7308.20.00 - Towers and lattice masts

HTS Code 7308.20.00 specifically encompasses towers and lattice masts constructed from iron or steel. These structures are designed for elevated purposes, such as supporting telecommunications equipment, power lines, or observation platforms. The defining characteristic is their open-frame or lattice construction, which provides strength and stability while minimizing material usage and wind resistance.

This category is distinct from its sibling headings. Unlike 7308.10.00.00, which covers bridges and bridge sections for spanning openings, or 7308.30.00.00, which pertains to doors, windows, and their associated frames, 7308.20.00.00 focuses exclusively on vertical support structures. It also differs from 7308.40.00.00, which relates to temporary structural equipment like scaffolding, and the residual category 7308.90.00.00, which covers other iron and steel structural articles.

The subcategories within 7308.20.00.00 provide further granularity. 7308.20.00.30 and 7308.20.00.35 differentiate based on whether the towers are tubular and, in the latter's case, specifically designed for wind turbine applications. The remaining items fall under 7308.20.00.90, capturing all other types of towers and lattice masts not otherwise specified by the preceding subheadings.
