Clay & Refractory Building Materials

Antidumping duty orders have been imposed on certain clay products, including facing bricks, from specific countries in past proceedings. Importers should check the International Trade Administration's ADD/CVD database for current orders covering their specific product and country of origin before sourcing, as scope can be narrow and product-specific.

ASTM C62 (building brick), C216 (facing brick), C652 (hollow brick), and C1167 (clay roof tile) are the primary standards specifying grade, durability, and dimensional tolerances. Importers supplying the US construction market should obtain third-party test reports from accredited laboratories confirming compliance with the applicable ASTM grade before shipment.
