The AFFF lawsuit tiers system is what determines how much money you can receive from a firefighting foam cancer settlement. The higher your tier, the more severe your diagnosis, and generally, the larger your potential payout.
Tens of thousands of military personnel, civilian firefighters, and airport workers have filed claims through MDL 2873 in South Carolina federal court. This case is one of the largest mass torts in U.S. history, with settlements from 3M, DuPont, Tyco, and others totaling over $13 billion.
If you or someone you love was exposed to AFFF foam and later diagnosed with cancer, understanding how these tiers work is the single most important thing you can do right now.
This article breaks down every tier, every qualifying cancer, every payout range, and every deadline that matters in 2026.
AFFF Lawsuit Tiers: The Big Picture
The AFFF lawsuit tiers are a ranking system that places cancer diagnoses into categories based on the strength of the scientific link between PFAS chemical exposure and that specific cancer.
Think of it like a hospital triage system. The most well-documented, most serious cancers go to the front of the line. Claimants in higher tiers receive priority consideration and larger baseline compensation values.
These tiers were developed as part of the global settlement framework negotiated within MDL 2873. Settlement administrators and plaintiffs’ steering committee attorneys worked together to create a matrix that reflects the current scientific evidence.
Not every defendant uses the exact same tier language. But the core logic is consistent across the major settlements.
| Tier Level | General Description | Example Cancers |
|---|---|---|
| Tier 1 | Strongest scientific link | Bladder cancer, kidney cancer |
| Tier 2 | Significant but secondary link | Testicular cancer, thyroid cancer |
| Tier 3 | Emerging scientific evidence | Non-Hodgkin lymphoma, leukemia |
| Tier 4 | Developing evidence | Prostate cancer, certain rare cancers |
What Is an AFFF Lawsuit Tier?
An AFFF lawsuit tier is a classification level assigned to a claimant’s cancer diagnosis that determines their baseline settlement value within the AFFF mass tort.
Each tier reflects how much peer-reviewed science supports a direct causal connection between PFAS exposure from aqueous film-forming foam and that particular cancer type.
The tier assignment does not mean one cancer is “worse” than another in a medical sense. It means the legal and scientific evidence supporting the connection between AFFF exposure and that cancer is stronger or weaker.
Claimants are placed into tiers by their attorneys, often with the help of medical experts and exposure documentation. The settlement administrator then reviews and confirms the placement.
Your tier placement directly affects:
- Your base compensation amount
- Whether you receive an accelerated payment
- How your case is prioritized in the claims queue
- What additional factors (like age, severity, or military service) are applied on top
AFFF Settlement Tiers Explained: How the System Actually Works
The AFFF settlement tier system works by assigning point values or compensation bands to each tier, which are then adjusted by individual factors specific to each claimant.
Here is the honest truth most legal websites skip over: your tier is a starting point, not a final number. Attorneys call this a “settlement matrix” approach.
Each defendant negotiated slightly different matrices. But the underlying framework follows a consistent pattern.
The process works in three stages:
Stage 1: Diagnosis Confirmation
Your medical records establish what type of cancer you have and when it was diagnosed.
Stage 2: Tier Placement
Your cancer is matched to a tier based on the scientific evidence table in the settlement agreement.
Stage 3: Multiplier Application
Individual factors adjust your base amount. These include age at diagnosis, cancer severity, length of exposure, and whether you are a current cancer patient or a survivor.
The final number combines your tier base value with all applied multipliers. Two people in the same tier can receive very different amounts.
Key Takeaway: Tier placement is just the starting point. Individual factors like age, exposure duration, and cancer severity can significantly change your final payout.
AFFF Lawsuit Payout Amounts by Tier: What the Numbers Look Like
AFFF lawsuit payout amounts by tier range from tens of thousands of dollars for lower-tier cancers to several hundred thousand dollars or more for the most serious Tier 1 claims.
