8479.71.00.00 - Of a kind used in airports

This HTS category, 8479.71.00.00, specifically encompasses passenger boarding bridges designed and utilized for operations within airports. These are the covered walkways that connect aircraft to airport terminals, facilitating the embarkation and disembarkation of passengers. The defining characteristic for inclusion in this classification is their intended use in the airport environment to manage passenger flow between the terminal building and an aircraft.

This category is distinguished from its sibling, 8479.79.00.00, which covers "Other" passenger boarding bridges. While 8479.71.00.00 is dedicated to airport-specific applications, the "Other" category would likely encompass passenger boarding bridges used in non-airport settings, or those with auxiliary functions not solely related to typical airport passenger transit. The classification hinges on the primary operational context and design for airport infrastructure.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification within 8479.71.00.00 is therefore definitive for passenger boarding bridges whose functional design and primary application are explicitly for airport terminals. The focus remains on the purpose-built nature of these structures for airport infrastructure and passenger mobility.
