Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If colored filaments are used
Colored closed woven fabrics of rovings fall under 7019.61.20, separate from uncolored high-silica variants.
If silica content is 93% or less
Lower silica content woven glass fabrics are classified as mineral wools or general glass textiles in heading 6806.
If sold as pre-cut panels or mats
Fabrics processed into specific shapes or articles shift from woven fabric heading to 7019.40 for glass fiber articles.
