Iron or steel, structures and parts thereof, doors, windows and their frames and thresholds for doors.
Classification of steel windows under HS 7308.30
Steel windows and their frames are classified under HS code 7308.30. This classification falls under Chapter 73, which covers articles of iron or steel. Specifically, heading 7308 applies to structures and parts of structures, such as bridges, lock-gates, towers, and pillars. While many steel items are classified by their specific form (like bars or sheets), windows are considered functional parts of a building structure. Subheading 7308.30 is the specific international designation for doors, windows, and their frames, as well as thresholds for doors. The classification remains consistent whether the windows are for industrial, commercial, or residential use. It is important to note that for a product to fall under this code, the primary material must be iron or steel. The classification is determined by the essential character of the item as a structural component designed for permanent installation in a building or similar structure.

Codes often confused with 7308.30
Common mistake. Steel windows are often misclassified under 7326.90, which is a residual category for other articles of iron or steel. However, because 7308.30 specifically mentions windows, it takes precedence according to GRI 3(a). Another common error is using 7610.10, which is reserved for aluminum windows. Importers must also distinguish between raw steel profiles (7216) and finished window frames (7308.30); once the profile is cut to size and joined into a frame, it must be moved to 7308.30.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
