Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as ready polishing compound set
Complete polishing sets or compounds with abrasives classify under Chapter 82 as interchangeable tools.
If specifically for rubber or tire industry
Zinc dust designated for rubber activator use has its own subheading.
If alloyed with other metals exceeding 2.5%
Zinc alloys are classified differently per chapter note (b), not pure zinc dust.
