This page provides resources for using the PFAS Product Reporting Information System for Manufacturers (PRISM), which is used by manufacturers and their representatives to submit PFAS in product reports and pay related fees. PRISM is used by everyone to view PFAS in product data, except trade secrets, after a review period.
PRISM was created and is maintained by the Interstate Chemicals Clearinghouse under contract from the Minnesota Pollution Control Agency. PRISM is based on the High Priority Chemicals Data System, which is already familiar to many manufacturers. Reporting PFAS in products through PRISM will satisfy Minnesota’s requirements and may also meet reporting requirements of other states.
Reported data that is not a trade secret will be available to the public after the MPCA reviews and publishes the information in PRISM. Report publishing will be an ongoing process as reports are submitted.
PFAS reporting system
PFAS Product Reporting Information System for Manufacturers (PRISM) is used by manufacturers and their representatives to submit PFAS in product reports and pay related fees. PRISM is used by everyone to view PFAS in product data, except trade secrets, after a review period.
PRISM resources
PRISM reporting guide
The PRISM user guide covers the basics of getting started in PRISM, data entry, and fee payment.
Supplemental reporting guide to PRISM
The supplemental guide offers assistance with different reporting scenarios, including how to report similar products, customized products, replacement parts, and more. This guide also addresses situations like reporting in groups, reporting on behalf of another company, requesting trade secret status of a chemical name, and managing incomplete data from suppliers.
Technical support
If you experience technical issues within the PRISM system, please email prism@theIC2.org for assistance. For questions on how to report or reporting requirements, please email pfasreporting.mpca@state.mn.us.
If your technical support request received by email would be more easily addressed through live virtual support with screen sharing, you will be invited to virtual office hours with MPCA staff.
Requesting trade secret status
Minnesota rules and statutes protect trade secrets in PFAS in products reporting as not public data.
Manufacturers may request a PFAS chemical name or identifier receive trade secret status as part of the data entry process in PRISM. See page six of the supplemental reporting guide for more information.
If you have additional questions on non-chemical name and identifier number trade secret requests, please email prismtradesecret.mpca@state.mn.us.
Trade secret requests and related data are not public while the request is under consideration.
How-to videos

PRISM tips
- Required information for creating a PRISM account
To register for a PRISM account, you will need to provide the account holder’s name, job title, telephone number, and email address.
To register your company’s profile, you will need to provide the company name, NAICS or SIC code, company mailing address, and company physical address if different from mailing address.
- Only one PRISM account required per manufacturer
PRISM accounts are per manufacturer, not location. A company with multiple locations needs to only register once. If a company has multiple business units, doing business as (DBAs), or subsidiaries, the parent company can decide whether to report under the parent company or separately.
- Register multiple users to maintain access through staffing changes
Employee turnover is common. The Minnesota Pollution Control Agency (MPCA) recommends companies register at least two active users in the PFAS Reporting Information System for Manufacturers (PRISM) so that your company’s access to PRISM continues if a PRISM user leaves your organization.
Once a company is registered in PRISM, additional authorized users may be added. The first user is automatically designated as the company’s public contact and billing contact in PRISM. A user with the public contact designation may reassign these roles to anyone under their company.
User accounts for a company can be deactivated at any time, except for a user assigned the public contact role. The public contact role must be removed from a user before they can be deactivated. To deactivate a user who is the company’s public contact in PRISM, you must first reassign the public contact role to another user.
Contact the PRISM administrator if your company’s public contact leaves your company before the role is reassigned.
For more information on managing your company’s users in PRISM, please see pages 18 – 21 of the PRISM reporting guide.
- No intentionally added PFAS, no reporting required
If your products don’t contain intentionally added PFAS, your company does not need to report or create an account in PRISM.
"Intentionally added PFAS” means PFAS were deliberately added during the manufacture of a product where the continued presence of PFAS is desired in the final product or one of the product's components to perform a specific function.
