4910.00 - Calendars of any kind, printed, including calendar blocks:

This category, HTS 4910.00, encompasses a wide array of printed calendars. It includes items designed to display dates in a structured format, regardless of their physical presentation, such as wall calendars, desk calendars, perpetual calendars, and calendar blocks. The primary unifying characteristic is that these items are printed and serve the function of time tracking or planning.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike other categories in Section X that cover printed books, newspapers, or pictures, HTS 4910.00 specifically targets products whose primary purpose is calendrical. For instance, while a magazine might contain a calendar insert, the primary classification would be for magazines (Chapter 4902), not calendars. Similarly, artwork featuring a calendar motif would likely be classified under "pictures" (Chapter 4911) if its artistic merit is paramount, whereas a printed calendar with decorative elements would fall under 4910.00.

Within HTS 4910.00, subcategories are established to provide further specificity. The distinction between calendars printed via lithographic process and other printing methods (represented by 4910.00.60.00) is a key differentiator. Lithographic printing, known for its distinct quality and application, requires a separate classification to reflect the manufacturing technique employed. This allows for granular tracking and tariff application based on the method of production.
