HTS heading 7306 is a broad product category for certain tubes, pipes, and hollow profiles made of iron or steel. It generally covers products formed by joining or closing material, such as open-seamed, welded, riveted, or similarly closed items, rather than treating every tube or pipe as the same product. The heading can include different shapes and uses, but the exact scope depends on the tariff text and any applicable section or chapter notes.
To narrow heading 7306 to an 8-digit HTS code, start with the product’s objective characteristics. Check the metal type and grade, whether it is carbon steel, stainless steel, or another iron-or-steel material; how it was made, such as welded or otherwise closed; the cross-sectional shape; dimensions and wall thickness; and whether it has special features or uses identified by the tariff schedule. The 8-digit code is selected by following the progressively narrower descriptions under heading 7306—not simply by choosing the code that sounds most like the product.
What to check
- Obtain the manufacturer’s specification sheet, including material grade, manufacturing method, dimensions, and wall thickness.
- Confirm whether the item is a tube, pipe, or hollow profile and identify its cross-sectional shape and exact measurements.
- Check the relevant 7306 subheadings for distinctions based on stainless versus other steel, welded or other construction, and product dimensions or features.
- Review the HTS section and chapter notes, legal notes, and any exclusions before finalizing the 8-digit code.
- Compare the proposed classification with official customs rulings or ask a qualified customs broker when the construction, material, or intended use creates uncertainty.

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.
