Duty Rates
General (Column 1 - MFN)
5.5%
This is an ad valorem duty, meaning the import duty is calculated as a percentage (5.5%) of the declared value of the imported goods.
Special Trade Agreement Rates
The following countries and trade agreements qualify for reduced or eliminated tariffs:
GSP (Generalized System of Preferences)
Australia FTA
Bahrain FTA
Chile FTA
Colombia TPA
AGOA (African Growth and Opportunity Act)
Caribbean Basin Initiative
Israel FTA
Jordan FTA
Korea-U.S. (KORUS) FTA
Morocco FTA
Oman FTA
CAFTA-DR (Central America)
Panama TPA
Peru TPA
AGOA Least-Developed Beneficiary
Singapore FTA
Rate: Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)
Column 2 Rate (Non-Tariff Treaty Countries)
This rate applies to countries without normal trade relations (most-favored-nation status) with the United States:
35%
Column 2 rates are substantially higher than Column 1 rates and are rarely applied in modern international trade due to most-favored-nation agreements.
What HTS 2846.10.00 Covers
This code covers chemical compounds of cerium, whether inorganic or organic. Typical products are cerium oxide (ceria), cerium carbonate, cerium chloride, cerium nitrate and cerium hydroxide. It sits within heading 2846, which covers compounds of rare-earth metals, yttrium and scandium.
Notes for Importers
Cerium oxide polishing powders for glass, optics and semiconductor work are the most common import, along with cerium salts for catalysts and pigments. Compounds of other rare earths, or mixed rare-earth compounds where cerium is not the basis, fall in 2846.90 instead. Cerium metal itself belongs in 2805.30, and finished polishing preparations with added ingredients may classify in chapter 34.

Frequently Asked Questions
Is cerium oxide polishing powder classified under 2846.10.00?
Pure or substantially pure cerium oxide powder generally is. However, if it is put up as a prepared polishing composition with binders or other additives, it may instead classify as a polishing preparation in chapter 34.
Does this code cover mixed rare-earth compounds that contain cerium?
Only if cerium is the defining component. Mixtures of rare-earth compounds where another element predominates, or general mixed rare-earth compounds, are classified under 2846.90.
Where does cerium metal classify?
Cerium in metallic form, including mischmetal, is classified under 2805.30.00, not here. This code is strictly for chemical compounds of cerium.
What is the HTS code 2846.10.00 used for?
HTS code 2846.10.00 is the harmonized tariff schedule code for Cerium compounds. This code is used to classify and identify this product type for customs clearance, duty calculation, and trade statistics.
What is the Column 2 rate for HTS 2846.10.00?
The Column 2 rate is the tariff duty rate applicable to goods from countries that do not have normal trade relations with the United States. This rate is typically higher than Column 1 (Most Favored Nation) rates and is rarely used in modern trade due to most-favored-nation agreements.
Do I need a customs broker to import goods classified under HTS 2846.10.00?
While not always required, using a licensed customs broker is highly recommended for most imports. A customs broker can help ensure proper HTS classification, prepare customs documentation, pay duties correctly, and avoid delays or penalties. Your broker should be familiar with Chemical Products products.
Which countries receive special tariff rates for HTS 2846.10.00?
Multiple free trade agreements and trade preference programs provide reduced or free tariffs for eligible HTS classifications. Common programs include USMCA (Canada, Mexico), various bilateral FTAs (Korea, Australia, Singapore), GSP for developing countries, and AGOA for eligible African nations. Check the special rates section on this page.
How does HTS code 2846.10.00 affect my import costs?
The HTS code determines the applicable duty rate (either free or a percentage/specific amount), whether your product qualifies for trade agreement benefits, any quota restrictions, and special documentation requirements. Proper classification directly impacts your import expenses, so verify the correct code with your supplier or a customs professional.
