Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If textured or in yarn form
Textured glass fiber yarns are classified separately under 7019.11, while smooth rovings remain in 7019.90
If silica content below 60% without qualifying oxides
Fails Chapter 70 glass wool/fiber definition, shifting to mineral wools in Chapter 68
If imported as woven fabric rather than roving
Woven glass fiber fabrics move to 7019.40 subheading