Exact figures are not always publicly disclosed because they depend on the specific defendant’s settlement, the claims volume, and how the fund is distributed. That said, publicly available information and legal reporting give us reasonable ranges.
| Tier | Estimated Payout Range | Notes |
|---|---|---|
| Tier 1 | $150,000 to $600,000+ | Strongest link; most common qualifying claims |
| Tier 2 | $75,000 to $250,000 | Growing claim volume in 2025-2026 |
| Tier 3 | $40,000 to $150,000 | Subject to additional documentation requirements |
| Tier 4 | $15,000 to $75,000 | Requires stronger individual exposure proof |
These are ranges based on publicly reported mass tort data. Individual results vary significantly.
The 3M settlement fund of approximately $10.3 billion was structured to cover municipal water system claims. Separate funds cover personal injury plaintiffs.
Attorney fees typically run 33% to 40% of the final settlement amount, which reduces the claimant’s net payout.
AFFF Firefighting Foam Lawsuit Update 2026
As of 2026, the AFFF firefighting foam lawsuit is in active settlement distribution and ongoing litigation, with new personal injury claims still being filed and processed through MDL 2873.
The major defendant settlements that defined the 2023 to 2025 period are now in claims processing mode. That means the tier system is being actively applied to tens of thousands of individual claimants.
Here is where things stand heading into 2026:
- 3M’s $10.3 billion settlement reached in June 2023 targets primarily water contamination claims but also affects how personal injury funds are structured.
- DuPont, Chemours, and Corteva settled for $1.185 billion in June 2023.
- Tyco Fire Products and related defendants settled for $750 million in late 2023.
- Kidde-Fenwal filed for bankruptcy in 2023, complicating claims against that defendant.
- Personal injury bellwether trials continue in federal court for defendants who have not yet settled.
2026 is a pivotal year. The claims administrator is processing the largest wave of personal injury claims in the history of this MDL. If you filed before late 2025, your claim is likely in active review right now.
AFFF Cancer Lawsuit Eligibility: Do You Qualify?
You qualify for the AFFF cancer lawsuit if you had documented exposure to aqueous film-forming foam and were later diagnosed with a cancer linked to PFAS chemicals.
Eligibility is not automatic. You must meet specific requirements related to both exposure and diagnosis.
Exposure Requirements:
- Worked at a military base where AFFF was used during training or firefighting
- Served as a firefighter at a civilian airport that used AFFF foam
- Lived near a military base or airport with documented PFAS contamination
- Worked in industrial settings where AFFF was regularly used
Diagnosis Requirements:
- Diagnosed with a cancer recognized in the settlement tier system
- Diagnosis must be confirmed by medical records
- In most cases, your cancer diagnosis must have occurred after a period of documented AFFF exposure
Key Takeaway: Exposure alone is not enough, and neither is a cancer diagnosis alone. You need both, and you need documentation to prove the connection.
AFFF Lawsuit Qualifying Cancers: Full List by Tier
The qualifying cancers for the AFFF lawsuit are those for which peer-reviewed science has established a meaningful association between PFAS chemical exposure and the disease.
This is not a short list. Researchers have linked PFAS chemicals to a wide range of malignancies, and the tier system reflects where the science is strongest.
| Tier | Qualifying Cancers |
|---|---|
| Tier 1 | Bladder cancer, kidney cancer (renal cell carcinoma) |
| Tier 2 | Testicular cancer, thyroid cancer, breast cancer (certain subtypes) |
| Tier 3 | Non-Hodgkin lymphoma, leukemia (certain types), pancreatic cancer |
| Tier 4 | Prostate cancer, ovarian cancer, colorectal cancer, liver cancer |
Some cancers that do not appear on this list may still qualify depending on the individual defendant settlement agreement and the strength of individual exposure documentation.
Mesothelioma from asbestos is a separate lawsuit entirely. Do not confuse the two.
