Import Tips & Compliance
• Ensure the unit is sealed and tested for thermal performance, as CBSA may require proof of insulation
• Declare the gas fill (e.g
• argon or krypton) and spacer type accurately
• Check if the unit requires special handling due to its large size during customs inspection

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.
Custom 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.
Double-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.
Fire-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.
Low-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.
Solar 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.
