Crushed Limestone Gravel from China

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.

Import Tips

Verify particle size distribution meets ASTM C33 standards for concrete aggregates to ensure proper classification under 2517.10.00

Provide geological origin certification and heat-treatment records if applicable to avoid reclassification as mere pebbles
