Subheadings
Products classified under HTS 2517.10.00
Railway Ballast Crushed Stone
Hard crushed stone, typically basalt or granite sized 1.5-2.5 inches, used as railway ballast to support tracks and facilitate drainage. Meets HTS 2517.10.00 criteria as broken stone for railway ballast applications. Angular shape from crushing prevents shifting under load.
Basalt Concrete Aggregate
Crushed basalt stone aggregate with excellent compressive strength, sized for ready-mix concrete production. HTS 2517.10.00 classification due to primary use in concrete aggregates and road base. Dark color from natural iron content.
Crushed Marble Road Metal
Crushed marble chips used as road metalling material in rural roads and driveways, providing white decorative surface course. Although marble originates from heading 2515, crushing for road use brings it under HTS 2517.10.00. Angular particles ensure good compaction.
Washed Sea Shingle Ballast
Washed sea shingle consisting of rounded pebbles collected from coastal areas, sized for railway or crane mat ballast applications. HTS 2517.10.00 explicitly includes shingle for ballast uses. Natural salt content removed by washing.
Quartzite Crushed Road Aggregate
High-silica quartzite crushed to 1-2 inch size for road shoulder and base course construction. Exceptional hardness makes it ideal for heavy traffic roads under HTS 2517.10.00. Heat-treated versions improve frost resistance.
Gneiss Railway Ballast
Metamorphic gneiss crushed to AREMA #4 ballast specification for mainline railway track support. Provides excellent lateral stability under HTS 2517.10.00 railway ballast provision. Banded appearance from mineral layering.
Traprock Concrete Coarse Aggregate
Dense traprock (diabase) crushed to 1-1/2 inch maximum size for structural concrete coarse aggregate. Superior bonding properties under HTS 2517.10.00 concrete aggregate use. Dark green-black color.
Heat-Treated Pebbles Concrete Mix
Heat-treated decorative pebbles specifically sized and tested for exposed aggregate concrete finishes in architectural applications. Dual use as concrete aggregate qualifies under HTS 2517.10.00. Treatment removes iron staining.
Crushed Limestone Gravel
Crushed limestone gravel consists of broken stones typically sized 3/8 to 3/4 inch, commonly used as concrete aggregate in construction projects. It falls under HTS 2517.10.00 because it is broken or crushed stone specifically intended for concrete aggregates, road metalling, or ballast applications. The material may be heat-treated to enhance durability.
Granite Road Base Aggregate
Granite road base aggregate is crushed granite stone graded for use in road metalling and base layers under asphalt or concrete pavements. Classified in HTS 2517.10.00 as broken or crushed stone designed for road construction applications. Often heat-treated to remove moisture and improve compaction.
River Pebbles for Concrete Aggregate
Smooth river pebbles graded 3/4 inch, washed and screened for use as coarse aggregate in concrete mixing. Falls under HTS 2517.10.00 as pebbles commonly used for concrete aggregates despite natural rounded shape. Minimal processing preserves natural integrity.
Heat-Treated Flint Shingle
Heat-treated flint shingle, crushed and screened for use in concrete aggregates or road surfacing, providing silica-rich durability. Specifically listed in HTS 2517.10.00 as shingle and flint suitable for construction aggregates. Thermal processing enhances fracture resistance.
