U.S. imports of hydraulic cements (other) (HS 252390) totaled $5.5M in April 2026, traded with 8 countries.
Last updated: April 2026 dataHydraulic cements not elsewhere specified — including masonry cement, expansive cement, oil-well cement, and blended cements such as slag or pozzolan cements — are consolidated under tariff line 2523900000 when they do not meet the specific definitions of Portland, aluminous, or other named cement headings. Canada and Mexico are the primary US import sources, with Germany, France, and China also contributing. The breadth of this residual heading means classification disputes can arise when a blended or specialty cement product's composition is ambiguous, making detailed technical documentation essential.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Products commonly classified here include masonry cement, oil-well cement (API Class G or H), expansive cement, supersulfated cement, and blended cements (such as Portland-pozzolan or Portland-slag blends) that do not qualify as straight Portland cement under heading 2523.29. Importers should retain composition analysis and product specification sheets to support classification in this residual heading.
The classification turns on whether the product meets the compositional and performance definition of Portland cement under the HTS schedule notes. Blended cements with significant supplementary cementitious material additions may not qualify as Portland cement and should be classified under 2523900000. A binding ruling request to US Customs and Border Protection is advisable for novel or borderline products to avoid reclassification and penalty exposure.
