Subheadings
Products classified under HTS 7308.20.00
Galvanized Steel Cell Tower
A tall, self-supporting tower made of galvanized steel sections bolted together, designed for mounting telecommunications antennas and equipment. It falls under HTS 7308.20.00 as a tower structure of iron or steel used in communication infrastructure. The lattice design provides stability and wind resistance.
Microwave Relay Lattice Mast
Steel lattice structure tower for mounting microwave dishes in point-to-point communication links. Falls under HTS 7308.20.00 as a lattice mast of iron or steel for telecom relay stations. Hot-dip galvanized for corrosion resistance in remote locations.
Wind Monitoring Tower
Lattice steel tower fitted with anemometers and sensors for meteorological wind data collection at potential wind farm sites. Classified in HTS 7308.20.00 as a tower structure of steel, separate from power generation equipment. Portable design for temporary installation.
Broadcast TV Lattice Tower
Heavy-duty steel lattice mast supporting multiple TV transmission antennas and side-mount equipment. HTS 7308.20.00 classification for towers of iron or steel in broadcasting applications. Features ice shield and fall arrest systems.
Self-Support Steel Fire Tower
Lattice tower constructed from high-strength steel for forest fire lookout stations with enclosed cab option. Falls under HTS 7308.20.00 as a tower structure of iron or steel for public safety use. Wind load rated to 120 mph.
Solar Farm Support Tower
Steel lattice tower for elevated solar panel arrays in utility-scale photovoltaic installations. Classified HTS 7308.20.00 as tower of iron or steel, distinct from panel mounting racks. Designed for high wind zones.
Lattice Steel Transmission Tower
A lattice mast constructed from angled steel sections for supporting high-voltage electrical transmission lines. Classified under HTS 7308.20.00 due to its tower design and use in power grid infrastructure of iron or steel. Engineered for heavy load-bearing and extreme weather conditions.
