4911.91 - Pictures, designs and photographs:

HTS code 4911.91 encompasses printed pictures, designs, and photographs that are not specifically enumerated or covered by other, more specific headings within Chapter 49. This category is broad and includes a variety of printed visual materials such as posters, prints, artistic reproductions, and photographic prints intended for display or decorative purposes, provided they do not fall under more specialized classifications.

This heading is distinguished from its sibling, 4911.99, which also falls under "Other printed matter." While 4911.99 covers other miscellaneous printed materials not elsewhere specified, 4911.91 specifically focuses on items that are primarily pictorial or photographic in nature. Therefore, the core differentiator lies in the predominant character of the printed material: visual representations in 4911.91 versus general printed matter in 4911.99.

The subcategories under 4911.91 further refine the classification based on the age of the printed material relative to the time of importation. Subcategory 4911.91.10.00 is for items printed over 20 years ago, often considered antiques or collectibles. The other branch, though not explicitly detailed here, will cover printed pictures, designs, and photographs produced more recently, within the 20-year period. This age-based distinction is critical for determining applicable duty rates and potential import restrictions.
