Bleached Kraft Punchcard Machine Cards
Rectangular cards made from bleached kraft paperboard, coated with kaolin on both sides, weighing 150 g/m² or less, with over 95% chemical wood fibers. These not-punched cards are designed for use in punchcard machines for data processing and are supplied in strips or sheets. They fall under HTS 4810.31.30.00 due to their specific coating, fiber content, weight, and intended use as punchcard blanks.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically for punchcard machines
Cards not designated for punchcard use fall under the broader 'other' subheading in the same bleached kraft category.
If loose sheets or cards cut to size, not in rolls/strips for machines
Heading 4820 excludes rolls/sheets but covers loose, cut-to-size cards not of heading 4814/4821.
If unbleached kraft paperboard
Unbleached versions shift to 4804.51, lacking uniform bleaching throughout the mass.

Import Tips & Compliance
• Verify coating is solely kaolin or inorganic substances with no other coatings via lab testing to confirm classification
• Provide mill test certificates proving >95% chemical wood fiber content and uniform bleaching throughout the mass
• Avoid misclassification as printed cards by ensuring no motifs or graphics that are primary to use, per Chapter 49 note