AFFF Lawsuit Who Qualifies: Beyond the Basic Checklist
People who qualify for the AFFF lawsuit include not just the individuals directly exposed, but in certain cases, their surviving family members if the exposed person has passed away.
This is where many claimants do not realize they have a case. Wrongful death claims are a real part of this litigation.
Who can file:
- Active-duty military members who trained with AFFF foam at U.S. military installations
- Veterans who served at bases known to use AFFF in fire training
- Airport firefighters and ground crew who used AFFF as part of their jobs
- Industrial workers at facilities that used AFFF foam regularly
- Family members filing on behalf of a deceased AFFF-exposed person
Who likely does not qualify:
- People diagnosed before any documented AFFF exposure
- People whose cancer has no recognized link to PFAS in any settlement tier
- Claimants who cannot provide any exposure documentation
It is worth knowing that exposure documentation does not have to be perfect. Employment records, base assignment records, or witness testimony from co-workers can all support a claim.
How AFFF Settlement Tiers Are Determined: The Inside Process
AFFF settlement tiers are determined by matching your specific cancer diagnosis to a scientific evidence matrix built into each defendant’s settlement agreement.
Your attorney plays the central role in this process. They review your medical records, your exposure history, and the current tier criteria for each defendant settlement you qualify under.
The process is not arbitrary. It follows a structured framework that the plaintiffs’ steering committee and defendants’ counsel negotiated over years of litigation.
Here are the key factors that go into tier determination:
- Primary diagnosis: The type of cancer, confirmed by pathology
- Scientific literature: Studies linking that cancer to PFAS exposure
- Exposure intensity and duration: How long and how heavily you were exposed
- Latency period: Whether the time between exposure and diagnosis fits expected PFAS patterns
- Defendant-specific criteria: Each settlement may classify the same cancer differently
Think of this process like applying for disability benefits. You fill out your application, submit your documentation, and a reviewer checks your case against the established criteria. The difference is that your attorney handles most of the heavy lifting.
Key Takeaway: Tier determination is not something you do alone. It is a structured, documented process driven by your medical records, your exposure history, and the specific settlement agreement that applies to your case.
AFFF Tier 1 Compensation: The Highest Payout Category
Tier 1 AFFF compensation applies to claimants diagnosed with cancers that have the strongest scientific link to PFAS exposure, specifically bladder cancer and kidney cancer.
These two cancers have been the most extensively studied in connection with PFAS chemicals. Multiple peer-reviewed studies, including large-scale epidemiological research, have found statistically significant associations between PFAS blood levels and both bladder and renal cell carcinoma.
Because the science is strongest here, Tier 1 claimants receive the highest baseline compensation values.
Bladder Cancer Claimants:
Bladder cancer was one of the earliest cancers flagged in PFAS research. Firefighters and military personnel with high PFAS exposure showed elevated rates of bladder cancer in occupational health studies.
Kidney Cancer Claimants:
Renal cell carcinoma is the most common type of kidney cancer linked to PFAS. Studies following communities near PFAS-contaminated water supplies found kidney cancer rates significantly above expected levels.
| Factor | Effect on Tier 1 Payout |
|---|---|
| Age at diagnosis (under 50) | Higher multiplier applied |
| Active cancer at time of claim | Higher compensation |
| Multiple diagnoses | Can affect total value |
| Years of exposure (15 or more) | Increases base value |
| Severity/stage at diagnosis | Stage 3-4 typically receives more |
Tier 1 claims are also typically processed with higher priority by the claims administrator.
AFFF Tier 2 Compensation: What to Expect in This Category
Tier 2 AFFF compensation covers claimants with cancers that have a strong but secondary level of scientific support, including testicular cancer and thyroid cancer.
These cancers are well-documented in PFAS research but received slightly less weight in settlement negotiations because the peer-reviewed evidence base, while solid, is not as extensive as for bladder and kidney cancers.
