Last updated: August 2026 dataNaturally occurring sand and gravel extracted for use in concrete, road base, fill, and general construction aggregate defines this category. Gradation, cleanliness, and particle shape — rounded versus angular — are the primary quality parameters that determine suitability for concrete versus base-course applications. Import activity is largely driven by regional supply shortages, particularly in coastal urban markets where local deposits are depleted or environmentally restricted, making marine bulk shipment the dominant import logistics mode.

While the US has extensive aggregate resources overall, local supply constraints — permitting restrictions, environmental regulations on dredging, and depletion of urban-area deposits — create regional shortages. Coastal cities in the Northeast and Southeast sometimes find it more economical to import sand and gravel by bulk vessel from nearby sources than to truck material from distant inland quarries.
Imported aggregates must meet the same ASTM or AASHTO specifications required by the purchasing project or jurisdiction — there is no separate federal import quality standard. Buyers typically require gradation analysis, cleanliness tests, and sometimes petrographic examination. Specification compliance is a contractual matter between buyer and supplier, verified through third-party testing before or upon delivery.
