Product classification
HS code for Wired glass sheets: 7003.20
Glass, cast glass and rolled glass, wired sheets, whether or not having an absorbent or reflecting layer but not otherwise worked.
Classification of wired glass sheets under HS 7003.20
Wired glass sheets are classified under HS code 7003.20 because they are a specific form of cast or rolled glass that incorporates a wire mesh or grid during the manufacturing process. According to the General Rules of Interpretation (GRI) 1 and 6, classification is determined by the terms of the headings and subheadings. Heading 7003 covers cast glass and rolled glass, in sheets or profiles, whether or not having an absorbent, reflecting, or non-reflecting layer, but not otherwise worked. The inclusion of a wire mesh is a primary characteristic that distinguishes this product from standard float glass or plain cast glass. The wire is embedded into the glass while it is in a molten or semi-molten state, typically to provide structural integrity and fire-resistant properties. This classification applies as long as the glass has not been further processed, such as being ground, polished, or edge-worked beyond simple cutting to shape. The presence of the wire mesh ensures that the glass remains in the frame even when cracked, which is why it is specifically called out in subheading 7003.20.

Codes often confused with 7003.20
Common mistake. Wired glass is frequently misclassified under HS code 7005, which covers float glass and surface ground or polished glass. However, 7005 specifically excludes glass that is wired. Another common error is classifying it under 7007, which covers safety glass consisting of toughened (tempered) or laminated glass. While wired glass is often used for safety purposes, it is technically distinct from tempered or laminated glass in the Harmonized System and must remain in 7003.20 if it is cast or rolled and contains wire.
Top exporters and importers of HS 700320 (the code used for wired glass sheets), 2025
In 2025, the largest exporter of HS 700320 (the code used for wired glass sheets) in UN Comtrade data was Germany, with 27% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 11% of world imports.

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).
