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
