Product classification
HS code for Triple glazing: 7008.00
Glass, multiple-walled insulating units of glass.
Classification of triple glazing under HS 7008.00
Triple glazing is classified under HS code 7008.00, which covers multiple-walled insulating units of glass. The classification is based on the product's construction: three panes of glass separated by spacers and hermetically sealed to create insulating cavities filled with air or inert gas (such as argon). According to the Explanatory Notes for Chapter 70, these units are treated as a single composite article. The primary function of the unit is thermal and acoustic insulation, which is the defining characteristic of heading 7008. This code applies regardless of the type of glass used (e.g., tempered, laminated, or low-E coated), provided the panes are joined into a permanent, multiple-walled unit. The classification remains consistent for both double and triple-layered units.

Codes often confused with 7008.00
Common mistake. Triple glazing is frequently misclassified under HS code 7005 (float glass) or 7007 (safety glass) if the multiple-walled nature is ignored. More significantly, if the glass unit is imported already installed in a frame, it must be classified according to the frame material, such as 7610.10 for aluminum windows or 4418.10 for wooden windows. HS code 7008.00 only applies to the glass unit itself, not the complete window assembly.

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).
