Uranium Tetrafluoride Powder (UF4)
Uranium tetrafluoride (UF4), also known as green salt, is a key intermediate compound produced during the conversion of natural uranium ore into nuclear fuel or enrichment feed. As a chemically defined compound of natural uranium, it is classified under tariff item 2844.10.00, which covers natural uranium and its compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the UF4 contains enriched uranium (U-235 above 0.711%)
Enriched uranium compounds fall under a different tariff item for fissile isotopes.
If the UF4 contains depleted uranium (U-235 below 0.711%)
Depleted uranium compounds are classified separately from natural uranium.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify that the UF4 is derived from natural uranium (not enriched or depleted beyond natural isotopic levels) to ensure correct classification under 2844.10.00
• Obtain a valid import permit from the Canadian Nuclear Safety Commission (CNSC) before shipment, as uranium compounds are controlled substances
• Declare the exact isotopic composition and chemical purity on customs documents to avoid delays
