HTS heading 2846 groups chemical compounds made with rare-earth metals, yttrium, scandium, or mixtures of those metals. It covers both inorganic compounds and organic compounds, rather than the metals in their elemental form. Examples may include compounds of cerium, lanthanum, neodymium, yttrium, or scandium, but the product’s actual chemical identity must be confirmed.
Heading 2846 is only a 4-digit category. To select the complete 8-digit HTSUS code, narrow the product by the legally relevant description at the more detailed tariff levels—usually the specific metal or mixture and the type of compound. Review the chapter notes, heading text, subheadings, and any applicable statistical suffix descriptions; classification can also depend on composition, chemical form, and whether the product is a mixture or preparation.
What to check
- Obtain the product’s chemical name, formula, composition, and technical specification from the manufacturer or laboratory documentation.
- Confirm whether the item is a compound of a rare-earth metal, yttrium, scandium, or a mixture, rather than an elemental metal, alloy, ore, or unrelated preparation.
- Compare the product’s exact compound and metal identity with the 6-digit subheading and 8-digit statistical suffix descriptions in the current HTSUS.
- Check relevant Section VI and Chapter 28 notes, including rules that may exclude mixtures, solutions, or specially described preparations from a particular provision.
- If the chemical description does not clearly match one provision, seek a binding classification ruling or advice from a qualified customs broker or trade professional.
HTS heading 2846 summary
Compounds is a 4-digit product category containing 1 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.

Common questions
What products fall under HTS heading 2846?
Compounds, inorganic or organic, of rare-earth metals, of yttrium or of scandium, or of mixtures of these metals. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
