Since April 2025, Mainrich has handled composition review, documentation, and MOFCOM applications in-house.
Chemistry and documentation set the route. This is not a blanket ban, and Customs may inspect any shipment.
| Combined Dy + Tb ≤ 0.1% | Usually no MOFCOM license |
|---|---|
| Combined Dy + Tb above 0.1% | MOFCOM license typically required |
| License scope | One application per shipment |
| End-use verification | Required on the license path |
| Low-threshold shipment | Keep third-party composition report ready |
Exports continue through normal documents or per-shipment licensing.
Composition testing limits Customs holds and warehouse fees.
N, M, and H grades are the practical HREE-free path. SH, SHT, UH, UHT, EH, EHT, and AH classes usually need HREE-route review, composition testing, or licensing.
License steps apply above the threshold. The low-threshold path uses a third-party composition report and normal documents.
Sign a certificate naming the application and excluding military, nuclear, or aerospace use. Some countries require embassy authentication or local notarisation. Vague descriptions are often rejected.
File Dy and Tb composition, BHmax and Hcj reports, HS-coded datasheets, and application photos. Mainrich coordinates testing.
The EU, USA, and some other regions require buyer-side approvals. With no import license, a signed company-letterhead declaration is usually sufficient.
Review takes about 45 working days, with no rush service. Plan a 60-day buffer and consider smaller order batches.
Pre-screening, filing, formulation, and status remain with one team.
Check the dual-use threshold and End-Use Statement.
File, liaise with MOFCOM and Customs, and handle notarised translations.
Target the same thermal and coercivity requirements with less Dy and Tb.
Portal and email alerts cover submission, revision, and approval.
Parallel filing keeps finished goods out of bond.
The previous trading-company supplier filed only after production. Mainrich starts both tracks together.
Production, End-Use Certificate, and lab testing start.
MOFCOM submission while sintering is under way.
Review runs with grinding, coating, and quality control.
License approved, goods packed, shipment on schedule.

Confirm the likely route before locking production.
No. MOFCOM has no rush service. Complete documentation avoids preventable delays.
Automotive and robotics. EVs use 1 to 2 kg of HREE-doped magnets each, and industrial robots use 300 to 500 g per servo motor. Unprepared companies faced possible shortages within 90 days.
Yes. Mainrich handles formatting, translation, and submission. The buyer provides end-use information and a signature.
Mainrich has shipped low-HREE grades since mid-2025. They target the same thermal and coercivity requirements with less Dy and Tb, often below the threshold.
