The overseas produced drugs are legally required for lethal (dødelige) injections, BBC online reports Wednesday.
More than 500 people are on death row in Vietnam for crimes including drug trafficking (narkohandel), rape and corruption.
The South East Asian country stopped using firing squads for executions in 2011, citing the rising cost, a lack of suitable grounds and the stress caused to executioners.
