Heavyweight Semichemical Fluting Medium Paper from Japan

Uncoated fluting paper in rolls, weighing 180 g/m², made from at least 65% unbleached hardwood fibers via combined mechanical and chemical pulping, with CMT 30 crush resistance over 1.8 N/g/m². Used as the corrugated medium in manufacturing double-wall cardboard boxes for heavy-duty shipping. Falls under 4805.19.20.00 as fluting paper over 150 g/m², not meeting the specific semichemical criteria of 4805.11.

Import Tips

Verify grammage exceeds 150 g/m² via certified lab tests; common pitfall is misclassification under lighter weight subheadings

Provide mill test certificates confirming fluting properties and fiber content to avoid reclassification as general kraft paper

Ensure rolls are not further worked (e.g

no printing or coating) per Note 3 to Chapter 48 for proper 4805 entry
