IPIA members work closely with the Revenue Commissioners and other State agencies to seek to eradicate illegal activities such as the passing off of laundered fuel or the evasion of excise duty. IPIA member companies individually implement particular procedures and precautions in their own companies to ensure adherence to this principle. IPIA members agreed a Code of Conduct so as to leave no ambiguity about the IPIA policy of only selling oil products to fully legitimate businesses.
