Everything You Need to Know About PFAS in 2026

Article Highlights:

• PFAS are a large class of synthetic chemicals that include several thousand individual substances. They’re defined by the presence of at least one fully fluorinated carbon atom, a chemical structure that gives these substances their unique properties.
• Scientific research has linked certain PFAS to a range of adverse health effects. These include increased risk of kidney and testicular cancers, liver damage, immune system suppression, thyroid disease, and reproductive and developmental harm.
• In recent years, PFAS regulation has accelerated at every level of government. Not all directives are the same, however, and it’s critical to distinguish between water-focused regulation and product-based regulation. 
• At the federal level, the EPA’s PFAS reporting rule under the Toxic Substances Control Act (TSCA) represents a foundational shift. Under TSCA Section 8(a)(7), companies that manufactured or imported PFAS or PFAS-containing articles between 2011 and 2022 must report detailed information to the EPA on each covered PFAS. 

Per- and polyfluoroalkyl substances, commonly referred to as PFAS, have become one of the most closely watched classes of chemicals in the world. Their risks—and the regulations cropping up to mitigate those risks—now directly affect market access, product viability, and compliance concerns across multiple industries. In 2026, PFAS are no longer viewed as a niche environmental issue—they sit at the center of public health concerns, regulatory action, and product compliance decision-making across industries. Governments are tightening controls, consumers are demanding transparency, and manufacturers are being asked to identify the presence of PFAS deeper in their products and supply chains than ever before. Understanding what PFAS are, why they are regulated, and how different rules apply is now essential for companies operating in global markets.

To make sense of today’s regulatory and scientific landscape, it helps to start with a clear understanding of what PFAS actually are, and why they behave so differently from other regulated substances.

What Are PFAS?

PFAS are a large class of synthetic chemicals that include several thousand individual substances. They’re defined by the presence of at least one fully fluorinated carbon atom, a chemical structure that gives these substances their unique properties. This carbon–fluorine bond is one of the strongest in organic chemistry, making PFAS highly resistant to heat, water, oil, and chemical reactions. These properties are what originally made PFAS attractive for industrial and consumer applications. It is now also, however, the reason PFAS persist for so long in the environment.

PFAS are commonly referred to as “forever chemicals” because they do not readily break down under natural environmental conditions. Once these chemicals are released in the atmosphere, they can remain in soil, water, air, and living organisms for decades. Some PFAS can transform into other PFAS over time, further extending their environmental footprint. This persistence is central to both the health concerns and the regulatory attention surrounding PFAS.

Among the most well-known PFAS are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), which were historically used in non-stick coatings and firefighting foams. Although many legacy PFAS have been phased out in certain parts of the world, they’ve often been replaced with shorter-chain, alternative PFAS that are now coming under the same level of scrutiny as their predecessors.

How PFAS Are Used and Where They’re Found

PFAS have been used for decades across a wide range of applications due to their durability and resistant properties. In consumer products, PFAS have historically been found in non-stick cookware, stain-resistant carpets and furniture, water-repellent clothing, cosmetics, and grease-resistant food packaging. Even when PFAS are no longer intentionally added, they may still be present as processing aids or impurities.

In industrial and commercial contexts, PFAS play a role in:

• Electronics manufacturing
• Semiconductor production
• Medical devices
• Automotive components
• Aerospace applications. 

These uses are especially relevant for manufacturers managing global supply chains, as PFAS may be present deep within upstream materials or formulations.

Health and Environmental Risks

Scientific research has linked certain PFAS to a range of adverse health effects. These include increased risk of kidney and testicular cancers, liver damage, immune system suppression, thyroid disease, and reproductive and developmental harm. In addition, PFAS can interfere with hormone regulation and reduce vaccine effectiveness, which makes the chemicals especially dangerous to vulnerable populations.

From an environmental perspective, PFAS are highly mobile and bioaccumulative. They can migrate through groundwater, accumulate in plants and animals, and move up the food chain. Wildlife exposure has been documented in remote regions far from known sources, underscoring the global scale of PFAS contamination.

Communities located near manufacturing facilities, military installations, landfills, and wastewater treatment plants are often at higher risk of PFAS exposure. Workers involved in PFAS production or handling may also face elevated occupational exposure risks.

