HS Code for Technical ceramics
View full HS code detailsTechnical ceramics are classified under HS code 6909.12. This classification falls within Chapter 69, which covers ceramic products. Heading 6909 is specifically for ceramic wares for laboratory, chemical, or other technical uses. Subheading 6909.12 is distinguished by the physical property of the material: it must have a hardness equivalent to 9 or more on the Mohs scale. This typically includes advanced ceramics made from alumina (aluminum oxide), zirconia, or silicon carbide. These materials are engineered for extreme environments where high wear resistance, thermal stability, and chemical inertness are required. Unlike decorative or structural ceramics, technical ceramics are defined by their industrial application and precise material composition. Classification under this code requires technical documentation or testing to verify the Mohs hardness, as this is the primary legal criterion for distinguishing it from other ceramic technical wares.
Products Included
- Alumina ceramic seals and valves
- Zirconia grinding media and components
- High-hardness ceramic laboratory crucibles
- Ceramic wear plates for industrial machinery
- Technical ceramic guides for textile machinery
Common Misclassification
The most common misclassification is HS code 6909.11, which covers ceramic wares for technical uses made of porcelain or china. If the material does not meet the Mohs hardness threshold of 9, it falls under 6909.11 or 6909.19. Another error involves HS code 8547.10, which is for insulating fittings for electrical machines. If a ceramic part is designed specifically and exclusively as an electrical insulator, it may be classified in Chapter 85 rather than Chapter 69.
FAQ
What is the HS code for technical ceramics?
The HS code for technical ceramics with a Mohs hardness of 9 or higher is 6909.12.
How is "hardness" verified for this HS code?
Hardness is measured on the Mohs scale; materials like alumina and zirconia typically meet the requirement of 9 or higher, whereas standard porcelain does not.
