Import Tips
• 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
