Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If bleached kraft paper for writing/printing
If suitable for graphic purposes, shifts from 'other than writing/printing' to 4811 bleached kraft paper.
If kraftliner meeting Mullen strength table
High-strength kraftliner >115 g/m² with sulfate fibers goes to 4804.11, not coated cards.
If printed with motifs primary to use
Chapter note moves printed paper with primary pictorial elements to Chapter 49 printed books/ matter.

Import Tips & Compliance
• Include dimensional specs (e.g
• 80-column 3.25x7.375 inches) in import docs to prove punchcard machine compatibility
• Test for Mullen burst strength if resembling kraftliner specs, but confirm not exceeding 115 g/m² limits for 4804
• Label clearly as 'not punched' to prevent CBP reclassification as finished data media
