In plain English
This category includes pumice stone, emery, natural corundum, natural garnet, and other natural abrasives, regardless of whether they have been heat treated. The goods are divided into two groups based on their specific type. One group consists solely of pumice stone, while the other covers emery, natural corundum, natural garnet, and all remaining natural abrasives.
