Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If machine-finished but different finish type
4804.21 is specifically machine-finished; other finishes stay in 4804.29.
If ≥65% semichemical hardwood fibers
Different pulping process (mech+chem) classifies as fluting paper.
If coated on one/two sides post-production
Any coating removes from uncoated kraft heading 4804.

Import Tips & Compliance
• Submit fiber analysis proving chemical sulfate/soda dominance over mechanical pulp
• Avoid printing motifs that dominate use; shifts to chapter 49 per notes
• Ensure roll form; sheets cut to size may require 4823 if for Jacquard/perforated use
