7007.21.51.00 - Other

This HTS category, 7007.21.51.00, encompasses laminated safety glass that is not specifically designated as windshields. It covers laminated glass panels that are intended for installation in vehicles, aircraft, spacecraft, or vessels, but which do not constitute the primary front-facing windshield component. The key characteristic is that the glass is laminated, meaning it consists of two or more layers of glass bonded together with an interlayer, providing enhanced safety by preventing shattering into sharp fragments upon impact.

Distinguishing this category from its sibling, 7007.21.11 (Windshields), is crucial. While both deal with laminated safety glass for transportation applications, this category specifically excludes windshields. Therefore, it would encompass items such as side windows, rear windows, sunroofs, and other glazed panels for these conveyances that are laminated for safety but are not the primary front windshield. The "Other" designation within this sub-heading signifies that it captures all laminated safety glass meeting the size and shape criteria for incorporation into vehicles, aircraft, spacecraft, or vessels, excluding the specific item already classified as a windshield.

As a leaf node, this category does not have further subdivisions. The classification hinges on the specific form and intended use of the laminated glass panel. Practical classification relies on identifying the panel's dimensions, shape, and whether it is designed for a position other than the windshield within the specified modes of transport.
