Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from artificial uranium or enriched
Artificial uranium compounds, including those from reprocessed fuel, classify under subheading for artificial isotopes regardless of natural origin processing
If in form of natural uranium metal or alloys
Pure natural uranium metal or alloys shift to the specific subheading before 'other uranium compounds'
If mixed with significant non-radioactive carriers exceeding regulatory thresholds
Mixtures with specific radioactivity below 74 Bq/g treated as chemical preparations rather than defined radioactive compounds
