PFAS Reporting Worksheet
PFAS questions now arrive from customers, regulators and retailers at the same time. This worksheet gives compliance teams a structured inventory of PFAS in purchased parts, with a running annual mass so the scale of exposure is visible.
| Part number | Supplier | PFAS use | PFAS substance | CAS number | Part mass (g) | PFAS concentration (ppm by weight) | Units per year | PFAS per year (g) | |
|---|---|---|---|---|---|---|---|---|---|
75,600 | |||||||||
108,000 | |||||||||
30,000 | |||||||||
94,050 |
Concentration is the PFAS share of the part by weight in parts per million. Request supplier data for each entry and mark unknowns clearly. Reporting definitions and thresholds differ by jurisdiction, so check the current rule before using this for a filing.
Match supplier chemical data to ERP parts
Optional: talk through a private assistant that links supplier declarations to part numbers and volumes.
Optional. The tool and every export work without this. No spam.
How to use the worksheet
Add a row for each part you know or suspect contains PFAS. Record the substance, CAS number and the concentration your supplier reports in parts per million by weight. Enter the part mass in grams and annual volume. The sheet multiplies these to give grams of PFAS per year per part and in total. Use the example rows as a pattern, then replace them with your own data and export to Excel for supplier follow-up.
- Start with cables, seals, coatings, lubricants and membranes
- Record unknown concentrations as a gap to chase
- Keep the supplier statement date for each row
The method behind it
PFAS are a large family of fluorinated substances, and fluoropolymers such as PTFE, FEP and PVDF are common in electronics and industrial parts. In the United States, TSCA section 8(a)(7) requires reporting of PFAS manufactured or imported since 2011, including as part of articles, subject to the rule's terms and dates. In the EU, restriction proposals under REACH are under discussion. Mass per year is simple arithmetic: part mass times concentration times volume.
Reading the result and common mistakes
The total tells you which parts drive volume, so you can prioritise supplier outreach and substitution. It does not decide whether a duty to report applies. Definitions, exemptions and de minimis rules vary, so use the result as an input to your regulatory review.
- Counting only the polymer and missing processing aids and coatings
- Using percent where parts per million is expected
- Not tracking imported articles in finished goods
- Relying on a verbal supplier answer
Frequently Asked Questions
What does PFAS stand for?
Per- and polyfluoroalkyl substances. They are fluorinated chemicals valued for heat, chemical and water resistance, and many persist in the environment. The exact definition used differs between regulators, so check the rule that applies to you.
Is PTFE a PFAS?
Under broad definitions such as the OECD 2021 definition, fluoropolymers like PTFE are included. Some regulators treat them differently. Confirm how the specific rule you are subject to defines the scope.
How do I get concentrations from suppliers?
Send a supplier survey that asks for the substance, CAS number, concentration range and use for each part. Request a signed declaration and, where needed, analytical test results. Record the date and keep the response with the part record.
Does the worksheet file a report for me?
No. It organises the data and computes annual mass. A regulatory filing needs to follow the specific rule, such as the TSCA reporting form and submission tool, with your legal and compliance review.
If you want PFAS supplier answers matched to ERP part numbers and volumes automatically, we can help build that on your own infrastructure.
