HS code for Window glass sheets: 7004.90
Glass, drawn and blown, in sheets, (other than glass coloured throughout the mass (body tinted), opacified, flashed or having an absorbent, reflecting or non-reflecting layer).
Classification of window glass sheets under HS 7004.90
Window glass sheets produced through the drawing or blowing process are classified under HS code 7004.90. Heading 7004 specifically covers drawn glass and blown glass in sheets, whether or not they have an absorbent, reflecting, or non-reflecting layer, provided they have not been otherwise worked. The classification is driven by the manufacturing process. Drawn glass is made by pulling the molten glass vertically or horizontally from a furnace, while blown glass is produced by mechanical or mouth-blowing into a cylinder that is then flattened. Subheading 7004.90 is the residual category for glass that is not colored throughout the mass (body tinted), opacified, flashed, or coated with an absorbent or reflecting layer. This classification follows GIR 1 and the specific process-based headings of Chapter 70.

Codes often confused with 7004.90
Common mistake. The most frequent misclassification is with HS code 7005, which covers float glass. Float glass is the most common modern window glass, produced by floating molten glass on a bed of molten tin. While they look similar, the manufacturing process is different, and 7005 is the correct code for float glass. Another common error is using 7007 for safety glass; if the glass has been tempered or laminated to prevent shattering, it must be classified under 7007. Additionally, if the glass is already cut to a non-rectangular shape or has beveled edges, it may be classified under 7006.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
