Current List of Chemical Substances Subject to TSCA ... - Seton

should be aware that they have an affirmative obligation to review the Federal Register for
future publication of actions that may trigger section 12(b) reporting obligations. This list
should not be relied upon in lieu of relevant Federal Register documents, orders, or the Code of
Federal Regulations, and in the event of a conflict between this list and any Federal Register
document, order, or the Code of Federal Regulations, this list will not be considered controlling.
Exporters are encouraged to check this list from time to time, as EPA intends to revise it
periodically, and will do so without prior public notice. EPA also encourages exporters or others
to alert the Agency to any errors or omissions in the list. Comments can be sent to
ccd.citb@epa.gov.
Notes:
1. Chemical substances subject to TSCA section 4 actions “sunset” after a specific period of
time (see “Sunset Date/Status of TSCA Section 4 Testing, Reimbursement, and Reporting
Requirements and TSCA Section 4-Triggered TSCA Section 12(b) Export Notification
Requirements” at < http://www.epa.gov/opptintr/chemtest/sunset.htm > for the latest
sunset table and further information). Be aware that a section 4 chemical that has “sunset”
may also be the subject of another TSCA action triggering export notice requirements so that
export notice may still be required.
2. In some instances, the CAS Registry Number originally cited has been revised or replaced by
CAS since the issuance of the triggering TSCA action. Consequently, other information
sources and indices may reference this “new” CAS number for the same chemical substance
and may or may not cross-reference the originally cited CAS Registry Number contained in
the TSCA regulatory action. Where EPA is aware of such changes, a cross-reference
from the new CAS number to the originally published CAS number is provided.
