Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sized for warp requirements
Warp-specific sized yarns have narrower subheadings.
If combined with conductive elements
Insulated wire/cable assemblies move to Chapter 85 electrical insulators.
If laminated with textile materials
Textile-glass laminates become tire cord fabric in Chapter 59.
