HS Code for Blown glass sheets

Blown glass sheets are classified under HS code 7004.90 according to the nomenclature of Chapter 70, which encompasses glass and glassware. Heading 7004 specifically addresses drawn glass and blown glass, in sheets, whether or not having an absorbent, reflecting, or non-reflecting layer, but not otherwise worked. The process of blowing glass into sheets—often involving the creation of a large cylinder that is subsequently split and flattened—is a traditional method that distinguishes these products from float glass or cast glass. Subheading 7004.90 is the residual category for glass that has not been colored throughout the mass (body tinted), opacified, flashed, or coated with specific functional layers. The classification depends on the manufacturing method (blowing) and the physical form (sheets) rather than the final application, provided the glass has not been further processed into safety glass or multiple-walled insulating units. This code is essential for identifying artisanal or specific architectural glass products.

Common Misclassification

Blown glass sheets are often misclassified under 7005.29, which refers to float glass. Float glass is manufactured by floating molten glass on a bed of molten metal, a process entirely different from blowing. Another common error is 7003.19, which covers cast or rolled glass. If the glass has been further worked, such as being tempered or laminated, it must be moved to heading 7007. Furthermore, if the glass is body-tinted or flashed, it should be classified under 7004.20 rather than 7004.90. Importers must verify the manufacturing process to ensure the distinction between drawn/blown, cast, and float glass is maintained.

FAQ

What is the HS code for blown glass sheets?

The HS code for unworked, non-tinted blown glass in sheets is 7004.90.

Is stained glass classified under this code?

No, stained glass or glass colored throughout the mass (body tinted) is typically classified under 7004.20 if it is blown or drawn.
