SHERIDAN, WYOMING - April 13, 2026 - Umicore operates one of the most formalized cobalt responsible sourcing programs in the materials sector, built on a four-step due diligence process that traces every lot of cobalt raw material to the mine level - a standard the company established as an industry first in 2004 when it became the first company globally to exclude artisanal and small-scale mining (ASM) cobalt entirely from its supply chain. With more than 65% of global annual cobalt supply originating from the Democratic Republic of Congo (DRC) and 15-20% of Congolese cobalt produced by ASM operations, Umicore's framework addresses persistent risks - child labor, human rights abuses, and unsafe working conditions - that remain structurally embedded in the cobalt supply chain.
Why cobalt sourcing is a systemic risk
Cobalt is a critical stabilizer in lithium-ion batteries powering consumer electronics and electric vehicles. As electrification scales globally to meet Paris Agreement targets, cobalt demand is forecast to rise substantially. The concentration of supply in the DRC - where ASM operations often involve hand-digging in tunnels, illegal intrusions onto large-scale mine concessions of up to 20 km², and exposure to cobalt dust - creates compounding compliance exposure for any company in the battery materials value chain.
The DRC's broader context of ethnic conflict, corruption, and poverty makes verification exceptionally difficult. Large-scale industrial mine (LSM) concession sites face illegal ASM intrusions that are inherently hard to police, and the volume of subcontractors and workers on LSM sites adds further traceability complexity. In 2020, approximately 75% of cobalt raw materials entering Umicore's supply chain originated from LSM activities in the DRC, with remaining volumes sourced from other countries or from recycling feed - the latter accounting for roughly 4.8% of total cobalt supply that year.
Four-step due diligence architecture
Umicore's Sustainable Procurement Framework for Cobalt structures supplier oversight into four recurring stages covering all existing and new suppliers. Supply chain traceability relies on a lot-receipts and labelling system that records all transactional and logistical documents as custody documentation, enabling mine-level origin tracking. Chemical fingerprinting - identifying specific impurity patterns - provides an additional verification layer beyond documentation alone.
Supplier research combines continuous off-site screening of company policies and external NGO and media reports with on-site and unannounced visits by locally based Umicore representatives and sustainability experts. Risk assessment maps each supplier against zero-tolerance criteria - including any form of child labor or inhuman treatment - and concern-level issues such as absent health and safety procedures. Evidence of a red flag terminates the supplier relationship. Umicore is also rolling out third-party audits covering Environment, Health, Safety and Social (EHS&S) standards for key suppliers as part of a continuous improvement cycle. The entire framework is validated annually by an independent third party - a practice Umicore established as a first in the industry.
Industry collaboration and blockchain traceability
Umicore co-created and actively participates in the Global Battery Alliance and its Battery Passport initiative, which formalizes responsible sourcing standards across the cobalt value chain. The company also participates in Re|Source, a blockchain-based platform designed to deliver mine-to-market traceability and accountability for cobalt, enabling collaboration across EV supply chain participants at scale.
On child labor specifically, Umicore was the first contributor to UNICEF's Fund for the Prevention of Child Labour in Mining Communities. Since 2011, the company has operated a school in Lubumbashi in collaboration with a local NGO, hosting more than 900 primary and secondary school children daily and serving thousands of children in the surrounding area. Cumulative investment in the school reached nearly $1 million by the time of reporting. Umicore also supports the NGO EIGHT in running unconditional cash transfers for a local Congolese community to reduce economic pressure driving child mining labor.
Business impact
Procurement leads and supply chain officers at battery manufacturers, automotive OEMs, and consumer electronics companies face escalating compliance obligations under the EU Battery Regulation and the EU Due Diligence Regulation. Supplier qualification processes must now incorporate mine-level traceability documentation, third-party audit records, and zero-tolerance child labor certification - capabilities that Umicore's framework already satisfies. Companies sourcing cobalt without equivalent controls risk regulatory penalties and exclusion from EU market access as these regulations move into enforcement phases.
Technology roadmap managers evaluating battery chemistry and raw material sourcing decisions in 2026 must account for the fact that cobalt traceability infrastructure - blockchain lot tracking, chemical fingerprinting, and annual third-party validation - is shifting from differentiator to baseline requirement. Vendor selection panels assessing cobalt refiners should now treat OECD Due Diligence Guidance alignment and independent certification as non-negotiable qualifiers, not optional assessments. The DRC's dominant role in global cobalt supply means no battery-sector sourcing strategy can treat ASM risk mitigation as peripheral - it is a central input into both regulatory compliance planning and reputational risk management.
