Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If bonded into wheels, disks or sticks
Bonded abrasive products using natural garnet as grains shift to heading 6805 for artificial/monolithic abrasives.
If in crude unprocessed form
Pumice stone in blocks or lumps goes to 2513.10, while sized garnet grit is processed enough for the 'other' subheading.
If calcined/heat-treated beyond mere sizing for refractory use
Extensively processed natural abrasives for refractory bricks may classify under Chapter 69 ceramics.

Import Tips & Compliance
• Verify mineral composition via lab assay to confirm natural origin, excluding synthetic abrasives which fall under Chapter 68
• Include heat-treatment certification if applied, as allowed by heading, but document to prevent confusion with processed goods
• Avoid common pitfall of classifying as manufactured articles (6805) if merely sized or heat-treated without bonding
