8607.21.10.00 - For vehicles of heading 8605 or 8606 🖩

This HTS code, 8607.21.10.00, specifically classifies components of air braking systems designed for use with railway or tramway vehicles classified under headings 8605 (special purpose railway or tramway coaches, not self-propelled) or 8606 (railway or tramway maintenance or construction vehicles). This includes a wide array of parts that are integral to the operation of pneumatic braking mechanisms on these specific types of rolling stock. Examples can include, but are not limited to, air brake valves, cylinders, actuators, compressors (when specifically designed and solely intended for the air brake system), brake pipes, and associated fittings and couplings.

This category is distinguished from its sibling, 8607.21.50.00, which covers "Other" air brake parts. While 8607.21.10.00 is intended for specific components directly related to the air braking function on vehicles of headings 8605 or 8606, the "Other" category would encompass any remaining parts of air braking systems not precisely fitting the more defined scope of 8607.21.10.00, or parts of air braking systems for locomotives or other rolling stock not falling under 8605 or 8606.

As this HTS code represents a leaf node within the tariff schedule, there are no further subcategories. Classification within this specific code therefore hinges on meeting the criteria of being a part of an air brake system and its intended application for vehicles classified under headings 8605 or 8606. Proper identification of the specific function and origin of the component, along with the type of rolling stock it is designed for, is crucial for accurate classification.
