HS-4 · Heading
2846 — Compounds, inorganic or organic, of rare-earth metals; of yttrium or of scandium or of mixtures of these metals
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2846 when importing compounds of rare-earth metals, such as cerium compounds or mixtures that include yttrium and scandium. For example, if you're shipping a batch of cerium oxide used in glass polishing, this is the correct heading.
To differentiate between the HS-6 lines, note that 284610 specifically covers cerium compounds, while 284690 includes all other rare-earth metal compounds, including those of yttrium and scandium. If your product contains cerium, use 284610; otherwise, opt for 284690.
When assessing your shipment, consider the specific composition of your product. If your mixture contains cerium along with other rare-earth elements, it still falls under 284610. However, if it only contains yttrium or scandium without cerium, then 284690 is the appropriate code.
