I’ve been following China’s export control policies for over a decade, and the recent tightening on magnets—especially rare earth magnets—caught many supply chain managers off guard. Last year, I visited a magnet factory in Ningbo. The atmosphere was tense. Plant managers were scrambling to understand new license requirements while clients in Europe and the US were panicking about shipments stuck in customs. This article cuts through the noise. I’ll share what’s actually changing, which magnets are targeted, and the practical steps you need to take to avoid getting burned.
How China Controls Magnet Exports
China’s export control regime is based on two main pillars: the Export Control Law (effective 2020) and the updated Catalogue of Technologies and Products Subject to Export Prohibition or Restriction. Magnets fall under the “dual-use” category—items with both civilian and military applications. The Ministry of Commerce (MOFCOM) publishes a list of controlled items, and since 2023, certain neodymium-iron-boron (NdFeB) magnets and samarium-cobalt magnets require an export license.
Why This Happened
The official reason is national security and resource protection. China dominates rare earth mining and processing (about 80% of global supply), and magnets are used in everything from wind turbines to fighter jets. But I think there’s also a strategic play: by tightening controls, Beijing can leverage magnet supply in trade negotiations. A factory manager told me, “They’re not banning exports—they’re making them bureaucratic.” That bureaucracy is the real pain point.
What Magnets Are Affected
Not all magnets are controlled. Only those with specific technical parameters appear on the restricted list. Here’s a breakdown based on the latest catalogue (updated in 2024):
| Magnet Type | Key Parameter | License Required? |
|---|---|---|
| NdFeB sintered magnets | Br ≥ 1.5 T, Hcj ≥ 1600 kA/m | Yes |
| SmCo magnets | Any grade with coercivity > 2000 kA/m | Yes |
| Alnico magnets | None | No |
| Ferrite magnets | None | No |
| Bonded NdFeB magnets | If energy product > 50 MGOe | Yes |
Notice the thresholds. Many common industrial magnets (e.g., ferrite for loudspeakers) are free from controls. But high-performance NdFeB magnets—the kind used in EV motors and robotics—are tightly restricted. A common mistake I see is companies assuming all “rare earth magnets” are controlled. They’re not. Check the specs carefully.
Licensing Process and Red Tape
Getting an export license from MOFCOM is not a quick formality. Here’s the step-by-step based on what I’ve observed:
- Determine if your magnet falls under the controlled list. Use the technical parameters. If unsure, you can request a pre-verification from MOFCOM—though that takes 2-4 weeks.
- Prepare documents: End-user certificate, end-use statement, contract, and product specifications. The Chinese exporter submits these.
- Submit to local commerce bureau. They review and forward to MOFCOM.
- Wait for approval. MOFCOM has 30 working days to decide, but in practice it can stretch to 60 days. I’ve had clients wait 90 days for complex cases.
- Use the license. Valid for 6 months, single-use. You need a new license for each shipment.
What I’ve seen go wrong: Many exporters fail to specify the exact end-use. If the buyer says “industrial machinery,” that’s too vague. MOFCOM will reject it. You need to be precise: “permanent magnet motor for conveyor belt in food processing plant.” Even better, include a product photo or technical brochure.
Impact on Global Supply Chains
The controls have created a two-tier market. Companies with secure supply relationships (like long-term contracts with Chinese producers) still get magnets, but often at a 10-20% price premium due to licensing costs. Smaller buyers are squeezed out. I spoke with a German automotive Tier-1 supplier last month. They used to source NdFeB magnets from a medium-sized Chinese factory. Now that factory can’t get a license for their volume—they’re prioritizing their top 3 clients. The German company had to turn to a Japanese supplier, paying 30% more.
Another effect is inventory hoarding. I know of a drone manufacturer in Shenzhen that stockpiled six months of magnet inventory right after the controls were announced. That created a temporary shortage. Smart companies are now building dual sourcing strategies: keep a Chinese quota with a big producer while qualifying a secondary source in Vietnam or Thailand. But be warned: Chinese magnet producers are still the cheapest and highest quality.
How to Stay Compliant
Compliance isn’t just the exporter’s problem. Importers can also be penalized if they procure from unauthorized channels. Here’s my checklist for buyers:
- Verify the exporter’s license. Ask for a copy of the MOFCOM export license before payment. Cross-check the scope.
- Use proper incoterms. Prefer DDP (Delivered Duty Paid) so the seller handles export clearance. But even then, you want to see the license.
- Contract clause: Add a contingency clause that if the export license is denied, the contract is void without penalty.
- Consider bonded logistics. Some companies store magnets in bonded warehouses in Hong Kong. But note: Hong Kong has its own export controls, though less strict.
A piece of advice I rarely see online: don’t try to split shipments to avoid the license. Customs uses AI to flag unusual patterns. If you send 100kg of NdFeB in 10 boxes each labeled “samples,” they’ll catch it. I’ve seen fines of up to 5x the shipment value.
