This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as chopped strands
Chopped glass strands under 6mm length classify separately from continuous yarn.
If filaments under 5.5 decitex
Finer filament yarns have distinct subheading based on decitex measurement.
If formed into panels or boards
Glass fiber products made into structural panels shift to Chapter 68 as worked articles.
