The agreement also aims to minimize the quantity and toxicity of waste generated, to ensure its environmentally sound management as close as possible to the source of production and to assist least developed countries in the environmentally sound management of the hazardous and other wastes they produce. In addition to the above-mentioned conditions for the import and export of waste, there are strict requirements for the notification, authorisation and monitoring of transboundary shipments of waste. It should be noted that the Convention provides for a general ban on the export or import of waste between Contracting Parties and non-Parties. The exception to this rule is when the waste is subject to another contract that does not comply with the Basel Convention. The United States is a notable non-party to the convention and has a number of such agreements to authorize the shipment of hazardous wastes to the countries of the Basel Party. In addition, it is sufficient to add waste to Annex II, which lists other wastes, such as household waste and residues from the incineration of household waste, to fall within the scope of the Convention.  With the strengthening of environmental legislation (e.g. B RCRA) in industrialized countries in the 1970s, the cost of disposing of hazardous waste increased dramatically. .