The MPCA encourages manufacturers to maintain records documenting the basis of your PFAS in product determination, including any supplier certifications or communications confirming that your products do not contain intentionally added PFAS.
Please reevaluate your PFAS in product reporting obligations if your products or supplier information changes.
- Manufacturer date exemption applies to products, not product components
Products made before July 1, 2023 are exempt from reporting requirements. Products made after July 1, 2023 must be reported. This exemption date applies to the manufacture date of the final product and not individual components within the product.
For example: A valve was manufactured in 2024. The only component of the valve containing intentionally added PFAS is an o-ring that was manufactured in 2022. Because the valve is the final product, the valve and its o-ring must be reported to meet Minnesota’s PFAS in product reporting requirements.
- Reporting requirements may be met before reports are published
Reporting requirements are met when complete reports are submitted with fee payment. Reports will appear in the public system after the MPCA completes its review and confirms the information is ready for release. You do not need a PRISM account to view the public data.
- Understanding fees and payment options
Reporting fee: A one-time reporting fee of $800 per manufacturer is due when an initial report is submitted through the PFAS Reporting Information System for Manufacturers (PRISM). Payments made through PRISM are subject to a payment processing fee.
PRISM accepts payment by:
- automated clearing house (ACH, checking or savings account)
- credit card
- debit card
Initial reports with payment are due Sept. 15, 2026.
Manufacturers requesting a reporting waiver must include a $800 check with their waiver request form. Electronic payments are not accepted for waiver requests.
Waiver request forms with payment must be postmarked at least 30 days before the reporting due date. Forms are available on the PFAS reporting webpage.
Organizations requiring onboarding documentation for internal accounting or procurement purposes may request an MPCA W-9 form, including the agency's Tax Identification Number (TIN).
Please email pfasreporting.mpca@state.mn.us to be put in contact with the MPCA financial teams for these requests.
- Requesting a PFAS addition in PRISM
Reporting a product in the PFAS Reporting Information System for Manufacturers (PRISM) includes identifying which PFAS chemicals are intentionally added to the product. You can select PFAS in columns of G and I of the data entry screen and view all PFAS chemicals found in PRISM in a reference sheet on the downloadable Excel template.
Over 10,700 PFAS chemicals are found in PRISM. If a PFAS chemical you need to report is missing, the Minnesota Pollution Control Agency (MPCA) will add it to the system at your request. To request a PFAS chemical addition, write to pfasreporting.mpca@state.mn.us with the follow information:
- Chemicals Abstracts Service Registry Number (CASRN), if available
- Toxic Substance Control Act Registration Number (TSCARN) or TSCA Accession Number, if applicable
- European Community (EC) Number, if applicable
- International Union of Pure and Applied Chemistry (IUPAC) chemical name, if available
Providing these identifiers helps us verify the chemical and expedite its addition to the PRISM system, minimizing delays in completing your report.
- Avoid validation errors by selecting the correct PFAS name
PRISM uses the International Union of Pure and Applied Chemistry (IUPAC) naming convention for PFAS chemical names whenever possible. Ensuring you enter the correct PFAS name in the system will help avoid validation errors when creating a report.
When using the web-based PRISM user interface for data entry, you can click the search glass icon in the PFAS Name column. A pop-up box will appear where a user can search by:
- name
- Chemical Abstracts Service Registration Number (CASRN)
- Toxic Substances Control Act Registration Number (TSCARN)
- European Community (EC) numbers.
We recommend using any of the identification numbers when searching to ensure the corresponding chemical is used and not missed, rather than searching by a chemical brand name or a common chemical name abbreviation.
If you are working in Excel on the downloadable reporting template to compile data, please use the PFAS Reference sheet to search for the chemical using any of the known chemical identifying number for best search results. The template does not have the same pop-up search box as the browser-based interface. Copy and paste the PFAS chemical name to ensure the IUPAC naming convention is used in the template to avoid validation errors.
There are over 10,700 PFAS chemicals in PRISM. If an appropriate PFAS chemical name cannot be found, please email the PRISM administrators.
