Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fiberglass dominates as woven fabric with minor paper
Woven glass fiber fabrics take precedence; paper must be primary.
If made from recovered pulp without reinforcement
Testliner from waste paper in 4805; scrim makes it composite 4807.
If assembled into electrical insulating article

Import Tips & Compliance
• Certify fiberglass as non-woven reinforcement to prevent plastics chapter misclassification
• Declare electrical end-use but emphasize paper as principal material
• Test for impregnation; any varnish coating shifts to 4811 or 8547 composites