Testicular cancer in younger male claimants, particularly veterans and military firefighters, has been a significant part of Tier 2 claims. Thyroid cancer, especially in female claimants, has also grown as a recognized Tier 2 diagnosis.
Important distinction: Tier 2 does not mean your cancer is less serious. It means the litigation-specific evidence framework placed it in a secondary tier. Claimants with advanced-stage Tier 2 cancers can receive payouts that exceed early-stage Tier 1 amounts once multipliers are applied.
| Cancer Type | Tier | Estimated Base Range |
|---|---|---|
| Testicular cancer | Tier 2 | $80,000 to $200,000 |
| Thyroid cancer | Tier 2 | $75,000 to $180,000 |
| Breast cancer (qualifying subtypes) | Tier 2 | $85,000 to $220,000 |
Tier 2 claims are actively being processed in 2026. The volume of Tier 2 claims surged through late 2025 as more thyroid and testicular cancer diagnoses were linked to military PFAS exposure data.
AFFF Tier 3 Compensation: Emerging Science, Real Dollars
Tier 3 AFFF compensation applies to cancers where the scientific connection to PFAS exposure is genuine but still developing, including non-Hodgkin lymphoma, certain leukemia subtypes, and pancreatic cancer.
“Developing” does not mean weak. It means the peer-reviewed body of evidence has not yet reached the same depth as Tier 1 or Tier 2 cancers. For claimants with these diagnoses, that still translates to real compensation.
Non-Hodgkin lymphoma has emerged as one of the most frequently claimed Tier 3 cancers. Studies of firefighters with long careers show elevated NHL rates compared to the general population, and PFAS exposure is considered a contributing factor.
Pancreatic cancer claims in this tier are particularly sensitive because of the diagnosis’s severity. Stage and prognosis weigh heavily in how pancreatic cancer claims are valued.
For Tier 3 claimants, documentation requirements are often stricter. Attorneys typically need:
- Longer exposure history documentation
- Stronger evidence of proximity to AFFF use
- Medical expert opinions connecting the specific cancer to PFAS exposure
- Blood PFAS level testing if available
Key Takeaway: Tier 3 claims require more documentation but are absolutely worth pursuing, especially for non-Hodgkin lymphoma, leukemia, and pancreatic cancer diagnoses linked to documented AFFF exposure.
How Much Is the AFFF Lawsuit Worth? Total Fund Breakdown
The total AFFF lawsuit settlement funds across all major defendants exceed $13 billion, making this one of the largest mass tort recoveries in American legal history.
Here is how that money breaks down:
| Defendant | Settlement Amount | Primary Coverage |
|---|---|---|
| 3M Company | $10.3 billion | Municipal water contamination |
| DuPont / Chemours / Corteva | $1.185 billion | Combined PI and water claims |
| Tyco Fire Products | $750 million | Personal injury claims |
| Kidde-Fenwal | Bankruptcy proceedings | Limited fund available |
| Other defendants | Ongoing litigation | Settlements pending |
For individual claimants, the math does not divide evenly. Personal injury settlements are separate from municipal water contamination funds.
The personal injury pool, which covers cancer claimants, is valued in the hundreds of millions to low billions depending on which defendants’ funds are involved.
One honest reality: the final amount per claimant depends on total claim volume. If more people file, the per-person share of some fund structures decreases. This is exactly why legal advocates strongly encourage early filing.
3M AFFF Settlement Tiers: What Makes This One Different
The 3M AFFF settlement tiers apply differently from other defendant settlements because 3M’s $10.3 billion fund was structured primarily around water system contamination claims, not personal injury.
This is a critical distinction that most articles gloss over.
When municipalities and water utilities sued 3M for contaminating drinking water supplies, that formed the largest chunk of 3M’s liability. Personal injury claimants (cancer patients) are pursuing 3M through separate channels or through different fund allocations.
For personal injury purposes, 3M’s settlement structure still recognizes the tier system, but the applicable compensation bands may differ from those used in other defendant agreements.
