CANDU Heavy Water Nuclear Reactor
CANDU reactors use heavy water as moderator and coolant, enabling use of natural uranium fuel. This complete nuclear reactor system is covered by HTS 8401.10.00.00.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If importing heavy water separately for reactor use
Heavy water (deuterium oxide) is classified as a heavy isotope in Chapter 28.
If for dedicated parts of CANDU-type reactors
Specific parts and accessories have separate provisions in 8401.
If classified by heat exchange function if incomplete
Reactor primary circuits may be seen as turbojet/turbine parts if not full reactor.