Exposure Pathways

Drinking water is the most widely recognized PFAS exposure pathway, particularly in the United States. PFAS can enter drinking water supplies through industrial discharges, firefighting foam use, and contaminated biosolids applied to agricultural land. Due to these myriad pathways, public concern about tap water safety has grown significantly.

Beyond water, PFAS exposure can occur through food, household dust, air emissions, and direct contact with consumer products. Food can become contaminated through PFAS-treated packaging, or through uptake from contaminated soil and water. Indoor environments may contain PFAS-laden dust from carpets, furniture, and treated textiles, contributing to chronic low-level exposure.

Regulatory Landscape in 2026

In recent years, PFAS regulation has accelerated at every level of government. Not all directives are the same, however, and it’s critical to distinguish between water-focused regulation and product-based regulation. Water regulations are designed to protect public health through drinking water standards and remediation requirements, while product regulations govern what can be manufactured, imported, sold, or distributed. For manufacturers, this distinction matters because much of the public conversation around “PFAS regulation” is driven by water rules that may not directly apply to their products or manufacturing processes. 

But water regulations often serve as what might be called a regulatory catalyst. They generate data, public awareness, and enforcement momentum, which regulators then use to justify tighter controls on products. As a result, manufacturers may hear extensive discussion about PFAS limits and cleanup obligations that apply primarily to water systems, while simultaneously facing separate and growing obligations tied to product disclosure, reporting, and bans. 

EPA Drinking Water Standards

In the United States, the Environmental Protection Agency (EPA) has finalized enforceable drinking water standards for several PFAS, marking a significant shift from advisory limits to legally binding requirements. These rules require routine monitoring, public disclosure, and corrective action when limits are exceeded, placing new compliance and cost pressures on public water systems.

While drinking water regulation has driven public awareness, the most complex compliance challenges for manufacturers are emerging at the product level. Unlike water systems, where PFAS sources can often be traced geographically, product-focused rules require visibility deep into global supply chains. Companies must understand not only intentionally added PFAS, but also residuals, byproducts, and processing aids used upstream.

But water regulations often serve as what might be called a regulatory catalyst. They generate data, public awareness, and enforcement momentum, which regulators then use to justify tighter controls on products.

TSCA Section 8(a)(7)

At the federal level, the EPA’s PFAS reporting rule under the Toxic Substances Control Act (TSCA) represents a foundational shift. Under TSCA Section 8(a)(7), companies that manufactured or imported PFAS or PFAS-containing articles between 2011 and 2022 must report detailed information to the EPA on each covered PFAS. Data obligations include— but are not limited to:

• Chemical identity
• Uses
• Production and processing volumes by use category. 

For many companies, these emerging obligations have triggered first-time investigations into legacy PFAS use across parts, materials, and supplier relationships. Even organizations that no longer use PFAS directly have discovered reporting obligations due to historical formulations or imported articles.

State-Level PFAS Regulations

State-level regulation is moving even faster. Minnesota has established one of the most comprehensive PFAS frameworks in the United States. The state’s PFAS reporting law requires disclosure of intentionally added PFAS in products sold in the state, with limited exemptions. This reporting obligation is paired with a phased ban on PFAS in products, culminating in a near-total prohibition by 2032 unless a use is deemed essential. Minnesota’s approach—disclosure first, ban later—has become a reference model for other states.

Other U.S. states are following similar but not identical paths. Maine, Washington, and California have implemented reporting requirements that precede category-specific bans. California has adopted PFAS prohibitions covering food packaging, juvenile products, cosmetics, and textiles, with implementation dates primarily landing between 2025 and 2028. New York, Vermont, Colorado, and Connecticut have also enacted or proposed bans targeting cookware, firefighting foams, carpets, and apparel. Across these states, a clear regulatory pattern has emerged: mandatory disclosure is often the precursor to outright prohibition.

Product-level PFAS regulation is particularly challenging because PFAS are rarely declared at the finished product level. Compliance depends on supplier engagement, material declarations, and credible data validation. In many cases, manufacturers must reconcile conflicting supplier responses, incomplete data, or claims of “unknown” PFAS content, all while facing statutory deadlines and enforcement risk.

