More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specific to rolling stock brake systems
Railway-specific friction parts fall under Chapter 86 regardless of material.
If considered worked building stone blocks
Chapter notes exclude monumental stone, but large mineral blocks could misclassify there.
If sold as brake fluids or compounds
Chemical friction compounds/fluids classify under Chapter 38 cut-back materials.
