Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If semichemical fluting with hardwood ≥65% and CMT >1.8 N/g/m²
Fluting medium paper under 4805.11 if corrugating specs met, not dielectric.
If >40% sulfite pulp, ash ≤8%, burst ≥1.47 kPa·m²/g
Sulfite wrapping paper shifts to 4805.30 if meeting those process specs.
If printed and further cut for retail
Processed into hung wallpaper or similar articles under 4821.

Import Tips & Compliance
• Conduct pre-shipment thickness uniformity tests; variances can lead to rejection as non-condenser
• Declare exact end-use as electrical to differentiate from packaging papers
• Monitor for chapter 49 if any printing exceeds subsidiary use
