Last updated: August 2026 dataHigh-alumina and silica-dominant refractory shapes are critical consumables in steel, glass, cement, and petrochemical furnaces, where their thermal stability under extreme temperatures determines campaign life. The US schedule breaks this heading into four 10-digit lines distinguishing alumina bricks (6902201010), other silica/alumina bricks (6902201020), alumina blocks and tiles (6902205010), and other silica/alumina blocks and tiles (6902205020). India leads US supply under this heading, followed by Mexico and Germany, reflecting both low-cost production capacity and proximity advantages. Importers should note that Chinese-origin refractory products may be subject to Section 301 tariffs, making supplier diversification a live cost-management issue.

The schedule separates alumina bricks (6902201010) from other refractory bricks containing over 50% silica or alumina but not classified as alumina bricks (6902201020). A parallel split applies to non-brick shapes: alumina blocks and tiles fall under 6902205010, while other silica/alumina blocks and tiles are classified under 6902205020. The key classification driver is whether alumina is the dominant constituent and whether the article is a brick versus another constructional shape.
Yes. Refractory ceramic goods originating in China may be subject to Section 301 tariffs in addition to the standard column 1 duty rate. Importers sourcing from China should verify the current Section 301 list status for the applicable 10-digit HTS line before finalizing landed-cost calculations, as rates and product coverage have been subject to revision.
