4910.00.20.00 - Not over 0.51 mm in thickness

This HTS category encompasses calendars of all types that are printed, including those with removable calendar blocks, where the primary printing process is lithographic and the paper or paperboard used in their construction does not exceed 0.51 millimeters in thickness. This classification is specifically for calendars where the printing technique is lithography, a method involving the transfer of images from a plate to a printing surface. The defining physical characteristic for inclusion here is the thickness of the substrate.

The critical distinction for this category, as indicated by its sibling, lies in the thickness of the paper or paperboard. Calendars classified under 4910.00.20.00 are specifically for those printed on material that is 0.51 mm or less in thickness. Conversely, calendars printed using a lithographic process on paper or paperboard that exceeds 0.51 mm in thickness would fall under the sibling category 4910.00.40.00. Both categories fall under the broader heading for printed calendars, but the thickness of the substrate is the deciding factor for subclassification.

As this is a leaf node within the HTS, there are no further subdivisions under this specific code. Therefore, classification within this category relies solely on meeting the criteria of being a printed calendar, utilizing a lithographic printing process on paper or paperboard, and adhering to the specified maximum thickness of 0.51 mm. Examples include desk calendars, wall calendars, and promotional calendars produced with these characteristics.
