AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes, gray Portland cement and clinker have historically been the subject of US antidumping duty orders against specific countries. Importers should check the current scope of any active orders with the US Department of Commerce and US International Trade Commission before sourcing, as duty liability can be substantial and retroactive.
ASTM performance types do not create separate HTS subheadings — all non-white Portland cement types classify under 2523290000 regardless of ASTM designation. The type distinction matters for end-use specification and quality documentation but is not a classification variable at the tariff schedule level.
