Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sulfite wrapping paper with >40% sulfite fibers and burst index ≥1.47
Sulfite process vs. sulfate kraft changes pulp heading per subheading specs.
If not specifically for electrical condensers
Same weight kraft but general 'other' vs. condenser tissue sub-subheading.
If printed with patterns dominating over paper use
Chapter notes send printed motif paper to Chapter 49 if not subsidiary.
