8487.10.00.40 - Of copper

This HTS category, 8487.10.00.40, specifically covers parts for ships' or boats' propellers that are made of copper. This includes components such as propeller blades, hubs, or other related elements designed for marine propulsion systems, where copper is the primary material of construction. The defining characteristic for classification under this code is the material composition – only propeller parts manufactured from copper will fall into this specific subcategory.

This classification is distinct from its sibling category, 8487.10.00.80, which is designated for "Other" ships' or boats' propeller parts. While both categories concern components for marine propellers, 8487.10.00.40 is narrowly focused on copper, whereas the "Other" category would encompass propeller parts made from any other material, such as aluminum alloys, stainless steel, or composite materials. This distinction allows for precise tariff application based on the dominant material used in the manufacture of the propeller part.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the classification hinges entirely on the identification of a ships' or boats' propeller part that is made of copper. It is crucial to verify the material composition to ensure accurate classification and avoid misdeclaration.
