Basalt Granules 4-8mm from Japan
Basalt granules, sized 4-8mm, are produced by crushing basalt rock of heading 25.16 and are used in railroad ballast, concrete additives, or filtration media. The crushing and sizing are mechanical processes allowed by Chapter 25 Note 1. They are not heat-treated or mixed, so they are classified as granules of stones of heading 25.16 under this tariff item.

Import Tips
