9902.12.54 - Camera cases with outer surface of transparent molded polycarbonate plastics, designed for cameras of subheading 8525.80.40; the foregoing each incorporating buttons for the operation of the camera, an opaque plastic base that clips into a camera mount, a thumb-screw on the base mount that allows for adjustment of the camera viewing angle on a pivot, a silicon gasket in the door of the case that allows for waterproof operation of the camera at a depth of not more than 40 m, a flat, optically-coated, glass lens and a heat sink to dissipate camera heat (provided for in subheading 4202.99.90)

This HTS code, 9902.12.54, represents a highly specific classification for protective camera cases. These cases are designed with a transparent molded polycarbonate plastic outer shell and are intended for use with cameras falling under subheading 8525.80.40. Key features that define eligibility for this classification include integrated buttons for camera operation, an opaque plastic base that securely attaches to a camera mount, a thumb-screw for adjustable camera viewing angles via a pivot, a silicon gasket enabling waterproof operation up to 40 meters, a flat optically-coated glass lens, and a heat sink for dissipating camera heat.

As a specialized provision within Chapter 99, this category addresses temporary legislation or modifications and is distinct from the broad product categories found in earlier chapters. While Chapter 42 covers various articles of leather, travel goods, and similar items, and other chapters might classify cameras themselves or their basic components, 9902.12.54 is reserved exclusively for these advanced, feature-rich camera protective housings that incorporate specific functionalities beyond simple containment. Its existence signifies a particular trade or policy consideration related to these specialized camera accessories.

Given that this is a leaf node within the HTS database, there are no further subdivisions or subcategories under 9902.12.54. Therefore, classification decisions for goods falling under this provision will rely on a meticulous assessment against all the detailed physical and functional criteria outlined in its description. Any item not meeting *all* specified requirements, such as lacking the waterproofing gasket, heat sink, or specific mounting mechanism, would need to be classified elsewhere, likely under a more general provision for camera cases or protective equipment if applicable.
