Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If granite granules under 2 mm
Finer granules from heading 2516 granite move to 2517.10 only if specifically for concrete/road use.
If made from 2515/2516 stone granules or powder
Processed granules/chippings of marble/travertine have separate subheading even for same end uses.
If further processed into mosaic cubes
Chapter exclusions send worked marble/granite products to chapter 68 worked monumental stone.

Import Tips & Compliance
• Include engineering specs showing use for road metalling (AASHTO M43 grading) to distinguish from decorative stone
• Document quarry source and crushing process; heat-treated granite requires processing certificates
