Screened Limestone Chippings from United States
Screened limestone chippings, angular in shape and sized at 3/4 inch minus, are used in asphalt mixes and landscaping drainage. They are processed from limestone of heading 2515 by crushing and screening, without further alteration, and serve as granules or chippings for concrete aggregates or road metalling. This places them under tariff item 2517.10.00, which covers such stone products whether or not heat-treated.

Import Tips
• Ensure the chippings are not calcined or mixed with binders, as that would shift classification
• Declare the weight in kilograms or tonnes as per the invoice, and keep a mill certificate showing the stone's origin and processing
• If the chippings are for agricultural lime, verify if a different tariff item applies
