About HS Code 284510

Heavy water, or deuterium oxide (D2O), is a form of water containing a higher concentration of deuterium, a heavier hydrogen isotope. Its primary use is as a neutron moderator and coolant in certain types of nuclear reactors, particularly CANDU reactors, due to its low neutron absorption cross-section. Beyond nuclear energy, heavy water is vital in scientific research, including nuclear magnetic resonance (NMR) spectroscopy, and in the production of deuterium-labeled compounds for pharmaceutical and biochemical studies. Trade involves specialized chemical manufacturers, nuclear power utilities, and research institutions worldwide. Key aspects include its strategic importance for nuclear energy programs and the associated non-proliferation controls, as well as its high purity requirements for scientific applications. The market is driven by both energy and advanced research demands.

Products Under This Code
