Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If glass fiber predominant
Washers primarily of glass fibers classify as glass textiles rather than other minerals.
If building insulation grade
Fabrics of rock wool primarily for insulation fall under Chapter 68 heading 6812.
If pump brake applications
Friction washers for pumps classify as pump parts.
