HS Code for Triple glazing

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.

Products Included

Common Misclassification

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.

FAQ

What is the HS code for Triple glazing?

The HS code for triple glazing units (multiple-walled insulating glass) is 7008.00.

Does HS code 7008.00 include the window frame?

No, 7008.00 only covers the glass unit. If the triple glazing is already fitted into a frame, it is classified as a window under the heading for the frame material (e.g., Chapter 44, 73, 76, or 39).
