Uranium Tetrafluoride (UF4)

Uranium tetrafluoride (UF4), also known as green salt, is a radioactive compound of depleted uranium used as an intermediate in nuclear fuel processing to produce uranium hexafluoride for enrichment. It falls under HTS 2844.30.20.20 as a fluoride compound of uranium depleted in U235, explicitly covered in this subheading for uranium fluorides.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2844.30.10.00Higher: 15.5% vs Free

If compounds of thorium rather than uranium

Thorium fluorides are classified separately from uranium compounds in the preceding subheading.

2844Same rate: Free

If in the form of mixtures or residues rather than pure fluorides

Residues containing uranium fluorides fall under the broader mixtures and residues heading.

2845.10.00.00Higher: 35% vs Free

If the isotope mixture is enriched in U235 rather than depleted

Enriched uranium and its compounds are classified in Chapter 2845, distinct from depleted uranium products.

Import Tips & Compliance

Obtain prior NRC authorization under 10 CFR Part 110 for export/import of uranium compounds; unlicensed import is prohibited

Provide detailed radiation safety data, including specific activity levels, and ensure packaging meets UN 2977 standards for radioactive material

Avoid misclassification by verifying depletion status (U235 <0.711%); full U235 assay reports prevent customs delays
