                  Subpart B--Specific Chemical Listings
 
Sec. 716.120  Substances and listed mixtures to which this subpart applies.

    Substances listed in this section appear in order by Chemical 
Abstract Service Registry Number. Chemical mixtures and categories are 
listed separately and by alphabetical order. Chemical substances listed 
within a category are provided only as examples of the category, and are 
not included on the list of substances. When a chemical substance in the 
substance or category list had been listed previously by a trivial (or 
common) name, it appears first, followed by the Chemical Abstract 
Service (CAS) name appearing in the TSCA Chemical Substance Inventory.
    (a) List of substances. The following chemical substances are 
subject to all the provisions of part 716. Manufacturers, importers, and 
processors of a listed substance are subject to the reporting 
requirements of subpart A for that substance.
