That is why only ASR is allowed to make large quantities of fuel.
We never had problems in making small amounts of fuel for testing etc.
I think the license(in RSA) goes for any material that generates its' own oxygen.In other words, it can burn in an enclosed area, making a potential risk for using it as a explosive in a bomb etc...
You can google any one of those fuels and find their synthesis online.
