HS Code 7003.20 – Glass; cast glass and rolled glass, wired sheets, whether or not having an absorbent or reflecting layer but not otherwise worked
HS code 7003.20 is the 6-digit subheading for glass, cast glass and rolled glass, wired sheets, whether or not having an absorbent or reflecting layer but not otherwise worked. It is used for wired patterned glass, wired clear glass, fire-rated wired glass, security wired glass and industrial wired glass.
What HS 7003.20 covers
This category covers cast or rolled glass sheets that incorporate an embedded wire mesh, providing enhanced safety and fire resistance. These non-otherwise-worked sheets are a critical component in construction, particularly for applications requiring robust glazing solutions. Major importers and exporters include specialized glass manufacturers, fire safety product suppliers, and large construction material distributors. The wire mesh prevents the glass from shattering into large, dangerous pieces upon impact or during a fire, making it ideal for skylights, fire doors, industrial windows, and security partitions. Understanding the "wired" characteristic and the "cast or rolled" manufacturing method is essential for accurate trade classification and compliance.

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. 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).
