Last updated: August 2026 dataMarine propellers and their individual blades — whether fixed-pitch, controllable-pitch, or azimuth-type — are classified under heading 8487, with the US schedule distinguishing copper-alloy propellers (8487100040) from those made of other materials (8487100080). Nickel-aluminum bronze is the dominant alloy in commercial and naval applications, making material composition a key classification and specification variable. Taiwan leads US imports under this heading, with the United Kingdom and Finland also among the top suppliers — the latter two reflecting European expertise in high-performance propulsion systems for commercial shipping and offshore vessels.

205 import shipments a month
Propellers and blades made of copper alloys — most commonly nickel-aluminum bronze or manganese bronze — are classified under 8487100040. Those made of stainless steel, composite materials, or other non-copper metals fall under 8487100080. The alloy composition should be confirmed by a material certificate or mill test report, as CBP may request metallurgical documentation for high-value marine propulsion components.
Importers should conduct a current AD/CVD order search through the International Trade Administration's Enforcement and Compliance database before entry, as trade-remedy coverage can change. The material and country of origin are both relevant variables, since orders are product- and country-specific. A licensed customs broker can assist in determining whether a specific shipment falls within the scope of any active order.
