4911.91.30.00 - Over 0.51 mm in thickness 🖩

This HTS category, 4911.91.30.00, specifically covers lithographs on paper or paperboard that are printed and are over 0.51 millimeters in thickness. These items fall under the broader classification of "Pictures, designs and photographs" which are themselves a subset of "Other printed matter." The "lithographs" designation signifies a printing process using a flat stone or metal plate, and the material specified is paper or paperboard.

The key distinguishing characteristic of this category from its sibling, 4911.91.20, is the physical thickness of the printed material. While both are lithographs, this heading applies only to those exceeding 0.51 mm, whereas 4911.91.20 applies to those not exceeding this thickness. This distinction is a critical factor for accurate classification and duty assessment.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, the focus for classification under this code rests entirely on confirming the item is a lithograph printed on paper or paperboard, and that its thickness surpasses the 0.51 mm threshold. Examples could include thick art prints, decorative posters, or heavy-stock photographic reproductions produced via lithography.
