Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If de-fueled and treated as scrap metal
Empty zirconium tubes without radioactivity revert to tubes/pipes classification in Chapter 73.
If for natural uranium or plutonium compounds therein
Extracted fissile compounds may classify under specific element subheadings if separated.

Import Tips & Compliance
• Secure bilateral agreements under NPT for fissile material transfers; file with IAEA
• Ensure cask certifications match fuel geometry to avoid transport violations
• Document burn-up levels accurately to classify correctly and prevent mislabeling fines

Uranium Dioxide Spent Fuel Rods
These are irradiated uranium dioxide (UO2) fuel rods extracted from nuclear reactors after use, containing fission products and actinides. Classified under HTS 2844.50.00.00 as spent (irradiated) fuel elements due to their high specific radioactivity from reactor exposure. They require specialized handling for reprocessing or disposal.
MOX Spent Fuel Elements
Mixed oxide (MOX) fuel elements, combining plutonium and uranium oxides, irradiated in reactors like those at La Hague. HTS 2844.50.00.00 covers these as spent cartridges due to their radioactive content exceeding 74 Bq/g. Used in advanced reactor cycles for plutonium recycling.
BWR Spent Fuel Bundles
Spent fuel bundles from boiling water reactors (BWRs), typically 8x8 or 9x9 arrays of irradiated fuel rods in stainless steel channels. Classified in HTS 2844.50.00.00 as irradiated elements with complex fission product mixtures. Common in US plants like those operated by Exelon.
AGR Spent Fuel Cartridges
Spent graphite-moderated fuel cartridges from Advanced Gas-cooled Reactors (AGR), containing uranium oxide pins in steel tubes. Under HTS 2844.50.00.00 as irradiated elements from UK reactors. Designed for Magnox/AGR reprocessing pipelines.
CANDU Spent Fuel Bundles
Spent natural uranium fuel bundles from CANDU heavy-water reactors, 37-element design in stainless steel. Classified HTS 2844.50.00.00 as irradiated cartridges for Canadian export reprocessing. Low burn-up enables on-site storage.
