HS Code 6902 — Refractory Bricks and Structural Ceramics
This code covers heat-resistant ceramic materials designed to withstand temperatures above 1,500 degrees Celsius. These are primarily used to line furnaces, kilns, and reactors in heavy industries like steelmaking and glass manufacturing.
What's included
- Magnesite bricks
- Alumina-silica refractory blocks
- Fireclay bricks
- Chrome-magnesite tiles
What's excluded
- Siliceous fossil meal bricks → use
6901(Made from lightweight earth like kieselguhr which is classified separately.)
Common examples
- High-alumina furnace lining bricks
- Magnesia-carbon refractory blocks for steel ladles
- Silicon carbide furnace tiles
- Refractory checker bricks for regenerators
Frequently asked questions
What determines the sub-classification of 6902?
It is based on the chemical content, specifically the percentage by weight of alumina, silica, or magnesium oxide.
Trade & shipping notes
- Typical duty range: 0% - 6.5%
- Documentation: Mill certificates specifying chemical composition (Al2O3 and SiO2 content) are essential for correct sub-classification.
- Typical shipping mode: FCL
- Top exporters: China, Germany, India
- Top importers: United States, South Korea, Japan
