Unpunched 80-Column IBM Punch Cards
Rectangular paper cards coated with kaolin on one or both sides, measuring 80 columns by 12 rows, designed specifically for IBM punch card machines like the 029 Key Punch. These cards are not pre-punched and may be supplied in strips for efficient feeding. They fall under HTS 4810.99.30.00 due to their coating and dedicated use in punch card data processing systems.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically designed for punch card machines
Cards for general office use or index purposes without punch machine compatibility fall into the broader 'other' category in the same subheading.
If sold as filter paper or for filtration apparatus
Coated paper cards intended for lab filtration rather than data processing are classified under paper filtration products.
If cut to loose sheets without punch card specifications
Chapter notes exclude loose sheets or cards not meeting punch card criteria from heading 4820, but generic cards shift here if not machine-specific.

Import Tips & Compliance
• 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
