HS Code 6902.20 – Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods; containing by weight more than 50% of alumina (Al2o3), of silica (SiO2) or of a mixture or compound of these
HS code 6902.20 is the 6-digit subheading for refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, containing by weight more than 50% of alumina (Al2o3), of silica (SiO2) or of a mixture or compound of these. It is used for high-alumina bricks, silica bricks, fireclay bricks, mullite bricks and corundum bricks.
What HS 6902.20 covers
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.

Codes often confused with 6902.20
Common mistake. 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.
Top exporters and importers of HS code 690220, 2025
In 2025, the largest exporter of HS code 690220 in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was the United States, with 7.9% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
