HS code for Insulated glass units: 7008.00
Glass, multiple-walled insulating units of glass.
Classification of insulated glass units under HS 7008.00
Insulated glass units (IGUs) are classified under HS code 7008.00. This classification is straightforward as the heading specifically describes "multiple-walled insulating units of glass." These products consist of two or more panes of glass separated by a spacer and sealed to create a hermetically sealed air or gas space between the layers. This construction provides thermal and acoustic insulation. The classification under 7008.00 is mandatory for these assembled units, regardless of the type of glass used (e.g., tempered, laminated, or coated) or the type of gas used in the cavity (e.g., argon or krypton). The key factor is the assembly into a single, permanent insulating unit. The hermetic seal is a critical technical requirement for 7008.00. If the panes are simply held together by a frame without a permanent seal, they would not qualify as an insulating unit under this heading. This code is essential for distinguishing high-performance architectural glass from standard single-pane glass.

Codes often confused with 7008.00
Common mistake. A common error is classifying these units under HS code 7005 (Float glass) or 7007 (Safety glass). While the individual panes might be float or safety glass, once they are joined into a multiple-walled unit, they must be classified under 7008.00. Another misclassification occurs when the glass is already mounted in a frame. If the unit is imported with a frame (aluminum, wood, or PVC), it should be classified under the respective heading for the frame material, such as 7610 for aluminum windows or 3925 for plastic windows.
Top exporters and importers of HS 700800 (the code used for insulated glass units), 2025
In 2025, the largest exporter of HS 700800 (the code used for insulated glass units) in UN Comtrade data was Germany, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
