Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing depleted uranium instead of or with thorium
Mixtures or compounds with depleted U235 are classified separately under the uranium subheading.
If in retail packaging as lab reagent or mixture not chemically defined
Non-chemically pure preparations or mixtures fall into Chapter 38 as chemical products not elsewhere specified.
If for natural uranium or its compounds, not thorium-specific
Uranium compounds have their own preceding subheading in 2844.

Import Tips & Compliance
• Obtain NRC or agreement state license prior to import due to thorium's radioactive nature; submit Form 741 for reporting
• Include detailed chemical composition, activity levels, and safety data sheets in documentation to avoid customs delays
• Verify exemption status for low-specific-activity thorium; common pitfall is failing radiation transport regulations under DOT
