Separate the industrial stages
MP Materials' January 2025 Independence announcement distinguishes metal production in Texas from magnet trials and upstream activity at Mountain Pass. It illustrates why a single company needs several records in a supply-chain review.
Start with the product your team needs. A buyer of finished magnets needs a different shortlist from a researcher assessing oxide separation. Record the producing site, product form and evidence date before considering the route domestic. Keep headquarters and sales offices out of the production count.

Build a route, not a list of US names
For each candidate, establish which upstream stages are disclosed and where they occur. A US customer, government award or American parent does not locate every conversion step in the country. Where a route is incomplete, specify the missing stage instead of assigning a broad domestic label.
Make the delivery horizon explicit. A project that could contribute in several years belongs in a future-supply view, not alongside qualified output for next quarter. Ask for current production, relevant specifications and allocation separately; an announcement about one does not answer the others.
Turn the map into a supplier question
In an illustrative sourcing review, two US sellers identify the same overseas metal maker. The useful finding is a shared upstream conversion dependency, not that either seller is unsuitable. Ask whether an alternative metal route has been qualified and what changing it would require. That is a concrete follow-up a country-only list would miss.
Three US supply claims to separate
| Claim | Evidence required |
|---|---|
| US company | Legal identity and ownership |
| US-made product | Named manufacturing site and process |
| US production route | Locations of relevant upstream conversions |
Your review checklist
- Define the required product stage.
- Separate operating evidence from expansion plans.
- Trace the metal and alloy steps.
- Confirm qualification and allocation with the supplier.

Does a US magnet plant imply US rare-earth feedstock?
Not by itself. Manufacturing and feedstock origin are separate findings that need matching evidence.
Should planned US facilities be excluded?
Keep them in a development comparison with explicit milestones and dates, rather than counting them as current alternatives.
