HS Code for Colored sheet glass

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.

Common Misclassification

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.

FAQ

What is the HS code for Colored sheet glass?

The HS code for colored, opacified, or flashed drawn and blown glass in sheets is 7004.20.

How is drawn glass different from float glass?

Drawn glass (7004) is pulled from the furnace and may have slight distortions, while float glass (7005) is floated on molten tin to achieve a perfectly flat surface.