- Understanding the PFAS Identifier Type column
When completing a report in the PFAS Reporting and Information System for Manufacturers (PRISM), complete the “PFAS Identifier Type” in column G before entering data in columns H and I.
Column G in the PRISM system has five dropdown options that provide validation logic to the various options you can report for PFAS Name in column I.
The “CASRN,” “TSCARN,” and “EC” options for column G help validate text selected or typed into PFAS Name (column I) against chemical entries in the PRISM system.
Selecting the “TOF” option for column G allows a user to select “TOF” in the PFAS Name column if they are using total organic fluorine (TOF) test results in place of unknown PFAS chemicals.
“Other” is the last option for column G, which allows users to type in a custom text response in the PFAS name column in instances where Chemical Abstracts Service Registration Number (CASRN), Toxic Substances Control Act Registration Number (TSCARN), or European Community (EC) numbers are not available. Using “Other” in column G requires users to enter the other numerical code they are using in column H, “Other PFAS Identifier Type Name.”
Please contact the MPCA at pfasreporting.mpca@state.mn.us before using the “Other” option in column G or if a PFAS chemical you need to report with a CASRN, TSCARN, or EC identifier number needs to be added to PRISM.
- Reporting similar products
PRISM offers users three time-saving ways to report on PFAS in similar products or similar product components when reporting.
- Product grouping: When a manufacturer produces similar products that only differ in superficial qualities such as color or size but have a similar form and function, the products can be grouped if the same PFAS chemicals are used in the product and the PFAS chemicals are providing the same function.
Example: Paints R Us has a line of interior household paint. The premium version of this paint is available in three different gloss finishes. The same PFAS chemical is used in this premium line of paints and is present in the same chemical concentration ranges. The PFAS chemical in this line of paint serves the same function(s). These paints could be grouped under one product reported.
- Component grouping: When a product contains multiple components that contain PFAS, similar PFAS containing components can be grouped if they only differ in superficial qualities.
Example: A lawnmower manufacturer has a lawnmower that contains multiple components with PFAS. One of these components are gaskets. There are many gaskets throughout the mower made of PTFE. The component “gaskets” only need to be reported once as a component if they only differ superficial qualities, the PFAS in the gaskets provide the same function(s), and concentration of PTFE in each is within the same range (i.e., 90-100%).
- Combining each grouping option: When reporting a product that contains many PFAS containing components, manufacturers should group products into product models or product families whenever applicable. Once those overarching products have been grouped, a manufacturer should then group all similar PFAS containing components where applicable.
See pages 2-3 of the supplemental reporting guide for more examples and illustrations on reporting similar products. Have questions on allowable product or component grouping? Please email pfasreporting.mpca@state.mn.us.
- Product grouping: When a manufacturer produces similar products that only differ in superficial qualities such as color or size but have a similar form and function, the products can be grouped if the same PFAS chemicals are used in the product and the PFAS chemicals are providing the same function.
- Enable macros to use the Excel spreadsheet
Avoid validation problems by enabling macros in Microsoft Excel.
A report in the PFAS Reporting Information System for Manufacturers (PRISM) may be entered in two ways. Users may either enter data directly into PRISM using a web browser (PRISM is designed for Chrome) or download a Microsoft Excel reporting template from PRISM to upload after completing.
For the template to work correctly, PRISM users must enable macros in Microsoft Excel.
Excel macros can automate predefined operations and help streamline repetitive tasks. In PRISM, macros are built into the downloadable template to provide real-time validation and updates, such as newly added PFAS chemicals, after the template has been downloaded.
For security purposes, most operating systems require users to unblock the template file and enable macros before use. PRISM users should only follow these steps for files obtained from PRISM. Macros are supported in the desktop version of Excel and may not function in an in-browser environment.
For more on how to enable macros, see pages 28 and 29 of the PRISM user guide. If the file properties do not display an option to unblock the file as shown in the user guide, please contact your company’s IT department, as they may have additional security steps enable macros.
