Industrial use means use at a site at which one or more chemical substances or mixtures are manufactured including imported or processed.
Intended for use by children means the chemical substance or mixture is used in or on a product that is specifically intended for use by children age 14 or younger. A chemical substance or mixture is intended for use by children when the submitter answers yes to at least one of the following questions for the product into which the submitters chemical substance or mixture is incorporated:
1 Is the product commonly recognized i.e., by a reasonable person as being intended for children age 14 or younger?
2 Does the manufacturer of the product state through product labeling or other written materials that the product is intended for or will be used by children age 14 or younger?
3 Is the advertising, promotion, or marketing of the product aimed at children age 14 or younger?
Manufacture means to manufacture for commercial purposes.

Manufacture for commercial purposes means: 1 To import, produce, or manufacture with the purpose of obtaining an immediate or eventual commercial advantage for the manufacturer, and includes among other things, such manufacture of any amount of a chemical substance or mixture:
i For commercial distribution, including for test marketing.
ii For use by the manufacturer, including use for product research and development, or as an intermediate.
2 Manufacture for commercial purposes also applies to substances that are produced coincidentally during the manufacture, processing, use, or disposal of another substance or mixture, including both byproducts that are separated from that other substance or mixture and impurities that remain in that substance or mixture. Such byproducts and impurities may, or may not, in themselves have commercial value. They are nonetheless produced for the purpose of obtaining a commercial advantage since they are part of the manufacture of a chemical product for a commercial purpose.
Manufacturer means a person who manufactures a chemical substance.
Perand polyfluoroalkyl substances or PFAS, for the purpose of this part, means any chemical substance or mixture that structurally contains the unit R-CF2-CFRR. Both the CF2
and CF moieties are saturated carbons.
None of the R groups R, R or R can be hydrogen.
Site-limited means a chemical substance is manufactured and processed only within a site and is not

distributed as a chemical substance or as part of a mixture or article outside the site. Imported chemical substances are never site-limited.
Worker means someone at a site of manufacture, import, or processing who performs work activities near sources of a chemical substance or mixture or directly handles the chemical substance or mixture during the performance of work activities.
705.5 Substances for which reports must be submitted.

The requirements of this part apply to all chemical substances and mixtures that are PFAS, consistent with the definition of PFAS at 705.3. This includes, but is not limited to, all PFAS
listed or otherwise described in this section. This section contains 5 listings of examples of chemical substances or mixtures that meet this definition.
Paragraph a of this section is a list of chemical substances on the TSCA
Inventory that have an associated Chemical Abstract Services CAS
Registry Number. Paragraph b of this section is a list of chemical substances that have an associated TSCA Accession Number. Paragraph c of this section is a list of chemical substances that have both an associated low-volume exemption LVE case number and a non-confidential CASRN. Paragraph d of this section is a list of chemical substances with an LVE case number but no CASRN. Paragraph e of this section is a list of structural diagram examples of PFAS and those CASRNs.
