Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If open weave or needle-punched
Non-closed woven or mechanically bonded non-woven fabrics go to 7019.59, not closed woven rovings.
If imported as yarn or roving only
Unwoven rovings or yarns of high-silica filaments classify under 7019.11 before fabric production.
If coated with rubber or plastics
Textile fabrics impregnated or coated with plastics shift to Chapter 59 headings.
