Last updated: September 2026 dataCerium compounds — including cerium oxides used as polishing agents for glass and semiconductors, and other cerium salts used in catalysts and UV-absorbing coatings — are commercially significant rare-earth derivatives with broad industrial applications. The US tariff schedule distinguishes cerium oxides (2846100010) from other cerium compounds (2846100050), with a legacy parent line (2846100000) also present. Japan leads US imports under this heading, with China and Austria also notable sources — a supplier mix that reflects both downstream processing capacity and proximity to rare-earth raw material supply chains.

HTS 2846100010 covers cerium oxides specifically (primarily CeO₂ and Ce₂O₃), while 2846100050 captures all other cerium compounds such as cerium nitrate, cerium acetate, and cerium carbonate. The distinction matters because polishing-grade cerium oxide is the dominant commercial form and may face different trade remedy exposure than other cerium salts.
Cerium compounds imported from China may be subject to Section 301 tariffs applicable to Chinese-origin chemical products. Importers should verify the current Section 301 list coverage for their specific 10-digit HTS line and consult a licensed customs broker, as applicability and rates can change.
