I used to pore over Excel sheets late into the night, trying to connect trade lines and make sense of raw numbers. A little obsessive? Maybe. But when you’re chasing rare earths — those quiet but critical minerals behind EV motors, satellites, wind turbines — the devil is always in the data.
In 2025, China’s customs data offers us a window — sometimes a murky one — into how rare earth exports are shifting. Let’s walk that path together. My goal: you finish this and say, “Aha — I can use this.”
What the Data Tells Us (and What It Hides)
First, some context. China remains the world’s largest exporter of rare earths in many forms: raw oxides, compounds, magnets, and finished parts. But in 2025, export flows have become more volatile thanks to new licensing regimes, shifting policies, and rising geopolitical tension.
Here’s what the customs data shows:
- In May 2025, China exported about 5,864.6 metric tons of rare earths, a rise of ~23% from April. That made it one of the higher months in recent memory.
- Yet despite that jump, export volume in May was slightly lower year-on-year (–5.7%) for certain rare earth categories.
- Cumulatively, from January through July 2025, China’s rare earth exports hit ~38,563.6 tons — about 13% more than the same period in 2024.
- But that growth isn’t smooth. After peaking, exports slid in July, and in September 2025 they plunged ~31% compared to August, dropping to ~4,000 tons.
- Magnets, in particular, have seen dramatic swings. In April, magnet exports reportedly fell about 51%, as new export controls took effect.
- In terms of destination, downstream exports (like rare earth magnets) have strong demand in Germany, the U.S., South Korea, and Vietnam. In raw oxide or compound form, Japan and Vietnam take sizable share.
- In 2024, China shipped over 58,000 metric tons of rare earth magnets valued at nearly US$2.9 billion; about 18.8% went to Germany, 12.8% to the U.S., 10% to South Korea, and 8.1% to Vietnam.
- Among raw compounds/oxides, ~70% of export volume went to Japan, with Vietnam capturing around 7%.
- A more detailed 2023 breakdown shows exports of rare earth compounds from China: ~33,400,100 kg total, with top markets being Japan, the U.S., Korea, and Vietnam.
That’s the skeleton. The challenge: the data doesn’t always tell you why. License delays, policy signals, downstream demand shifts — those are hidden in the noise.
What the Swings Tell Us (and What They Warn)
Numbers don’t lie — but they also don’t tell you the whole story. What I see in the swings:
- Policy is power. The sudden drop in September signals more than market weakness: export licensing gatekeeping, restrictions, or administrative shifts can throttle flows rapidly.
- Midstream control matters most. When magnet and component exports slump harder than raw oxides, you know the choke points are in processing, not mines.
- Diversification in destinations is creeping. China is balancing its commitment to existing buyers with a desire to maintain leverage. Some markets might be deprioritized, others nurtured.
- Demand stress reveals vulnerabilities. Industries dependent on rare earth magnets — EV firms, wind OEMs — get exposed when one month’s supplies vanish.
- Seasonality and randomness mix. Some months are strong because buyers pull forward orders; others slump due to policy delays or permit cycles.
How You (Yes, You) Use This
Let’s move from analysis to action. Whether you’re sourcing, manufacturing, or strategizing, here’s your playbook.
1. Build an Export-Flow Dashboard
Don’t wait. Design a monthly view that tracks:
- Tons by export category (oxides, compounds, magnets)
- Top destination countries (and changes)
- Dollar values and implied $/kg
- Month-on-month and year-on-year percentage changes
Compare that to your internal forecasts and supplier reports. If customs data diverges from your inbounds, that’s a red flag.
2. Spot Forced Scarcity
If exports from China fall sharply — even if your orders haven’t changed — it may not be demand contraction. It could be administrative tightening: license backlogs, policy shifts, compliance audits. Treat sudden drops as “policy ambush zones,” not natural market moves.
3. Triangulate with Spot & Freight Data
Customs exports show what left China, not necessarily what arrives. Overlay your data with shipping manifests, local import data, and freight trends. If a container is stuck at port for weeks, that’s a signal.
4. Use Tiered Hedging Around Data Cycles
When customs data shows strength (say May’s 23% jump), lock in partial forward buys. When exports stall (September’s drop), pull forward material or buffer more. The goal: keep your line moving even when flows contract.
5. Push for Traceability in Supplier Contracts
Ask your sensors, magnet, or motor suppliers for monthly certified export data — or at least summaries aligning with customs categories. If their numbers diverge drastically from national exports, you have justification to renegotiate.
Walkthrough: What You Could’ve Seen (Hypothetical)
Imagine you’re a mid-tier EV motor maker in 2025. You rely on NdFeB magnets, which you source through a tier-1 magnet supplier in Korea, who in turn relies on Chinese-processed rare earth metals.
Your internal forecast called for gradually increasing magnet input from July to October. But customs data tells you:
- July exports slipped after a June peak
- September exports collapsed 31%
- April magnet exports halved
You flag to your procurement team: “We’re not safe.” You move to:
- Increase buffer stocks in Korea for Q4
- Interview alternate magnet suppliers in Europe
- Negotiate with your Korean supplier to lock in magnet pricing for Q1 next year
- Insert contract clauses to force notification if upstream Chinese export flow deviates 20%
Over time, that behavior helps you surf volatility instead of getting caught in it.
Things to Be Cautious About
- Re-exports and transshipments can distort the picture. Some flows labeled “China exports” might be partially or fully processed elsewhere and then shipped on.
- Data lags. Customs data often gets published weeks after the fact; always treat the most recent month as provisional.
- Changing HS classifications. Rare earths and magnets get re-coded, re-split. Watch for classification drift — that can hide or show volume shifts artificially.
- Policy transparency gaps. China may shift licensing quietly or selectively; the data might lag behind the change.
- Downstream demand shock. If a major buyer suddenly pauses orders, exports may plunge not due to supply constraints but collapsing downstream.

| Jan–Jul cumulative | ~38,563.6 tons | ~13% growth over same period 2024 |
| Sept vs Aug 2025 | –31% | Sharp drop likely policy/permit driven |
| Magnet exports in April | –51% | Midstream processing hit hard during new controls |
| 2024 magnet exports | ~58,142 tons, ~$2.9B | Germany, U.S., Korea, Vietnam top customers |
| Raw compound exports (2024) | ~6,000 tons | ~70% to Japan, ~7% to Vietnam |
The Bottom Line (Because You Skimmed Here)
- China’s customs export data in 2025 shows big swings — peaks, crashes, volatility.
- Those swings often reflect policy moves or administrative friction, not just demand.
- The hardest pinch points are midstream (magnets, compounds) — when those slow, entire supply chains wobble.
- You can use these data signals proactively: buffer, hedge, renegotiate, diversify.
- A good supply strategy treats customs data as a living instrument — one input, not a gospel.
