4810.39.30.00 - Cards, not punched, for punchcard machines, whether or not in strips

This HTS category, 4810.39.30.00, specifically covers cards that are not punched and are intended for use with punchcard machines. These cards may be presented individually or in continuous strips. The material composition is paper or paperboard, coated on one or both sides with kaolin (China clay) or other inorganic substances, without any additional coatings. This designation excludes paper products with writing, printing, or other graphic purposes.

Distinguishing this category from its sibling, 4810.39.65.00 (Other), is crucial. While both fall under the "Other" designation within the broader kraft paper and paperboard classification, 4810.39.30.00 is defined by its specific function as a card for punchcard machines. The sibling category likely encompasses other kraft paper or paperboard products not otherwise specified that do not meet the specific functional criteria of punchcard cards.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification into 4810.39.30.00 relies solely on the verification of the product's physical characteristics and intended use as a non-punched card for punchcard machinery, in addition to meeting the general coating and material requirements of heading 4810.
