Products classified under HTS 7008.00.00.00
Argon-Filled Double-Glazed Window Unit
A sealed double-pane glass unit filled with argon gas between panes to minimize thermal conductivity, commonly used in energy-efficient fenestration. It qualifies for HTS 7008.00.00.00 as a multiple-walled insulating unit where the glass walls provide the insulating function via gas encapsulation. Prevents condensation and improves acoustics.
Soundproof Multiple-Walled Glass Unit
Insulated glass unit with asymmetric pane thicknesses and air space tuned for noise reduction in urban windows. HTS 7008.00.00.00 applies as multiple-walled glass for insulation, with acoustic benefits secondary. Common in hotels near airports.
Fire-Rated Glazed Insulating Unit
Multiple-walled glass with intumescent layers for 20-60 min fire resistance in partitions. HTS 7008.00.00.00 for insulating walls of glass. Building code compliant.
Custom Curved Insulated Glass Unit
Bent double-pane unit for arched windows, sealed post-annealing. 7008.00.00.00 as multi-walled per note (a).
Patio Door IG Unit
Large-format double-glazed for sliding doors, gas-filled. Pure 7008 classification.
Double-Pane Insulated Glass Unit
A multiple-walled insulating unit consisting of two glass panes separated by an air or gas-filled spacer, designed primarily for use in windows to reduce heat transfer. It falls under HTS 7008.00.00.00 as it is a multiple-walled insulating unit of glass, meeting the definition without further processing beyond assembly. These units enhance energy efficiency in residential and commercial buildings.
Triple-Glazed Insulating Glass Unit
An advanced multiple-walled unit with three glass panes and two sealed chambers filled with inert gas for superior thermal insulation in high-performance windows. Classified under HTS 7008.00.00.00 due to its multi-layered glass construction designed specifically for insulation. Ideal for cold climates or energy-efficient building codes.
Low-E Coated Insulated Glass Panel
Double-walled glass unit with low-emissivity coating on one inner surface to reflect infrared heat while allowing visible light transmission. Falls under HTS 7008.00.00.00 as the primary function is insulation via multiple walls, with coating as a secondary feature per chapter notes. Used in skylights and curtain walls.
Vacuum Insulated Glass Unit
Ultra-thin multiple-walled glass unit with a vacuum between panes for exceptional R-value insulation in slim window profiles. Classified in HTS 7008.00.00.00 for its multiple glass walls providing insulation, regardless of vacuum technology. Suited for historic building retrofits.
Solar Control Insulated Glass Unit
Double-glazed unit with sputtered solar control coating to block UV and heat gain in sunny climates. Under HTS 7008.00.00.00 for multi-wall insulation, coating enhances performance per chapter note (b). For commercial facades.
