Concrete Bricks & Blocks

Because concrete masonry units are dense and relatively low in unit value, ocean freight and inland transportation costs often exceed the product cost itself. This makes nearby suppliers—particularly those in Canada or Mexico—far more competitive than distant origins, and importers typically evaluate landed cost rather than FOB price when comparing sources.

Compressive strength ratings, hollow versus solid construction, and whether units are load-bearing or non-load-bearing are the key specification distinctions. Customs classification can hinge on these characteristics, and importers should ensure technical data sheets accompany shipments to support the declared classification.
