private equity and downstream manufacturing. The programme addresses Japan’s economic security dependence on critical minerals across semiconductors, batteries, EVs and defence applications. Full details are at the Critical Minerals Japan event site.

Japan’s rare earth position gives this event particular weight. The country still relied on China for over 60% of its rare earth supply as of 2024, down from roughly 90% in 2010, a reduction achieved mainly through diversification toward Malaysia and Vietnam. That dependency, and Tokyo’s continued push toward supply autonomy including investment in reserves around Minami-Torishima Island, is the backdrop against which this conference’s government and industry sessions will run.

ASCC 2026 — SMM 8th Automotive Supply Chain Conference

SMM’s 8th Automotive Supply Chain Conference & Industry Collaboration Forum runs 10-11 September in Shanghai. The agenda examines material trends and supply chain practices for passenger vehicle production, with particular emphasis on lightweight structures, recycled aluminum, aluminum die casting and profiles, and steel and magnesium alloys, against a backdrop of NEV penetration exceeding 50% in China and mounting pressure from the EU’s carbon tariff regime.

Like CLNB, ASCC’s core subject matter — aluminum and steel lightweighting — sits outside rare earth pricing directly, but the conference’s automotive OEM audience is the same buyer base driving NdFeB magnet demand for EV traction motors. Supply chain restructuring conversations happening here, particularly around China’s shift from scale advantage to technology and supply chain leadership, run parallel to the same dynamics shaping magnet rare earth procurement.

T.I.C. 67th General Assembly and Conference

The Tantalum-Niobium International Study Center holds its 67th General Assembly and Conference 13-16 September at the JW Marriott in Yinchuan, China. The T.I.C. represents around 90 member companies from over 30 countries across the tantalum and niobium supply chain, and the annual assembly combines the AGM with business and technical presentations. Programme information is published at tanb.org.

Tantalum and niobium are not rare earth elements, but their supply chains run through the same specialty metals trading houses and often the same ore bodies as rare earth byproduct streams, including monazite and pyrochlore deposits. The 2026 assembly marks the second consecutive year the event has moved into China, following 2024’s 50th anniversary gathering in Tokyo, a shift worth watching for anyone tracking where minor metals trading influence is concentrating.

Fastmarkets European Battery Raw Materials 2026

Fastmarkets moves its European Battery Raw Materials conference to Budapest for 15-17 September 2026, reflecting Hungary’s position as Europe’s largest battery cell manufacturing base. The agenda covers lithium, nickel, cobalt, graphite, recycling and project finance, including a CATL Debrecen gigafactory site visit. Registration is through Fastmarkets’ event platform.

The event’s own materials cite REsourceEU as moving €3 billion from policy commitment into live projects, part of the broader European push to build midstream processing capacity that current gigafactory buildout has exposed as a gap. That midstream investment conversation runs parallel to Europe’s separate rare earth magnet and permanent magnet recycling ambitions, making the Budapest agenda a useful proxy for how EU industrial policy money is actually being deployed this year.

GIGA Africa 2026

Benchmark Mineral Intelligence’s GIGA Africa returns to the Four Seasons Resort in Marrakech, Morocco, for 29-30 September, its second edition following the inaugural 2025 event. The conference focuses on Africa’s expanding role in critical mineral production and the battery supply chain, with a new investor-matching programme, Benchmark Connect, added for 2026. Full agenda details are at Benchmark’s event page. REM’s Morocco rare earth guide covers the country’s broader deposit and processing landscape.

Morocco’s OCP, the state phosphate group with confirmed speaker representation at the 2026 event, is relevant to rare earth watchers beyond its core fertiliser business — phosphate rock processing generates rare earth-bearing byproduct streams that several producers globally are now working to recover commercially. GIGA Africa’s government and industry mix, spanning Zimbabwe’s Ministry of Mines to Volkswagen Group Africa, gives a useful read on how African critical minerals policy is being positioned to investors this year.

Also on the calendar

One further September event already has standalone REM coverage. The AusIMM Critical Minerals Conference 2026 runs 21-23 September at the Brisbane Convention and Exhibition Centre, with a full three-day technical programme on rare earth project development and processing.
