HTS heading 7608 is a four-digit product category for aluminum tubes and pipes. It generally covers hollow aluminum products used to convey or contain liquids, gases, or other materials, including products described commercially as tubing or pipe. The heading is broader than a final import code and does not by itself determine duty treatment.
To reach the specific eight-digit HTSUS code, first confirm that the item belongs in heading 7608 rather than another heading for aluminum products, fittings, or fabricated articles. Then use the applicable subheadings, which commonly distinguish factors such as whether the aluminum is non-alloyed or an aluminum alloy and whether the tube or pipe is seamless or another type. The product’s technical specifications and the HTSUS notes control, not just its sales description.
What to check
- Confirm the item is a tube or pipe itself, rather than a tube fitting, assembled component, or finished article incorporating tubing.
- Obtain the aluminum composition and alloy designation from the mill certificate, product specification, or supplier documentation.
- Check whether the product is seamless, welded, or another construction type, and verify how the HTSUS describes that distinction.
- Record key physical details such as outside diameter, wall thickness, shape, and intended use; use them to test the classification rather than assuming commercial terminology is decisive.
- Compare the current HTSUS heading notes, subheading descriptions, and any applicable classification rulings; ask a customs broker or classification specialist when the specifications do not clearly match one code.

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.
