Overview

This HTS classification, 9020.00.40.00, specifically designates underwater breathing devices that are self-contained and designed for individual use while submerged. These are complete units intended to be worn by the user to facilitate breathing underwater, without the need for external assistance or supervision. Examples include scuba diving regulators, rebreathers, and full-face masks with integrated air supply systems that meet these criteria. The key defining characteristic is the self-sufficiency and portability for a single operator during underwater activities.

This category is distinct from its sibling, 9020.00.60.00, which covers "Other breathing appliances and gas masks." While both fall under the broader heading of breathing apparatus, 9020.00.40.00 is narrowly focused on *underwater* applications and the complete, wearable unit concept. The "other" category (9020.00.60.00) would encompass a wider range of breathing devices, such as oxygen therapy equipment, industrial respirators not designed for underwater use, or gas masks for protection against airborne contaminants that are not part of a self-contained underwater breathing system.

As a leaf node, 9020.00.40.00 has no further subdivisions. Therefore, the classification hinges entirely on meeting the description's criteria: being an underwater breathing device, designed as a complete unit, portable, and not requiring attendants. Classification decisions will focus on the product's intended use, design for individual underwater operation, and its integrated nature as a self-contained breathing apparatus.
