Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If 60-115 g/m² with sack kraft specs (Mullen burst index >=3.7 kPa·m²/g)
Lighter weight and matching sulfate fiber/tear/tensile minima define it as sack kraft paper.
If mainly recovered waste paper pulp with Mullen burst index >=2 kPa·m²/g
Subheading note specifies testliner from recycled pulp, common alternative for eco-friendly fluting.
If surface-sized or minimally processed beyond Note 3 limits
Any further working like sizing moves it out of heading 4805 to paperboard provisions.

Import Tips & Compliance
• Include corrugator compatibility specs and burst test results in documentation to prove fluting end-use
• Avoid common error of declaring as 'packaging paper' which shifts to 4804; specify 'fluting medium' clearly
• Check for minimum order quantities from suppliers; bulk rolls require proper hazardous material declarations if treated
