HTS heading 8606 is a 4-digit product category for railway or tramway freight cars that are not self-propelled. In plain language, it generally covers freight-carrying rail vehicles that must be pulled or pushed by a locomotive or another powered rail vehicle, rather than moving under their own power. The category can include different freight-car designs and equipment, subject to the HTS notes and exclusions.
To reach the correct 8-digit HTS code, start with the heading and then follow the more detailed subheadings. The tariff schedule commonly separates products by the car’s construction or intended type, such as whether it is made for a particular freight function or has particular equipment or features. Review the legal text, product descriptions, and any applicable statistical suffix, and classify the complete imported article as presented at entry. If the design is unusual or the description is unclear, a customs broker or binding-ruling process may be appropriate.
What to check
- Confirm that the article is a freight car for railway or tramway use and is not self-propelled.
- Document the car’s construction, capacity, configuration, loading method, and principal intended use.
- Read every 6-digit and 8-digit subheading under heading 8606; do not choose based only on a similar commercial product name.
- Check the HTS legal notes, exclusions, and any statistical suffix instructions before finalizing the code.
- Ask a customs broker or request a binding classification ruling when the car has unusual equipment, multiple functions, or an uncertain tariff description.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
