Unlisted substances

Substances classed as no longer polymers . These are listed polymers which were considered to be polymers under the NONS 82 definition but not by the NONS 93 version. Unlisted substances may also be exempt if they could have been considered under NONS 82, or are not a polymer under NONS 93, or were placed on the market between 1 January 1971 and 1 November 1993. 

By applying the procedures mentioned above, monomers and additives can be adequately tested. However, other components, the NlASs, can be present in the food contact material and potentially migrate to food. Such unlisted components are gaining renewed attention. In principle, they are already regulated in Article 3 of Framework Directive EC 1935/2004, i.e., food contact materials should not endanger human health. Unlisted substances that could be found in food contact materials may include ... 

Renewed attention to unlisted substances is stimulated by efforts to enhance consumer protection. Recent examples of unlisted substances originating from packaging materials are ... 

At the heart of the TSCA is a premanufacture notification (PMN) requirement under which a manufacturer must notify the EPA at least 90 days prior to the production of a new chemical. In this context, a new chemical is a chemical that is not listed in the TSCA-based Inventory of Chemical Substances or is an unlisted reaction product of two or more chemicals. Eor chemicals already on this list, a notification is required if there is a new use that could significantly increase human or enviromnental exposure. No notification is required for... 

Many of the above substances are NOT U.S. EPA priority pollutants. No EPA methods are available for these unlisted compounds. 

As regards monomers, the list is complete and contains 206 substances or groups of substances. Accordingly, it rules out the use of an unlisted monomer at the Community level (positive list). Member States may, however, authorise the use of monomers which appear in Section B of Directive 90/128/EEC until 31 December 2001 (78 sub-... 

RCRA has identified listed and unlisted waste streams that are regulated as hazardous wastes and thus regulated as CERCLA hazardous substances. The RQ for each RCRA hazardous waste stream is listed in 40 CFR 302.4. RCRA wastes may be treated as mixtraes only if all hazardous components and their concentrations in the mixture are known. Otherwise, the RQ for the waste stream must be used. The CWA mixture rule also applies to unlisted characteristic wastes if the concentrations of all the constituents in the waste are known. 

Note Unlisted hazardous substances have the reportable quantity of 100 pounds, except for those unlisted hazardous wastes which exhibit extraction procedure (EP) toxicity, as explained in 302.5(b). ...
