When companies assess critical mineral risk, they usually ask who mines a material, who processes it, who buys it, who stockpiles it, and who could cut off access to it.
Alain Richardt adds a useful sixth question in a recent article for ASPI’s The Strategist: What can replace it?


That question matters because supply and disruption move on different timelines. Developing a mine or refinery takes years. A trade restriction can change a manufacturer’s options much faster. Stockpiles can help bridge the gap, but they do not remove the dependency.


Finding a substitute does not mean swapping one material for another on a purchasing list. A candidate first has to meet the component’s requirements. Then the manufacturer has to prove it works in the actual product and production process without unacceptable changes to performance, reliability, or yield. Richardt describes these as two separate jobs: discovering the alternative and getting it ready for use.


The distinction is especially important for defense suppliers. Restrictions on covered materials expand on January 1, 2027, making the origin and processing of certain inputs relevant even when they sit deep inside an end product. A supplier cannot address that risk if it does not know which sub-tier parts contain the material. Nor can it rely on a promising substitute that has not been tested and qualified.


Where XTRIUM fits
At XTRIUM, we are building toward this sixth question.


Our focus is helping organizations bridge the gap between materials and their ideal applications: identifying potential substitutes, matching materials to functional requirements, and giving teams a clearer basis for resilient sourcing and product decisions.


That does not mean claiming every critical material has an easy replacement. Some do not. Substitution is not an argument against domestic extraction, allied processing, recycling, or strategic reserves.


It is an argument for treating material alternatives as a core pillar of resilience alongside them.


When an organization knows what a material does, where it is embedded, what could replace it, and what it will take to qualify that replacement, it has more than visibility. It has options.


In a world of increasingly concentrated supply chains, export controls, and tighter procurement requirements, options are what resilience looks like.
