HS Code for Double glazing

Double glazing, technically referred to as multiple-walled insulating units of glass, is classified under HS code 700800. This code is part of Chapter 70, which covers glass and glassware. Heading 7008 is a specific "monotextual" heading, meaning it has no subheadings and specifically describes these units. The classification applies to units consisting of two or more panes of glass separated by a gap of dehydrated air or other gases, hermetically sealed around the edges. This construction provides thermal and acoustic insulation. The classification remains 700800 regardless of whether the glass used is tempered, laminated, or coated (such as Low-E glass), provided the final product is a sealed unit. This classification is straightforward under GRI 1, as the product perfectly matches the heading description for multiple-walled insulating units.

Products Included

• Standard double-pane sealed units
• Triple-glazed insulating glass units
• Vacuum Insulated Glass (VIG) units
• Argon or Krypton filled insulating units
• Insulating glass with integrated blinds (sealed inside)
• Structural glazing units for curtain walls

Common Misclassification

A common misclassification occurs when double glazing is imported already installed in frames. If the glass is mounted in a frame (e.g., aluminum, wood, or PVC), it must be classified under the heading for the frame material, such as 7610 for aluminum windows or 4418 for wooden windows. Another error is classifying the panes separately under 7005 (float glass) or 7007 (safety glass); however, once they are sealed together as a unit, 700800 is the only correct code.

FAQ

What is the HS code for Double glazing?

The HS code for double glazing units is 700800, which covers multiple-walled insulating units of glass.

Does 700800 include the window frame?

No, 700800 only covers the glass unit itself. If the unit is framed, it is classified as a window under the respective material chapter (e.g., Chapter 76 for aluminum).
