U.S. imports of refractory ceramic bricks, blocks & tiles — other (not alumina/silica dominant) (HS 690290) totaled $3.3M in April 2026, traded with 23 countries.
Last updated: April 2026 dataRefractory constructional ceramics that do not derive their heat-resistance primarily from alumina or silica — including magnesia, chrome, zirconia, and specialty clay compositions — fall here, serving niche but demanding applications in non-ferrous smelting, glass tank linings, and waste incineration. Four 10-digit lines separate clay bricks (6902901010) from nonclay bricks (6902901020) and clay blocks/tiles (6902905010) from nonclay blocks/tiles (6902905020), making the clay-versus-nonclay distinction the primary classification axis. Germany and Japan are the leading suppliers to the US market under this heading, reflecting their established positions in advanced ceramic engineering. Chinese-origin goods may carry Section 301 exposure, a factor worth modeling when evaluating total landed cost.

The US tariff schedule uses the clay/nonclay distinction as the primary split: clay refractory bricks are classified under 6902901010 and nonclay refractory bricks under 6902901020, with a parallel division for non-brick shapes (6902905010 for clay, 6902905020 for nonclay). Articles based on magnesia, chromite, zirconia, or silicon carbide would generally fall in the nonclay lines, while traditional fireclay products fall in the clay lines.
Both countries have long-established advanced ceramics industries with proprietary compositions and quality certifications demanded by steel, glass, and chemical processing customers. Their products often command premium pricing justified by documented performance data — longer service life, tighter dimensional tolerances, and traceable chemistry — that lower-cost alternatives may not consistently match.
