HTS heading 4406 is a four-digit product category for railway or tramway sleepers, also called wooden cross-ties. These are structural wood members installed across or alongside rail lines to support and hold the rails in position. The heading groups qualifying sleepers made of wood; it is not a general category for every wooden beam, plank, or construction product.
To choose an eight-digit HTSUS code, start with the product’s actual design and intended use, then follow the subheadings and statistical subdivisions under heading 4406. The available subdivisions commonly distinguish the sleeper by characteristics such as the type or condition of wood and other product specifications. Confirm the exact wording in the current HTSUS, and do not assume that a general-purpose timber product belongs here merely because it could be used near a railway.
What to check
- Verify that the item is designed and marketed as a railway or tramway sleeper, rather than as ordinary lumber, a beam, or a finished rail component.
- Identify the wood species or other material description, and check whether the tariff text distinguishes it from other wood types or conditions.
- Check the product’s physical form, treatment, and degree of processing against the relevant subheading notes and statistical descriptions.
- Read all eight digits of the candidate HTSUS code; the four-digit heading alone is not sufficient for entry, classification, or duty review.
- Keep product specifications, invoices, drawings, and photos that support the intended use and material, and seek a customs broker or binding classification advice when the distinctions are unclear.

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.
