HTS heading 2506 is a four-digit product category for quartz, other than natural sands, and quartzite. It can include these materials in a rough form or merely cut by sawing or another method into rectangular or square blocks or slabs. The heading is about the material and its basic form; it does not automatically cover every quartz-containing manufactured product.
To choose the specific eight-digit HTS code, start with the heading and read the subordinate provisions beneath it. The tariff schedule usually narrows the category by distinctions such as whether the product is quartz or quartzite and by the relevant material or form. The final digits identify the more specific statistical classification, so the product’s composition, processing, dimensions, and presentation must match the wording of the selected provision.
What to check
- Confirm that the merchandise is quartz or quartzite, not natural sand or a finished product made from quartz.
- Determine whether the item is a rough piece, a block, or a rectangular or square slab produced by sawing or another basic cutting process.
- Check the product’s technical description, mineral composition, dimensions, and processing history against every applicable subheading description.
- Read the complete eight-digit provision and any related legal notes, exclusions, and statistical suffix instructions in the current HTSUS.
- If the product is polished, shaped, assembled, engineered, or otherwise substantially manufactured, obtain a customs-broker or classification specialist review before filing.
HTS heading 2506 summary
Quartz is a 4-digit product category containing 2 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?
