Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If >=130 g/m² straw pulp with CMT 30 >1.4 N/g/m²
Direct subheading note match for straw-based corrugating medium.
If >40% sulfite wood fibers, machine-glazed, Mullen burst >=1.47 kPa·m²/g
Qualifies as sulfite wrapping paper if glazing and fiber specs apply.
If lower grammage under 150 g/m² but still fluting-purpose
Weight threshold drops it to other uncoated fluting paper subheading.

Import Tips & Compliance
• Document pulp composition (straw vs wood) to differentiate from wood-based subheadings; ash content tests help
• Sheets must be 'in rolls or sheets' per heading; ensure no cutting to size that triggers 4820 exclusion