What this means for claimants:
- If you have a 3M-specific claim based on exposure at a 3M-supplied base or facility, your tier placement follows the 3M agreement framework.
- If your exposure occurred through municipal water contamination, you may be in a different claimant category entirely.
- Most personal injury claimants have claims against multiple defendants, not just 3M.
Your attorney should have filed your claim against every applicable defendant in MDL 2873, not just 3M. If that did not happen, it is worth a conversation.
DuPont AFFF Settlement Tiers: Separate Fund, Same Tier Logic
The DuPont AFFF settlement tiers come from the $1.185 billion settlement reached in June 2023 by DuPont, its spinoffs Chemours and Corteva, and cover both water contamination and personal injury claims.
DuPont manufactured PFAS chemicals under the brand names Teflon and others for decades before eventually spinning off its PFAS business into Chemours. Both companies are defendants in MDL 2873.
The DuPont settlement structure uses a similar tier logic to other defendants, but the fund size and the specific claimant allocation method differ.
Key DuPont settlement facts:
- Settlement announced: June 2023
- Total fund: $1.185 billion (shared with Chemours and Corteva)
- Coverage: Approximately 300 water systems plus personal injury claims
- Tier system: Follows MDL 2873 framework
For personal injury claimants, DuPont exposure typically came from:
- Living near or working at DuPont manufacturing facilities
- Exposure to PFAS chemicals in industrial settings where DuPont products were used
- Military installations supplied with DuPont-manufactured AFFF
The DuPont fund is smaller than 3M’s. Personal injury claimants with claims against DuPont should understand that the per-claimant allocation may differ from what is available through the Tyco or 3M tracks.
AFFF MDL Settlement Update 2026: Where Things Stand Right Now
The AFFF MDL settlement update for 2026 shows a litigation in active distribution mode, with claims administrators processing tens of thousands of personal injury claims while bellwether trials continue for unresolved defendants.
MDL No. 2873, formally titled “Aqueous Film-Forming Foam Products Liability Litigation,” is before Judge Richard Gergel in the District of South Carolina.
2026 Status Snapshot:
| Status Item | Current Status |
|---|---|
| 3M Settlement | Claims processing underway |
| DuPont/Chemours/Corteva | Claims processing underway |
| Tyco Fire Products | Claims processing underway |
| Kidde-Fenwal | Bankruptcy proceedings, limited fund |
| Remaining defendants | Active litigation, trials expected |
| New claims filing | Still accepted through 2026 |
The MDL continues to receive new case filings. Courts have not issued a blanket closure to new plaintiffs, which is significant.
If you have not yet filed and you have a qualifying diagnosis, 2026 is not too late. But that window is narrowing. Each settlement fund has a claims period, and those deadlines are real.
Key Takeaway: As of 2026, the AFFF MDL is processing claims from multiple settled defendants simultaneously. New claims are still being accepted, but time is running out for many individual settlement windows.
AFFF Lawsuit Claims Process: Step by Step in 2026
The AFFF lawsuit claims process in 2026 follows a structured sequence that starts with eligibility verification and ends with a settlement distribution from the applicable defendant fund.
It sounds complicated but the actual steps are straightforward once you know them.
Step 1: Consult with an AFFF attorney
You describe your exposure history and your diagnosis. The attorney evaluates which defendants you have claims against.
Step 2: Medical records collection
Your attorney requests your full medical history, pathology reports, and diagnosis records.
Step 3: Exposure documentation
Military service records, employment records, and base assignment records are gathered to establish where and when you were exposed.
Step 4: Tier placement
Your attorney matches your diagnosis to the applicable tier under each defendant’s settlement agreement.
Step 5: Claim submission
Your claim is filed with the appropriate settlement administrator for each applicable defendant.
Step 6: Review and allocation
The claims administrator reviews your file, confirms your tier placement, and calculates your allocation.
Step 7: Payment distribution
Settlement payments are distributed according to the fund’s payment schedule.
