# TSCA (Toxic Substances Control Act)

> The primary US federal law governing chemical safety in consumer products, enacted in 1976 and substantially reformed by the Lautenberg Chemical Safety Act of 2016. TSCA authorizes the EPA to evaluate, regulate, and restrict chemicals used in manufacturing - including the PFAS compounds found in nonstick cookware coatings.

## Reality Check

**Claim:** If a chemical is on the TSCA inventory, it has been tested and found safe
**Reality:** Being on the TSCA inventory simply means a chemical was in US commerce when the inventory was compiled or has been reviewed for market entry since. The original 1976 TSCA grandfathered in roughly 62,000 existing chemicals without safety testing. The 2016 reform requires the EPA to systematically evaluate chemicals for risk, but this process is ongoing and will take years to work through the backlog. TSCA inventory listing is a market presence indicator, not a safety certification.

## Overview

When we talk about product safety for families, we usually focus on the things we can see - labels, certifications, warning tags. But behind all of those sits a legal framework that determines which chemicals are allowed in the products we bring home. In the United States, that framework is the Toxic Substances Control Act, or TSCA.

TSCA is not a label you will find on your [air fryer](/category/air-fryer) box. But it is the reason the EPA has the authority to investigate and potentially restrict the [PFAS](/learn/ingredients/pfas) compounds used in nonstick coatings. Understanding TSCA helps you see why some chemicals are still in products and what is actually being done about it.

## What TSCA Is and What It Does

Congress passed TSCA in 1976 to give the Environmental Protection Agency authority over chemicals used in commerce. The law covers the manufacturing, processing, distribution, use, and disposal of chemical substances - essentially the full lifecycle of a chemical from factory to landfill.

TSCA maintains the TSCA Chemical Substance Inventory, a list of more than 86,000 chemicals in US commerce. Any new chemical must be reviewed by the EPA before it enters the market. For chemicals already on the inventory - the so-called "existing chemicals" - the EPA must evaluate whether they present an unreasonable risk of injury to health or the environment.

Here is the important part for families: TSCA is the legal authority under which the EPA could restrict or ban [PFAS](/learn/ingredients/pfas) in consumer products, including the [PTFE](/learn/ingredients/ptfe-teflon) coatings used in air fryer baskets and nonstick cookware. TSCA does not directly regulate the coating on your pan - that is [FDA food-contact regulation](/learn/standards/fda-food-contact-rules). But TSCA governs whether the chemical itself is allowed to be manufactured and sold in the first place.

## The 2016 Lautenberg Reform: Why It Matters

The original 1976 TSCA had a significant weakness. The EPA had to prove a chemical posed an "unreasonable risk" before it could take action, but the burden of proof was so high that the agency could not even successfully ban asbestos - a known carcinogen. A federal court overturned the EPA's asbestos ban in 1991, and the agency essentially stopped trying to restrict chemicals under TSCA for two decades.

The Frank R. Lautenberg Chemical Safety for the 21st Century Act, signed in June 2016, overhauled the law. Key changes:

**Mandatory risk evaluation.** The EPA must now systematically evaluate existing chemicals for safety rather than waiting for harm to be documented. The agency must have at least 20 chemicals under active risk evaluation at all times.

**New chemicals get real review.** Before 2016, new chemicals could enter commerce unless the EPA took action within 90 days. Now, the EPA must make an affirmative finding that a new chemical is safe before it can be manufactured.

**Risk-based standard.** The evaluation focuses on whether a chemical presents an "unreasonable risk of injury" to health or the environment. If it does, the EPA must take regulatory action - the law does not allow the agency to walk away from a finding of unreasonable risk.

**Cost is no longer a shield.** Under the old TSCA, the EPA had to use the "least burdensome" regulation. The reformed law requires the EPA to address unreasonable risk without this cost-minimization requirement.

## TSCA and PFAS: Where It Gets Real for Families

The connection between TSCA and your kitchen is [PFAS](/learn/ingredients/pfas) - the family of synthetic chemicals that includes the compounds used in nonstick coatings.

The EPA has been using its TSCA authority to increasingly scrutinize PFAS chemicals. Here is where things stand:

**PFOA and PFOS reporting rule.** In October 2023, the EPA finalized a TSCA rule requiring any entity that has manufactured or imported PFAS since 2011 to report detailed information about the chemicals - including quantities, uses, disposal, exposures, and health effects. This is the most comprehensive PFAS data collection effort in US history and covers all PFAS, not just the well-known ones.

**Significant new use rules (SNURs).** The EPA has issued SNURs under TSCA for certain long-chain PFAS, including PFOA and PFOS. A SNUR means that anyone who wants to start manufacturing or importing these chemicals for a new use must notify the EPA at least 90 days in advance. This effectively prevents these chemicals from re-entering commerce for new applications.

**Risk evaluations in progress.** The EPA has prioritized several PFAS chemicals for formal risk evaluation under TSCA's Section 6. A finding of unreasonable risk would trigger mandatory restrictions.

This matters for [air fryer](/category/air-fryer) and [cookware](/category/cookware-set) shoppers because TSCA action against specific PFAS compounds could eventually affect which nonstick coating chemicals are available to manufacturers. The [EPA's broader PFAS strategy](/learn/standards/epa-pfas-regulations) uses TSCA as one of several legal tools.

