About the Inventory Expert Service (IES)
IES is available to help you complete your EPA TSCA PMN application under the Revisions of Premanufacture Notification Regulations: Final Rule by obtaining CA Index Names and CAS Registry Numbers® from the CAS chemists who compile, search, and maintain the TSCA Inventory.
By relying on CAS, you will be taking advantage of the in-depth knowledge CAS staff have acquired concerning TSCA submission policies. For example, should you request a CAS Registry Number for a hydrated substance to be reported to the EPA, CAS will provide you with the CAS Registry Number for the anhydrous substance along with the guidance that hydrates are excluded from TSCA reporting.

Processing Your Request
- Complete Part I, Section B (pages 4-6) and Part II, Section A (page 8, if applicable) of the EPA PMN form, and submit these pages and the Inventory Expert Service Order Form to the CAS Inventory Expert Service for processing.
Within 10 working days, CAS will return to you a CA Index Name and a CAS Registry Number (if appropriate) for each substance included in the request.
- CAS Inventory Expert Service offers a Super Rush service. CAS will return to you a CA Index Name and a CAS Registry Number within 3 working days for the Super Rush service once all of the information for processing is received. If during our chemists’ review we discover errors, inconsistencies, or missing data that requires CAS chemist consultation beyond the standard, an additional fee will be applied.
- Please consult What To Include for IES to find what is required for the complete chemical identity for Class 1 and Class 2 substances. It is best to submit the same chemical identity information to IES that will be submitted to EPA. The cost per substance of Class 1 and Class 2 substances submitted is based on CAS chemists' extensive knowledge of the EPA TSCA substance identification requirements.
- Processing is strictly confidential. CAS employs extensive security policies and procedures relating to both physical security and the handling of customer-supplied information. These procedures include detailed measures outlining the labeling, handling, tracking, and storage of documents, computer access, and verbal communication regarding a given request. Without written permission, CAS will only discuss the details in a request with the individual who submitted it.
Note: If you request assignment of a CAS Registry Number for substances not already present in the CAS REGISTRYSM, that assignment makes your substance publicly available in the CAS REGISTRY database. Customer identity information will be kept confidential. If you wish to maintain confidentiality for your substance's identity, you should request only a CA Index Name.