Europe's PFAS Regulatory Proposal

Internationally, the European Union is considering one of the most far-reaching PFAS restrictions ever proposed. Under the EU’s REACH framework, regulators are evaluating a class-based restriction that would limit the manufacture, use, and sale of most PFAS, with time-limited derogations for critical applications. If adopted, this restriction would significantly affect electronics, automotive, aerospace, and industrial manufacturing sectors, forcing companies to justify PFAS use or transition to alternatives.

Beyond the EU, other jurisdictions are advancing PFAS product controls. Canada has signaled intent to regulate PFAS as a class under its chemicals management framework. Denmark and Norway have already enacted national bans on PFAS in certain consumer products, including food contact materials. And Japan and Australia continue to tighten PFAS oversight through environmental standards and chemical control programs, increasing pressure on the exporters supplying these markets.

Across these states, a clear regulatory pattern has emerged: mandatory disclosure is often the precursor to outright prohibition.

Testing and Detection

PFAS testing has evolved rapidly in response to regulatory demands. For water, standardized analytical methods such as EPA Methods 537.1, 533, and 1633 are commonly used to detect PFAS at extremely low concentrations. These methods are increasingly referenced in regulatory programs and compliance monitoring.

Product testing presents additional challenges due to complex materials and formulations. Targeted testing can identify known PFAS, while total fluorine and total organic fluorine screening methods are used to flag potential PFAS presence. Research continues to improve non-targeted analysis techniques, enabling broader detection of previously unknown PFAS.

Future Outlook

Looking ahead, PFAS regulation is expected to continue shifting toward class-based controls rather than substance-by-substance risk assessment. Scientific research is increasingly focused on mixture effects, long-term low-dose exposure, and safer alternatives. Industries are responding by investing in PFAS-free materials, redesigning products, and strengthening supply chain transparency.

For companies, PFAS in 2026 represents not only a compliance risk but also a strategic challenge that intersects with ESG goals, product design, and long-term market access. Proactive data collection and supplier engagement are becoming critical capabilities, essential to fulfilling all of these overlapping responsibilities. 

What PFAS Means for Manufacturers in 2026

For manufacturers operating in 2026, PFAS represent a convergence of regulatory risk, supply chain complexity, and long-term product strategy. While water regulations dominate headlines, it’s product-level disclosures and bans that create the most direct operational impact for manufacturers. These rules determine whether products can legally enter or remain in key markets, regardless of whether a company has any direct connection to PFAS-contaminated water.

Manufacturers are increasingly expected to understand where PFAS exist within parts, materials, and processes, even when that information resides several tiers upstream. Legacy formulations, processing aids, and imported articles can all trigger reporting or restriction obligations. At the same time, inconsistent supplier data, confidential formulations, and evolving definitions of PFAS make compliance difficult without structured data governance.

From a strategic perspective, PFAS is no longer just an environmental or toxicology issue. It intersects with ESG commitments, product design decisions, supplier qualification, and long-term market access. Companies that proactively differentiate between water-related PFAS rules and product-based obligations (and build systems to manage product-level PFAS data) are better positioned to avoid last-minute redesigns, lost sales, and regulatory enforcement as restrictions continue to expand.

PFAS FAQs 

Are PFAS Banned in the United States in 2026?

At the federal level, PFAS are not subject to a single comprehensive product ban, but enforceable drinking water standards are in place. Product bans and reporting requirements are largely driven by individual states, with timelines and covered product categories varying significantly.

Do PFAS Rules Apply to Imported Components?

In many cases, the answer is yes. State reporting laws and bans often apply to products sold into the state regardless of where they were manufactured. This means that imported parts and assemblies can trigger obligations.

Does PFAS Refer Only to PFOA and PFOS?

While PFOA and PFOS are the most well-known PFAS substances, regulators increasingly treat PFAS as a broad chemical class. This means that restrictions may apply even when specific legacy PFAS are not present.

How Can Manufacturers Determine Whether PFAS Are Present in Their Products?

This typically requires a combination of supplier disclosure, material declarations, and targeted testing—particularly as regulators move away from accepting "unknown" responses as sufficient for compliance.
