About heading 7308
Structures (excluding prefabricated buildings of heading 9406) and parts of structures (for example, bridges and bridge sections, lock gates, towers, lattice masts, roofs, roofing frameworks, doors and windows and their frames and thresholds for doors, shutters, balustrades, pillars and columns) of iron or steel; plates, rods, angles, shapes, sections, tubes and the like, prepared for use in structures, of iron or steel
Heading 7308 covers iron or steel structures and parts of structures that are made up and ready to install, such as bridges, towers, doors and window frames, and scaffolding equipment. It also covers plates, rods, angles, shapes and tubes that have been prepared for use in structures. The heading is split first by article type into bridges, towers and lattice masts, doors and windows, scaffolding equipment, and a residual Other group, which is then split by material and by specific article.
