HTS heading 7507 is a broad product category for nickel tubes, pipes, and tube or pipe fittings. It groups together hollow products used to carry, contain, or connect fluids, gases, or other materials, including items such as couplings, elbows, and sleeves. The heading covers both the tube or pipe itself and certain fittings designed to join or redirect it.
To reach the correct 8-digit HTSUS code, first confirm that the product is made principally of nickel and belongs in this heading rather than a heading for another base metal or a specialized finished article. Then narrow the classification using the relevant tariff descriptions and subheadings, which may distinguish the product by form or type, such as tube or pipe versus a fitting, and by material, construction, or other stated characteristics. Review the complete 8-digit description and any applicable legal notes, rather than relying on the heading title alone.
What to check
- Confirm the item’s primary material, including whether it is nickel, a nickel alloy, or another metal, and keep specifications or mill documentation available.
- Determine whether the item is a tube, pipe, or fitting; identify the fitting type, such as a coupling, elbow, or sleeve, when applicable.
- Check the product’s construction and physical characteristics, including seamless or welded construction, dimensions, cross-sectional shape, and intended connection method, if the subheadings ask for them.
- Compare the full 8-digit HTSUS descriptions and relevant chapter or section notes; do not select a code from a shortened heading description alone.
- Use product drawings, catalogs, invoices, and technical data to support the classification, and seek a customs broker or binding ruling when the characteristics or heading choice are uncertain.

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.
