About HS Code 690220

This HS code covers refractory ceramic bricks, blocks, tiles, and similar constructional goods that contain, by weight, more than 50% of alumina (Al2O3), silica (SiO2), or a mixture/compound of these. These 'acidic' or 'neutral' refractories are fundamental to a vast array of high-temperature industrial processes, including those in the glass, ceramics, petrochemical, and foundry sectors. Their properties, such as high refractoriness, good thermal shock resistance, and chemical stability, make them crucial for lining furnaces, kilns, and other thermal processing units. Importers are diverse industrial economies requiring durable and reliable high-temperature linings. Exporters are countries with access to bauxite (for alumina) or high-purity silica resources, coupled with advanced ceramic manufacturing capabilities. The specific ratio of alumina to silica dictates their performance characteristics and suitability for different applications.

Products Under This Code

High-alumina bricks, Silica bricks, Fireclay bricks, Mullite bricks, Corundum bricks, Zirconia-alumina-silica bricks, Insulating firebricks (alumina-silica based)

Real World Examples

Saint-Gobain high-alumina refractories, HarbisonWalker International fireclay bricks, Morgan Advanced Materials mullite products, Shinagawa Refractories silica bricks

Common Misclassification

Often confused with 690100 if the silica content is high but not derived from siliceous fossil meals, or with 690290 if the composition is complex but still primarily alumina/silica based.

Products Classified Under 6902.20

Trade Overview

China, Japan, and the USA are major producers and traders of these refractories, with global industrial demand driving imports.
