Import Tips
• Verify kaolin or inorganic coating coverage and weight via lab testing to confirm classification under 4810, avoiding misclassification as uncoated paper in 4802
• Provide manufacturer specs confirming dimensions (e.g
• 3.25x7.375 inches) and 'for punch card machines' labeling to support HTS 4810.99.30.00 entry
• Watch for common pitfalls like strips exceeding rectangular sheet limits or pre-punching, which shifts to 4823 or heading 8473 parts
