The context
Country, corporate and technology concentration are separate dimensions. A company’s headquarters does not identify every mine or refinery it operates, and mine output does not measure available high-purity material. A domestic resource deposit may still depend on foreign separation equipment, processing reagents, energy or customer qualification.
Critical-mineral classifications provide a useful policy reference but not a universal closed list of strategic resources. Structural observations retain their year and processing stage. Demand scenarios remain projections; an announced investment, contractual award or prospective reserve does not become current physical supply.
What we track
Definitions and interpretation below describe our coverage. They are not live readings or mechanical buy/sell instructions.
Stage-specific supply concentration
Country and company shares of mining, refining, separation, fabrication or qualified equipment output on a consistent dated basis.
How to read it: Concentration can migrate downstream even when mineral extraction is dispersed. Company roles and operating locations must be verified before translating a country-level statistic into a firm’s production exposure.
Source & methodology ↗Import dependence and stockpile coverage
Reported import reliance, inventories and consumption under matched product and geographic definitions.
How to read it: Strategic stockpiles, exchange warehouses and private customer inventories have different accessibility. Missing commercial stocks cannot be treated as zero, and reserves in the ground do not measure emergency inventory.
Source & methodology ↗Substitution and qualification time
Evidence of alternative materials, suppliers, recycling pathways and the technical or regulatory steps needed for adoption.
How to read it: A material may be substitutable in one use but indispensable in another. Redesign, certification, lower performance and additional inputs can make a nominal alternative commercially unavailable within the relevant disruption window.
Source & methodology ↗Qualified capacity and offtake
Operating versus planned output, commissioning and qualification milestones, outage status and disclosed offtake obligations.
How to read it: Long-term contracts can support project finance while reducing uncommitted supply. Awarded funding and nameplate capacity should not be counted as delivered output; contract terms and counterparties determine practical availability.
Source & methodology ↗Trade and logistical access
Dated customs flows, product classifications, port movements and policy events associated with the resource.
How to read it: Aggregate trade codes can combine grades and processing stages. Shipment delays, rerouting and export licenses affect delivery, but estimated port flows cannot establish a precise inventory of semiconductor-grade or nuclear-qualified material.
Source & methodology ↗Comparable prices and input economics
Dated quotations with product form, purity, location, unit, currency, tax and delivery basis retained.
How to read it: Resource costs should be compared within a defined series. Uranium oxide, lithium carbonate and vanadium pentoxide are not elemental-metal prices; equipment and fuel-cycle services often lack transparent spot markets.
Source & methodology ↗How we cover it
The eight themes are Advanced Compute & Microelectronics; Rare Earth Elements (REEs); Technology Minerals & Substrates; Energy Transition Minerals; Essential Semiconductor Inputs; Nuclear Fuel & Energy; Aerospace Metals & PGMs; and Agricultural & Fertilizer Inputs.
Rare-earth coverage includes scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. Promethium is treated as a specialized synthetic supply case, not a conventional mined commercial commodity.
The broader chain includes accelerators, chip equipment and materials, batteries, grid equipment, industrial gases, fertilizer inputs and nuclear conversion/enrichment/fabrication. Shared metal and currency series retain one consistent source definition instead of generating contradictory parallel quotes.
What the numbers can miss
A single supplier’s product page does not establish current lead time, capacity or stock availability. Company examples describe roles, not an independently verified production league table.
Licensing, security-sensitive information, by-product economics and sparse trading leave genuine gaps. Nominal prices across unlike units cannot support a universal strategic-value ranking.
