No — both straight-blade bulldozers and angledozers (whose blades pivot horizontally to cast material laterally) are classified together under this heading. The blade geometry does not create a separate classification. The distinction that matters for classification is between bulldozers/angledozers and graders or scrapers, which are separately classified based on their earthmoving function.

Bulldozers imported from certain countries may be subject to Section 301 tariffs or, depending on the specific HTS subheading and origin, Section 232 measures. Importers should conduct a full tariff analysis — including checking for any active antidumping or countervailing duty orders on construction equipment — with a licensed customs broker before finalizing purchase agreements, as these measures can materially affect landed cost.
