HTS heading 2517 is a broad product category for certain stone, mineral aggregate, and related materials used mainly in construction and infrastructure. It groups pebbles, gravel, and broken or crushed stone used for concrete aggregate, road surfacing, or railway and other ballast; shingle and flint; certain macadam made with industrial waste; tarred macadam; and granules, chippings, or powder made from stones covered by headings 2515 or 2516. Some products may be heat-treated and still remain within the heading, depending on the applicable subheading language.
The 4-digit heading is only the starting point. To reach the correct 8-digit HTSUS classification, identify the material and product form, then follow the more specific subheadings and statistical suffixes. The relevant distinctions may include the type of stone, whether the goods are natural aggregate or macadam, whether they are granules, chippings, or powder, and whether the material comes from heading 2515 or 2516. Classification can depend on the product’s objective characteristics and intended use; when the wording is unclear, a customs broker or binding ruling may be appropriate.
What to check
- Describe the goods precisely: identify the mineral or stone, particle size or form, processing, and whether the product is aggregate, ballast, macadam, chippings, or powder.
- Check whether the material is specifically tied to stone from heading 2515 or 2516, rather than treating all crushed stone as interchangeable.
- Review every subheading under 2517 and compare its wording with the product’s composition and physical condition, including any heat treatment.
- Use product specifications, laboratory or supplier documentation, photographs, and technical data to support the classification and intended use.
- Confirm the complete 8-digit HTSUS code in the current official tariff and seek customs-broker advice or a binding ruling if multiple subheadings could apply.
HTS heading 2517 summary
Pebbles is a 4-digit product category containing 3 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
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.

How do I choose the right code within this category?
