About HS Code 690912
This category encompasses highly specialized ceramic wares for laboratory, chemical, or technical uses that possess exceptional hardness, equivalent to 9 or more on the Mohs scale. These advanced ceramics, often made from materials like alumina, zirconia, or silicon carbide, are engineered for extreme wear resistance, high-temperature stability, and chemical inertness, making them indispensable in demanding industrial applications. Importers include aerospace, semiconductor, medical device, and advanced manufacturing industries. Exporters are typically highly specialized material science companies at the forefront of ceramic technology. The defining characteristic is their superior hardness, which dictates their use in critical, high-performance components.
Products Under This Code
Alumina grinding media, zirconia ceramic bearings, silicon carbide nozzles, boron carbide armor plates, high-purity alumina crucibles, ceramic pump components, wear-resistant ceramic liners
Real World Examples
Kyocera advanced ceramics, Saint-Gobain NorPro grinding media, Morgan Advanced Materials technical ceramics, CeramTec components
Common Misclassification
Often confused with 690919 (other technical ceramics) if the specific Mohs hardness isn't confirmed, or 8479 (machines with individual functions) if the ceramic component is integrated into a larger system.
Products Classified Under 6909.12
Trade Overview
Japan, Germany, and the USA are leading countries in both the production and import of these high-performance ceramic materials.
