9902.12.32 - Camera flotation devices of vulcanized rubber other than hard rubber, cellular rubber or natural rubber, such devices measuring 6 to 9 cm in length, 4 to 6 cm in width and 2 to 6 cm in depth; the foregoing whether designed to encase the camera or to be attached to the camera by means of an adhesive pad (provided for in subheading 4016.99.60)

This HTS category, 9902.12.32, specifically designates camera flotation devices constructed from vulcanized rubber. The material composition is critical, excluding devices made of hard rubber, cellular rubber, or natural rubber. Furthermore, precise dimensional requirements are stipulated: the devices must measure between 6 to 9 cm in length, 4 to 6 cm in width, and 2 to 6 cm in depth. This classification applies regardless of whether the flotation device is designed to fully encase the camera or is intended to be attached via an adhesive pad. The "provided for in subheading 4016.99.60" notation indicates the underlying classification for these types of rubber articles, but this chapter 99 code provides a temporary modification or restriction.

Given the current hierarchical position within Chapter 99, which deals with temporary legislation and special provisions, the primary distinguishing factor for this code lies in its specific application as a temporary measure or restriction related to camera flotation devices. The sibling categories listed, such as live animals (Chapters 01), represent entirely different product groups and are therefore not directly comparable in terms of goods covered. The defining characteristics of this classification are its specialized product (camera flotation devices), specific material (vulcanized rubber meeting defined criteria), precise dimensions, and its placement under temporary tariff provisions.

As this HTS code (9902.12.32) represents a leaf node, there are no further subcategories within this specific classification. This means that once a product meets all the criteria outlined in the description – being a camera flotation device of vulcanized rubber within the specified dimensions and attachment methods – it falls directly under this HTS code, subject to the conditions of Chapter 99. The classification is therefore highly granular and relies on a strict adherence to the physical and material attributes detailed.
