However, the Agency should allow enterprises, upon their request and where necessary, to describe the chemical identity of certain substances in a way that does not put the confidential nature of their businesses at risk. Where the Agency refuses such a request, an appeal should be allowed in accordance with this Regulation. The appeal should have a suspensive effect, so that the confidential information with regard to which the request has been made, should not appear on the label while the appeal is pending.
