Brazil deposited its instrument of ratification for the Comprehensive Test Ban Treaty (CTBT) on July 24 and the Brazilian legislature ratified the nuclear Non-Proliferation Treaty (NPT) on July 13. Brazil is expected to formally deposit its instrument of accession for the NPT in the next few weeks.

Eight other such states (Australia, Austria, Britain, France, Japan, Peru, Slovakia and Spain) have already deposited their instruments of ratification.
