Chinese Rare Earth Firms Refuse Shipments to the U.S., Supply Squeeze Persists
nashnova research
Several Chinese rare-earth suppliers have halted shipments to US buyers since early August, fearing punishment from Beijing for complying with American audit frameworks; the standoff is now on the agenda for Xi Jinping's September 24 US visit, but whether the summit breaks the supply logjam remains unclear.
Why did shipments suddenly stop?
The trigger: China sanctioned the Responsible Business Alliance (RBA) — an industry body that audits whether mineral sourcing meets compliance standards — in August.
Chinese firms worry that cooperating with the RBA-linked Responsible Minerals Initiative (RMI) audit framework — a system that traces ore from mine to factory — could be read by Beijing as "assisting US scrutiny" and invite penalties.
This means → firms face a double bind: comply with US audits and risk Beijing's punishment, or refuse and lose American orders.
In four separate cases before the RBA sanctions, Chinese suppliers had already declined to ship, citing fears that rare earths could be resold to sanctioned end-users.
Which materials are tightest?
Most rare-earth and magnet exports have partly recovered since China imposed controls in April 2025, but yttrium, indium phosphide, and tungsten remain near record-high prices.
In plain terms = these three materials feed defense, chip fabrication, and aerospace — the most sensitive fronts in the US-China contest.
Chinese customs data show US-bound yttrium exports have ticked up but still sit at roughly half of 2024 levels, while shipments to other countries surged.
Medical-device and energy firms are also caught in permit delays; some US companies have waited more than six months for mineral licenses.
Why did Beijing sanction US audit bodies?
Beijing framed the RBA sanctions as countermeasures, citing a string of restrictions the US FCC has imposed since last December.
The FCC restrictions cover Chinese electronic-testing labs, drones, consumer routers, subsea cables, advanced robotics, and power inverters.
This means → rare-earth export controls are not isolated — they are one move in a broader tit-for-tat over tech scrutiny and market access.
In bilateral talks, China countered that the FCC actions themselves violated the Busan agreement; each side accuses the other of non-compliance.
Are there signs of easing before the summit?
After two consecutive months of zero yttrium exports to the US, China shipped 27 tonnes in July — the second-highest single month since January 2025.
Several US firms have recently received multiple permits after prolonged waits; some expect approvals to accelerate around the summit.
Rhodium Group strategist Reva Goujon expects Beijing may modestly relax key-material controls near the summit to counter US accusations of non-compliance.
In plain terms = rare earths are being used as a bargaining chip — loosen the tap to signal goodwill, tighten it to apply pressure. The summit is the next window to watch.
