HTS heading 7102 is a 4-digit product category for diamonds that are not mounted or set in jewelry or another article. It can include diamonds in different physical conditions, from unworked or rough stones to stones that have been cut, polished, or otherwise worked, as long as they are not mounted or set. The heading can cover both natural and synthetic diamonds, subject to the detailed tariff provisions.
To select the specific 8-digit HTSUS code, move through the subheadings and statistical subdivisions in order. The distinctions commonly depend on factors such as whether the diamond is natural or synthetic, whether it is for industrial or nonindustrial use, and whether it is unworked, sawn, cut, polished, or otherwise worked. The product’s physical characteristics and stated use must match the wording and legal notes for the applicable subdivision; do not choose a code based only on a commercial description such as “diamond stone.”
What to check
- Confirm that the diamond is not mounted or set; if it is attached to jewelry or another article, examine the classification for that finished article instead.
- Document whether the stone is natural or synthetic, and retain reliable evidence such as a laboratory report, supplier specification, or production record.
- Describe the stone’s condition precisely: rough or unworked, sawn, cut, polished, drilled, or otherwise worked, and check the tariff definitions for those terms.
- Check whether the tariff distinguishes industrial-use diamonds from nonindustrial diamonds, and make sure the claimed use is supported by the product and transaction records.
- Read every relevant subheading, legal note, and statistical description before selecting the 8-digit code; ask a customs broker or request a formal ruling when the facts are 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.
