HTS heading 7104 is a four-digit category for synthetic or reconstructed precious and semiprecious stones. These are man-made or reconstructed versions of stones, such as laboratory-produced stones, when they are loose rather than permanently mounted, set, or strung. The heading can also cover ungraded stones temporarily strung only to make transport easier.
To reach the correct eight-digit HTSUS code, first identify the stone’s material or type. Then check the relevant distinctions in the tariff schedule, such as whether the stone is synthetic or reconstructed, graded or ungraded, and worked or unworked. Stones already mounted or set in jewelry or another article may belong elsewhere, so classification depends on the product as imported and may require customs-broker review.
What to check
- Confirm that the stone is synthetic or reconstructed, rather than natural, imitation, or merely treated natural stone.
- Identify the exact material or stone type from supplier specifications, laboratory reports, and product records.
- Check whether the stones are cut, polished, drilled, or otherwise worked, and whether they are graded.
- Verify that any stringing is only temporary for transport and that the stones are not mounted, set, or made into finished jewelry.
- Read the current HTSUS subheadings and statistical suffixes, and obtain broker or ruling guidance if the product’s composition or presentation is unclear.

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.
