To the best of my knowledge this code of practice is only binding to the signaturies, I guess you could say it's alot like the Keyoto (Spelling?)agreement on global warming ;if you havn't signed up (Australia, America,....) it's not your problem ! So if you look at that 'code of practice' document and use the list of companies that have signed up as a list of firms not to do business with, you have your self someware to start. As far as this Toluene thread is concerned i may as well have my say.There are many NP that are OTC in Oz that don't require this much effort (Xylene) Start with a google search for the MSDS of the solvent you are looking for, once found work your way back down the supply chain until you find it at a retail level.Really "Toluene, what the f**ck !!"
