    USGS China chokehold warning: supply risk and project signals for US miners

    USGS China chokehold warning: supply risk and project signals for US miners

    First reported on MINING.com

    30 Second Briefing

    US mineral supply chains became more exposed in 2025, with the USGS reporting 100% import reliance for 16 of 90 tracked non-fuel commodities and more than 50% reliance for 54 minerals, up from 15 and 46 respectively in 2024. The US is totally dependent on imports of arsenic, natural graphite, manganese, niobium, tantalum, titanium sponge and 10 other minerals, with China supplying nearly half of arsenic and graphite, 55% of antimony and 70% of rare earths. In response, the Trump administration has proposed a $12 billion critical minerals stockpile and a JD Vance-led allied trade bloc, while industry warns US mine permitting still averages 29 years.

    Technical Brief

    • USGS 2026 Mineral Commodities Summary covers 90 non-fuel mineral commodities in its dependency analysis.
    • Sixteen fully import-dependent commodities include arsenic, asbestos, cesium, fluorspar, gallium, natural graphite and indium.
    • Additional fully import-reliant minerals are manganese, natural mica, niobium (columbium), rubidium, scandium, strontium, tantalum, titanium sponge and yttrium.
    • Only three of those 16 (asbestos, mica, strontium) are absent from the formal USGS critical minerals list.
    • A further 20 critical minerals show net import reliance above 50%, down from 28 the previous year.
    • China supplies about 55% of US antimony imports and roughly 70% of rare earth elements.
    • Canada is the leading import source for US aluminium, gallium, potash and zinc supply chains.
    • Chile and Mexico dominate US import sourcing for newly listed criticals copper and silver, respectively.
    • National Mining Association cites an average 29-year timeline from discovery to production for US mines, constraining rapid reshoring.

    Our Take

    The planned $12 billion US critical minerals stockpile flagged in the separate “Project Vault” policy piece in our coverage directly echoes the USGS concern here, signalling that materials like gallium, graphite and rare earths are being treated as strategic assets rather than just industrial inputs.

    In our database, USGS appears not only as a data provider in this report but also as a reference point in silver and copper market analysis, which suggests its critical minerals tracking is increasingly being used by investors as much as by policymakers.

    The 29‑year average mine development time in the US means that, for many of the 20–28 critical minerals with >50% net import reliance, near‑term supply security will likely depend more on stockpiling and offtake from allies such as Canada, Chile and Mexico than on new domestic greenfield projects.

    ICE critique of UK transport strategy: delivery risks for project teams

    The Institution of Civil Engineers has warned that the UK government’s new Better Connected integrated transport strategy lacks the clear, long-term objectives and investment pathways needed to steer major rail, road and mass transit schemes. ICE argues the document omits essential components such as defined modal priorities, a sequenced project pipeline and stable funding signals that asset owners and contractors require for planning multi‑decade programmes. The critique signals continued uncertainty for large schemes needing early geotechnical investigation, corridor safeguarding and staged capacity upgrades.

    US rare earth strategy shift: processing, price floors and risk for project teams

    US rare earth strategy is shifting from securing ore to controlling processing, with Aclara Resources’ Virginia Tech pilot and planned Louisiana separation plant illustrating a policy pivot towards domestic heavy rare earth separation for dysprosium and terbium used in EVs, wind and defence. Patricio Faúndez, economics leader at GEM Mining Consulting, notes Washington is now deploying price floors, equity stakes and long-term offtakes—tools long associated with China—to de-risk capital-intensive plants. The emerging model favours allied feedstock plus US-based processing, redistributing supply risk across jurisdictions rather than eliminating it.

    HBF calls for BNG reforms: planning and viability impacts for project teams

    Difficulties implementing mandatory Biodiversity Net Gain (BNG) are slowing housing projects, with a Home Builders Federation survey of 80 firms finding 84% still struggle with BNG and 80% reporting planning delays while local authorities review biodiversity assessments. Sixty per cent said BNG has deterred them from pursuing sites that would previously have been viable, citing policy uncertainty, inconsistent application of requirements and cumulative regulatory cost. Some capacity issues are easing, with reported shortages of in-house expertise down from 79% to 66% and adequate off-site biodiversity unit supply up from 31% to 47%.
