Last updated: August 2026 dataPebbles, gravel, and crushed or broken stone used as concrete aggregates, road ballast, or railway track ballast are among the highest-volume, lowest-value mineral imports by weight, making freight economics and port proximity the dominant sourcing factors. The US schedule covers pebbles and gravel (2517100015), limestone other than pebbles and gravel (2517100020), and other crushed or broken stone (2517100055). Canada and the Bahamas are the leading suppliers — Canada by land-border proximity and the Bahamas by maritime proximity to US East Coast and Gulf ports, where large-scale quarry operations ship directly to coastal aggregate terminals.

The Bahamas hosts large-scale limestone quarrying operations on islands close to the US East Coast and Gulf of Mexico. The short sea voyage and purpose-built bulk loading terminals allow Bahamian suppliers to deliver crushed limestone aggregate to US coastal ports at competitive landed costs, making geography the primary competitive advantage rather than domestic demand.
The limestone line (2517100020) applies specifically to crushed or broken limestone (calcium carbonate-dominant stone) that is not in pebble or gravel form. All other crushed or broken stone — including granite chips, basalt screenings, and mixed quarry fines — falls under the NESOI line (2517100055). A mineralogical description or quarry certification identifying the stone type is the standard supporting document for making this determination.
