8487.90.00 - Other

HTS code 8487.90.00 encompasses a broad category of "other" machinery parts that are not specifically enumerated in other headings within Chapter 84. These are mechanical components designed for use with machinery but do not possess electrical features such as connectors, insulators, coils, or contacts. Crucially, this classification applies to parts that are not specifically provided for elsewhere in Chapter 84, nor are they classifiable under other chapters of the Harmonized Tariff Schedule.

This heading is distinguished from its sibling, 8487.10.00, which specifically covers ships' or boats' propellers and their blades. While both are parts of machinery, 8487.90.00 is a residual category for all other machinery parts that meet the general criteria of being mechanical, non-electrical, and not otherwise specified. The defining characteristic is the absence of electrical components and a lack of more specific tariff treatment.

Within 8487.90.00, further subdivisions exist to provide more granular classification. The subcategory 8487.90.00.40 specifically addresses oil seals, excluding those classified under Chapter 40, which deals with rubber and plastics. The remaining items that do not fit this specific oil seal designation fall under the residual subcategory 8487.90.00.80, ensuring that all "other" machinery parts not otherwise classified are appropriately categorized.
