9902.17.15 - Projection lenses, each with focal length of 1.13 m or more but not over 36.94 m and a throw ratio of 0.66 m or more but not over 9.23 m, the foregoing not exceeding 8 kg in weight (provided for in subheading 9002.11.40)

This HTS category, 9902.17.15, specifically addresses projection lenses that meet precise technical specifications. The criteria for inclusion are a focal length ranging from 1.13 meters to 36.94 meters, and a throw ratio between 0.66 meters and 9.23 meters. Additionally, these lenses must not exceed 8 kilograms in weight. This classification is relevant for these specialized projection lenses, as indicated by the parenthetical reference to subheading 9002.11.40, which likely covers photographic and projection lenses more broadly.

The parent category, Chapter 99, signifies that this classification falls under temporary legislation or temporary modifications, often implemented for specific trade agreements or policy objectives. This distinguishes it from the permanent HTS structure governing general merchandise. While the sibling categories at the HTS Root level encompass a vast array of live animals, this particular node is highly specific to a niche industrial or professional optical component, highlighting the specialized nature of Chapter 99 entries.

As a leaf node, HTS code 9902.17.15 has no further subdivisions. Therefore, the focus for classification under this code is on meticulously verifying the physical and performance characteristics of the projection lens against the defined focal length, throw ratio, and weight limitations. Any projection lens meeting these exact parameters and falling under a temporary legislative provision would be classified here, distinct from lenses with different specifications or those not subject to such temporary measures.
