9902.17.18 - Projection screens, each measuring 11 m or more but not over 22 m in width, of acoustically transparent perforated material (provided for in subheading 9010.60.00)

This HTS category, 9902.17.18, specifically covers large projection screens. The key defining characteristics for inclusion are their substantial width, ranging from 11 meters to a maximum of 22 meters, and their construction from acoustically transparent perforated material. The parenthetical note directing to subheading 9010.60.00 indicates that these screens are considered projection screens, implying a primary use in projecting images or visuals.

Distinguishing this category from its sibling categories, which represent a vast array of live animals and other commodities, is straightforward. Unlike general merchandise or other types of equipment, this classification is highly specialized, focusing on a niche product with precise physical dimensions and material properties. Its position within Chapter 99 signifies its status as a temporary provision, likely related to specific trade agreements or legislative actions, rather than a permanent classification within the main body of the HTS.

As a leaf node, HTS 9902.17.18 does not have further subcategories. Classification under this code is final if the goods meet the defined criteria of size and material. Therefore, import or export professionals must ensure that the projection screens in question precisely match the 11 to 22 meter width requirement and are made of acoustically transparent perforated material to correctly apply this temporary provision.
