HS Code for Mullite: 2025 Complete Guide
TL;DR: Mullite HS Code Essentials
Mullite HS code 2508.60 simplifies 2025 international trade for this key refractory mineral used in ceramics and bricks. Get accurate duties, compliance, and shipping tips in this guide.
What is the Exact HS Code for Mullite in 2025?
The primary HS code for mullite remains 2508.60 under Chapter 25 for 2025.
This covers aluminum silicate refractory materials. No major WCO revisions until 2027, but verify national updates like EU or US tariff schedules.
- HS 2508: Clays, andalusite, kyanite, silicates
- HS 2508.60: Specifically mullite
- Full code example: 2508.60.00 for raw mullite
Properties of Mullite and Why HS Code Matters
Mullite (3Al2O3·2SiO2) excels in high-heat uses, driving its HS code classification.
- Thermal stability up to 1800°C
- Low thermal expansion (4.5×10⁻⁶/°C)
- High creep resistance
- Chemical inertness
These traits demand precise HS code 2508.60 for correct duties in ceramics trade.
How to Find and Verify Mullite HS Code in 2025
Use official tools to confirm HS code for mullite amid 2025 national changes.
- Check WCO HS database
- Consult national customs portals (e.g., US ITC, EU TARIC)
- Review product composition certificates
- Test for mullite purity levels
- Consult HS classification experts
2025 updates include stricter silicate verifications in Asia-Pacific trade.
Mullite HS Code Breakdown: Chapter 25 Structure
HS Chapter 25 groups earths and stones; 2508 targets silicates like mullite.
| HS Code | Description | 2025 Notes |
| 2508 | Clays, silicates | No change |
| 2508.50 | Andalusite, kyanite | Related minerals |
| 2508.60 | Mullite | Refractory grade |
| 2508.70 | Chamotte | Fired clays |

Common Mistakes with Mullite HS Code Classification
Avoid misclassifying mullite under wrong HS codes to prevent 2025 penalties.
- Confusing with HS 6902 (refractory bricks)
- Ignoring purity thresholds (>70% mullite)
- Missing processed vs. raw distinctions
- Overlooking country-specific 2025 amendments
- Failing to update for composite materials
Result: Fines up to 100% of shipment value.
