U.S. imports of nonrefractory mortars & concretes (SITC 59898) totaled $7.1M in April 2026, traded with 18 countries.
Importers of Nonrefractory Mortars & Concretes paid $92K in duties in April 2026 — an effective duty rate of 13% on $703K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataReady-to-use or dry-blend nonrefractory mortars and concretes are bulk construction materials distinguished from refractory versions by their inability to withstand sustained high-temperature service. These products compete directly with domestically produced ready-mix and bagged concrete, making freight cost a dominant factor in import economics—bulk density and low unit value typically limit economical import distances. Classification as nonrefractory is confirmed by the absence of high-alumina, silicon carbide, or other heat-resistant binders that would redirect the product to a refractory heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Refractory mortars are formulated to withstand sustained temperatures typically above 1,000°C and contain high-alumina, silicon carbide, or similar heat-resistant binders. Nonrefractory mortars use ordinary Portland cement, lime, or gypsum binders and are intended for standard construction applications. The binder composition and any manufacturer's temperature-rating documentation are the primary classification evidence.
Nonrefractory mortars and concretes have high bulk density and relatively low value per unit weight, meaning ocean freight and inland transport costs can quickly exceed the product's commercial value over long distances. As a result, imports tend to be economically viable only when sourced from nearby trading partners or when a specialized formulation unavailable domestically justifies the logistics cost.
