Product classification
HS code for Lattice masts: 7308.20
Iron or steel, structures and parts thereof, towers and lattice masts.
Classification of lattice masts under HS 7308.20
Lattice masts made of iron or steel are classified under HS code 7308.20. This classification falls under Chapter 73, which covers articles of iron or steel, and heading 7308, which specifically addresses structures and parts of structures. Subheading 7308.20 is explicitly dedicated to towers and lattice masts. A lattice mast is defined by its open-work construction, usually consisting of vertical members connected by diagonal and horizontal bracing. The classification is based on the material (iron or steel) and the structural nature of the item. According to GRI 2(a), even if the masts are imported in a disassembled or 'knocked down' state (which is common for ease of transport), they are classified as the finished structure because they have the essential character of the complete article. The classification remains the same whether the mast is intended for supporting electrical power lines, radio antennae, or telecommunications equipment, as the heading is defined by the physical form of the structure rather than its specific end-use.

Codes often confused with 7308.20
Common mistake. Lattice masts are sometimes misclassified under HS code 8517.70 as parts of telecommunication apparatus. However, Section XV Note 1(f) and Section XVI Note 1(l) clarify that structures of base metal are excluded from those sections and must be classified in their respective metal chapters (Chapter 73). Another error is using 7304, which covers tubes and pipes; while masts may be made of tubes, once they are fabricated into a lattice structure, they must be classified under 7308.
Top exporters and importers of HS 730820 (the code used for lattice masts), 2025
In 2025, the largest exporter of HS 730820 (the code used for lattice masts) in UN Comtrade data was China, with 19% of world exports; the largest importer in UN Comtrade data was the United States, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
