More Specific Codes
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 binder or sizing applied
Chemically treated yarns for processability classify as 'other' sized yarn.
If dyed or colored
Any coloring moves yarn to colored subheading regardless of other specs.
If drawn into bottles or containers
Glass in container forms falls under Chapter 70 heading 7010, not fibers.

Import Tips & Compliance
• Document chemical resistance properties and intended electrical use to support valuation
• Confirm yarn twist and ply count; multi-ply assemblies may require strand count declaration
• Beware bulk packaging misdeclared as mats (7019.19); verify loose yarn form
