Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of filaments with 93% or less silica
Lower purity silica fabrics classify under 7019.62, separate from ultra-high purity >93%.
If further processed into articles like tapes
Fabrics cut or sewn into specific articles move to 7019.90 for other glass fiber products.
If other mechanically bonded non-wovens
Non-woven mechanically bonded mats or felts fall under 7019.51 if not closed woven.