Most personal injury attorneys handling AFFF cases work on contingency. You pay nothing upfront. Fees come out of your settlement only if you win.
AFFF Lawsuit Filing Deadline 2026: Do Not Miss These Dates
The AFFF lawsuit filing deadline in 2026 varies by defendant settlement agreement, and missing a deadline can permanently bar you from recovering compensation.
This is not a situation where you can wait and see what happens. Settlement funds have claims periods. When those periods close, they close.
Known and Estimated 2026 Deadlines:
| Defendant Fund | Claims Period Status | Notes |
|---|---|---|
| 3M Personal Injury | Active through 2026 | Specific cutoff TBD |
| DuPont/Chemours/Corteva | Active through 2026 | Monitor for official closure |
| Tyco Fire Products | Active through 2026 | Claims administrator reviewing |
| Kidde-Fenwal bankruptcy | Limited window | File as soon as possible |
| Unresolved defendants | Statute of limitations applies | State law varies |
For defendants still in active litigation, state statutes of limitations apply. Most states give you 2 to 3 years from the date you knew or should have known your cancer was linked to AFFF exposure.
The safest advice anyone can give you: Do not assume you have time. File in 2026 if you have not already. Every settlement has a backstop deadline that, once passed, eliminates your eligibility regardless of how strong your case is.
If you are unsure whether your state’s statute of limitations has already run, an AFFF attorney can evaluate your timeline for free.
Frequently Asked Questions
What are the AFFF lawsuit tiers and how do they affect my payout?
The AFFF lawsuit tiers are settlement categories that rank cancer diagnoses by the strength of their scientific link to PFAS exposure.
Your tier placement determines your baseline compensation value, with Tier 1 (bladder and kidney cancer) paying the most and lower tiers paying progressively less.
Individual factors like cancer severity, age at diagnosis, and exposure duration are then applied on top of the tier base to calculate your final payout.
Which cancers qualify for Tier 1 in the AFFF settlement?
Bladder cancer and kidney cancer (renal cell carcinoma) are the primary Tier 1 cancers in most AFFF settlement agreements.
These two cancers have the most peer-reviewed scientific evidence linking them to PFAS chemical exposure from aqueous film-forming foam.
Tier 1 claims typically receive the highest baseline compensation and are processed with priority by the settlement administrator.
How do I find out which AFFF settlement tier I fall into?
Your tier placement is determined by your attorney based on your confirmed cancer diagnosis and the tier criteria in each applicable defendant settlement agreement.
You cannot self-assign a tier. The process requires review of your medical records and matching your diagnosis to the settlement matrix.
An AFFF attorney can review your case and identify your tier placement during a free initial consultation.
What is the 2026 deadline to file an AFFF lawsuit claim?
Each defendant settlement has its own claims period, and most are still accepting personal injury claims through 2026.
However, specific cutoff dates vary, and missing a claims period deadline permanently bars you from that fund.
For defendants still in active litigation, your state’s statute of limitations applies, typically 2 to 3 years from the date of diagnosis or discovery of the AFFF connection.
How much money can I get from the AFFF firefighting foam lawsuit?
Payout amounts range from roughly $15,000 for lower-tier claims to $600,000 or more for severe Tier 1 cases.
The exact amount depends on your tier placement, cancer severity, age at diagnosis, length of exposure, and which defendants your claim is filed against.
Attorney fees of 33% to 40% are typically deducted from the gross settlement amount before you receive your net payment.
What Comes Next
If you have a cancer diagnosis and a history of AFFF exposure, 2026 is a critical year. The largest settlement funds in this litigation are actively distributing money right now.
Knowing your tier is the foundation. Everything else, including your payout, your timeline, and your eligibility, builds on that one piece of information.
Get your medical records together. Locate your exposure history. Reach out to an AFFF attorney who works on contingency so you pay nothing unless you win.
Time is the one thing you cannot get back in a litigation like this.
