Products classified under Tariff item 7308.20
Broadcast Tower Tubular Diaphragm
Ring-shaped tubular steel diaphragms providing horizontal stiffening in FM broadcast lattice towers. These are components of a lattice mast, designed for bolted assembly, and fall under the tariff item for towers and lattice masts as parts thereof.
7308.20.00Broadcast TV Lattice Tower
A heavy-duty steel lattice tower designed to support multiple TV transmission antennas and side-mount equipment. Its open lattice structure and height make it a classic example of a tower or lattice mast of iron or steel, used in broadcasting applications.
7308.20.00Cell Tower Tubular Redundancy Brace
Secondary cylindrical steel bracing tubes providing redundancy in multi-legged cell tower masts. These lightweight, galvanized components are designed for wind resistance and are part of a lattice mast, fitting the tariff item for towers and lattice masts.
7308.20.00Galvanized Steel Cell Tower
A self-supporting galvanized steel tower assembled from bolted sections, designed for mounting telecommunications antennas. This is a complete tower structure of iron or steel, fitting squarely under the tariff item for towers and lattice masts.
7308.20.00Galvanized Steel Tubular Tower Leg
A cylindrical, tapered steel tube used as a primary leg component in lattice mast towers for telecommunications. Hot-dip galvanized and prepared for structural bolting, this is a component of a lattice mast, falling under the tariff item for towers and lattice masts.
7308.20.00Guyed Mast Tubular Base Section
A wide-base cylindrical steel tube forming the foundation section of guyed radio transmission masts. With heavy-wall construction and flange connections, this is a component of a lattice mast, fitting the tariff item for towers and lattice masts.
7308.20.00Guyed Steel Radio Tower
A guyed steel lattice mast built from welded steel angles, supported by guy wires and used for FM radio broadcasting antennas. Its lattice construction and use as a mast for communication make it a clear fit for the tariff item on towers and lattice masts.
7308.20.00Lattice Steel Transmission Tower
A lattice mast constructed from angled steel sections, designed to support high-voltage electrical transmission lines. This is a tower of iron or steel used in power grid infrastructure, falling directly under the tariff item for towers and lattice masts.
7308.20.00Microwave Relay Lattice Mast
A steel lattice structure tower used for mounting microwave dishes in point-to-point communication links. Hot-dip galvanized for corrosion resistance, this is a lattice mast of iron or steel for telecom relay stations, fitting the tariff item for towers and lattice masts.
7308.20.00Microwave Tower Tapered Pole Section
A tapered tubular steel section for microwave communication tower poles in lattice configuration, including splice plates for field assembly. This is a sectional component of a lattice mast, falling under the tariff item for towers and lattice masts.
7308.20.00Monopole Lattice Hybrid Tower Shaft
A hybrid tubular steel shaft combining monopole and lattice features for cellular towers, tapered with lattice bracing points. This is a component of a tower or lattice mast, fitting the tariff item for towers and lattice masts.
7308.20.00Observation Lookout Tower
A prefabricated steel lattice tower providing elevated viewpoints for fire watch, wildlife observation, or tourism. With stairs or ladder access and a powder-coated finish, this is a tower of iron or steel, fitting the tariff item for towers and lattice masts.
7308.20.00Self-Support Steel Fire Tower
A lattice tower constructed from high-strength steel for forest fire lookout stations, with an optional enclosed cab. This tower of iron or steel is designed for public safety use and falls under the tariff item for towers and lattice masts.
7308.20.00Solar Farm Support Tower
A steel lattice tower for elevated solar panel arrays in utility-scale photovoltaic installations. Distinct from panel mounting racks, this tower of iron or steel is designed for high wind zones and fits the tariff item for towers and lattice masts.
7308.20.00Wind Monitoring Tower
A lattice steel tower fitted with anemometers and sensors for meteorological wind data collection at potential wind farm sites. This tower of steel is separate from power generation equipment and falls under the tariff item for towers and lattice masts.
