For problematic substances, there is no obligation to provide a waybill. Problematic substances are hazardous wastes generated in private households or comparable establishments – as long as they are held by the original waste producer. Also hazardous waste from companies may be regarded as problematic substances if they are, in terms of type and quantity, comparable to hazardous waste generated in private households. Hazardous wastes can constitute problematic substances only as long as they are held by the original waste producer. Also the transfer of hazardous waste by private households is not subject to the obligation to provide a waybill.
