HS code for Colored sheet glass: 7004.20
Glass, drawn and blown, in sheets, coloured throughout the mass (body tinted), opacified, flashed or having an absorbent, reflecting or non-reflecting layer, but not otherwise worked.
Classification of colored sheet glass under HS 7004.20
The classification 7004.20 pertains to drawn and blown glass in sheets. Unlike the more common float glass found in heading 7005, drawn glass is produced by pulling the molten glass vertically or horizontally from a furnace, while blown glass is created by expanding a glass cylinder which is then cut and flattened. This subheading specifically covers glass that is 'coloured throughout the mass,' opacified, flashed, or has an absorbent or non-reflecting layer. 'Flashed' glass refers to a base layer of clear glass covered with a thin layer of colored glass, a technique often used in decorative applications. 'Opacified' glass is rendered opaque through the addition of materials like fluorine or phosphates. To qualify for 7004.20, the glass must remain in 'sheets' and must not be 'otherwise worked.' This means it cannot be beveled, engraved, drilled, or framed. The drawn glass process often leaves slight 'draw lines' or waves, which are characteristic of this manufacturing style and distinguish it from the perfectly flat float glass. This type of glass is often used in restoration projects for historical buildings or in specific artistic applications where the optical characteristics of traditional glassmaking are desired.

Codes often confused with 7004.20
Common mistake. The most common misclassification is with 7005.21, which covers float glass. While both can be colored throughout the mass, the manufacturing process (drawn/blown vs. float) is the deciding factor. It is also confused with 7004.90, which is for ordinary drawn or blown glass that is not colored, opacified, or flashed.

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).
