Last updated: April 2026 dataReady-to-use and dry-mix nonrefractory mortars and concretes — formulations that do not withstand high-temperature service — are traded under this heading, covering products from standard masonry mortars to specialty repair concretes. The US schedule distinguishes wet formulations (3824500010) from all other forms (3824500050), a split that reflects differences in packaging, shelf life, and transport logistics. Canada and Mexico are the dominant suppliers, driven by cross-border construction project demand and the economics of shipping heavy, low-value-density materials over short distances.

Wet mortars and concretes (3824500010) are pre-mixed with water and ready for immediate application, while the NESOI line (3824500050) covers dry-blend powders, bagged mixes, and other non-wet forms. The physical state at the time of importation — not the intended end use — determines which 10-digit line applies.
Nonrefractory mortars and concretes are heavy and relatively low in value per unit weight, making long-haul ocean freight economically impractical for most grades. Cross-border truck shipments from Canada and Mexico keep landed costs competitive, so supply geography for this heading is heavily shaped by transport economics rather than raw material availability.
