HS Code 7008.00 – Glass; multiple-walled insulating units of glass
HS code 7008.00 is the 6-digit subheading for glass, multiple-walled insulating units of glass. It is used for double-glazed windows, triple-glazed windows, low-emissivity (Low-E) IGUs, argon-filled insulating glass and sound-reducing IGUs.
What HS 7008.00 covers
This HS code covers multiple-walled insulating units of glass, commonly known as Insulated Glass Units (IGUs) or double/triple glazing. These units consist of two or more panes of glass separated by a spacer and sealed, creating an insulating air or gas-filled space. Their primary function is to enhance thermal and acoustic insulation in buildings, significantly improving energy efficiency and occupant comfort. Major traders include window and door manufacturers, architectural glass suppliers, and construction material distributors. Key trade considerations involve U-value (thermal transmittance), solar heat gain coefficient (SHGC), and compliance with regional energy efficiency standards and building codes. The global push for sustainable construction and reduced energy consumption drives the international trade of these essential building components.

Codes often confused with 7008.00
Common mistake. Could be confused with other flat glass codes like 7005 (float glass) if not recognized as a finished insulating unit, or 7007 (safety glass) if the IGU also incorporates safety features.
Top exporters and importers of HS code 700800, 2025
In 2025, the largest exporter of HS code 700800 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).
