Iron & Steel Towers and Lattice Masts

Yes. Utility-scale wind towers have been the subject of antidumping and countervailing duty orders covering certain countries of origin. Importers should check the current scope of any active orders with CBP or the International Trade Commission before sourcing, as scope rulings can affect whether a specific tower design and origin combination is covered.

Tubular towers are hollow cylindrical or conical steel sections stacked to form a self-supporting column, as used in wind turbines and some telecom applications. Lattice masts are open-frame structures assembled from angle, bar, or tube members. The US schedule provides separate lines for tubular towers (including wind turbine towers) and a residual line for other towers and lattice masts, so the structural form of the article determines the correct 10-digit code.
