Argon-Filled Double-Glazed Window Unit
An argon-filled double-glazed window unit consists of two glass panes sealed with a spacer, with argon gas injected between them to reduce thermal conductivity. This construction makes it a multiple-walled insulating unit of glass, classified under tariff item 7008.00.00. The argon fill enhances the insulating performance, a key characteristic of this heading.
7008.00.00Custom Curved Insulated Glass Unit
A custom curved insulated glass unit is a bent double-pane glass assembly, sealed after annealing to create a multiple-walled insulating structure for arched or curved windows. The curvature does not remove it from heading 70.08, as it remains a multiple-walled insulating unit of glass. The sealing process ensures the insulating air space is maintained, aligning with the heading's scope.
7008.00.00Double-Pane Insulated Glass Unit
A double-pane insulated glass unit consists of two glass panes separated by an air or gas-filled spacer, sealed to reduce heat transfer in windows. This product is a classic multiple-walled insulating unit of glass, falling directly under tariff item 7008.00.00. The primary function is thermal insulation, which is the defining characteristic of this heading.
7008.00.00Fire-Rated Glazed Insulating Unit
A fire-rated glazed insulating unit is a multiple-walled glass assembly with intumescent layers between panes, providing fire resistance for 20-60 minutes in partitions. Despite the fire-resistant properties, it remains a multiple-walled insulating unit of glass, classified under tariff item 7008.00.00. The insulating air space and glass walls are essential to its function, and fire resistance is an added performance feature.
7008.00.00Low-E Coated Insulated Glass Panel
A low-E coated insulated glass panel is a double-walled glass unit with a low-emissivity coating on an inner surface to reflect infrared heat while allowing visible light. The coating enhances the insulating performance, but the product remains a multiple-walled insulating unit of glass under tariff item 7008.00.00. The sealed air space and multiple panes are the primary insulating mechanism.
7008.00.00Patio Door IG Unit
A patio door IG unit is a large-format double-glazed glass assembly designed for sliding doors, typically gas-filled for enhanced insulation. This product is a multiple-walled insulating unit of glass, classified under tariff item 7008.00.00. The large size and gas fill do not alter its classification, as the insulating structure is the defining feature.
7008.00.00Solar Control Insulated Glass Unit
A solar control insulated glass unit is a double-glazed assembly with a sputtered solar control coating to block UV and reduce heat gain. The coating improves performance, but the product is a multiple-walled insulating unit of glass, falling under tariff item 7008.00.00. The sealed air space and multiple panes provide insulation, with the coating as an enhancement.
7008.00.00Soundproof Multiple-Walled Glass Unit
A soundproof multiple-walled glass unit features asymmetric pane thicknesses and a tuned air space to reduce noise transmission in urban windows. While acoustic insulation is a key benefit, the product is a multiple-walled insulating unit of glass, classified under tariff item 7008.00.00. The thermal insulation function is inherent, and the acoustic properties are secondary.
7008.00.00Triple-Glazed Insulating Glass Unit
A triple-glazed insulating glass unit consists of three glass panes and two sealed chambers filled with inert gas for superior thermal insulation. This advanced multiple-walled unit falls under tariff item 7008.00.00, as it is a multiple-walled insulating unit of glass. The additional pane and chamber enhance insulation, but the classification remains unchanged.
7008.00.00Vacuum Insulated Glass Unit
A vacuum insulated glass unit is an ultra-thin multiple-walled glass assembly with a vacuum between panes, providing exceptional R-value insulation in slim profiles. The vacuum creates a highly effective insulating barrier, but the product remains a multiple-walled insulating unit of glass under tariff item 7008.00.00. The multiple glass walls and sealed vacuum space are the defining features.
