Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-woven mats of rovings instead of woven
Mechanically bonded but non-woven formats fall under 7019.52, distinct from closed weaves.
If pre-impregnated with insulating compounds
Insulated wire/fabric combinations classify as electrical insulators in Chapter 85.
If treated with rubber for conveyor belting
Rubber treatment moves to Chapter 59 as textile fabric of rubber.