## How TSCA Differs from Other Regulations You Will See

One of the most common points of confusion is how TSCA relates to the other standards and regulations we reference in our product reviews. Here is the breakdown:

**TSCA vs. FDA food-contact rules.** TSCA governs whether a chemical can be manufactured and sold in commerce. [FDA food-contact regulations](/learn/standards/fda-food-contact-rules) govern whether a chemical can be used in materials that touch food. A chemical could be legal under TSCA (allowed in commerce) but restricted by the FDA for food-contact use. In practice, the FDA and EPA coordinate, but they operate under different legal frameworks with different standards.

**TSCA vs. Prop 65.** [California Proposition 65](/learn/standards/prop-65) requires warnings when products expose consumers to listed chemicals. TSCA can actually restrict or ban those chemicals entirely. Prop 65 is a disclosure law; TSCA is a substance control law. They work at different levels.

**TSCA vs. EU REACH.** The European Union's [REACH regulation](/learn/certifications/reach-compliant) requires manufacturers to prove chemicals are safe before they can be used. TSCA historically allowed chemicals to stay in commerce until the EPA proved they were dangerous. The 2016 reform narrowed this gap somewhat, but the EU approach remains more precautionary.

## What TSCA Does Not Cover

TSCA has specific exemptions that are important to understand. The law does not cover:

- **Pesticides** - regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
- **Food, food additives, drugs, and cosmetics** - regulated by the FDA under the Federal Food, Drug, and Cosmetic Act
- **Tobacco and tobacco products** - regulated by the FDA under the Family Smoking Prevention and Tobacco Control Act
- **Nuclear material** - regulated by the Nuclear Regulatory Commission
- **Firearms and ammunition** - exempted from TSCA

The food exemption is particularly relevant for cookware. TSCA governs the chemical itself in commerce, but once that chemical is used in a food-contact material, FDA regulation takes over for the food safety aspect. This creates a dual-authority situation where both TSCA and FDA rules apply to nonstick cookware chemicals - TSCA for the chemical's general market presence and FDA for its specific use touching food.

## The TSCA Inventory and What It Tells You

The TSCA Chemical Substance Inventory is publicly searchable. If you are researching a specific chemical in your cookware or [air fryer](/category/air-fryer), you can look it up on the EPA's CompTox Chemicals Dashboard to see whether it is on the TSCA inventory, whether it has been subject to any TSCA actions, and what data the EPA has collected.

For most families, the practical takeaway is this: if a chemical is being scrutinized under TSCA (like certain PFAS compounds), it means the EPA has identified it as a potential concern and is actively evaluating whether restrictions are warranted. That is a signal worth paying attention to - not because the chemical is automatically dangerous, but because federal regulators with access to confidential business data have determined it warrants a closer look.

## How R3 Uses TSCA in Our Evaluation

When we evaluate [air fryers](/category/air-fryer), [cookware](/category/cookware-set), and [water filters](/category/water-filter), TSCA status informs our chemical safety scoring in a specific way. If a chemical used in a product's coating or materials is under active TSCA risk evaluation, we flag it. If the EPA has issued a SNUR for that chemical, we note the restriction. If a manufacturer uses chemicals that have cleared TSCA review without findings of unreasonable risk, that is a positive data point.

We pair TSCA status with [FDA food-contact authorization](/learn/standards/fda-food-contact-rules), third-party certifications like [UL Listed](/learn/certifications/ul-listed) and [ETL Certified](/learn/certifications/etl-certified), and independent lab testing to build a complete picture. No single regulation tells the whole story - TSCA is one important piece of the framework.

## Also Known As

- Toxic Substances Control Act
- TSCA
- Lautenberg Chemical Safety Act (2016 amendment)
- 15 U.S.C. Chapter 53

## Where Found

- Referenced in EPA enforcement actions against chemical manufacturers
- Chemical safety data sheets for nonstick coating compounds used in air fryers and cookware
- EPA PFAS reporting requirements affecting manufacturers of consumer kitchen products
- Regulatory compliance documentation for imported cookware and appliances
- Environmental and health policy discussions about PFAS restrictions in consumer goods

## Health Concerns

TSCA itself is a law, not a chemical - it does not directly cause health effects. However, the chemicals TSCA regulates include substances with well-documented health concerns.

**PFAS compounds** currently under TSCA scrutiny include PFOA (classified as a Group 1 human carcinogen by the WHO in 2023), PFOS, and GenX chemicals. These are the same compounds found in some [air fryer](/category/air-fryer) nonstick coatings and are associated with cancer, thyroid disease, reproductive harm, and immune system effects.

**The regulatory gap:** Before the 2016 reform, thousands of chemicals entered US commerce without meaningful safety review. The EPA is now working through a backlog of existing chemicals, but the evaluation process takes years per chemical. This means some chemicals in current consumer products have not been fully evaluated for safety under the reformed TSCA framework.

## Regulatory Status

**TSCA (15 U.S.C. 2601-2697):**
- Enacted: October 11, 1976
- Major reform: Frank R. Lautenberg Chemical Safety for the 21st Century Act, signed June 22, 2016
- Administered by: US Environmental Protection Agency (EPA)
- TSCA Inventory: 86,000+ chemical substances
- Current PFAS actions: PFAS reporting rule finalized October 2023; SNURs issued for long-chain PFAS; multiple PFAS chemicals prioritized for risk evaluation
- Mandatory evaluation: EPA must maintain at least 20 chemicals under active risk evaluation at all times
- New chemical review: Affirmative safety finding required before new chemicals can enter commerce (post-2016)

**Relationship to other frameworks:**
- FDA food-contact regulations govern chemical use in food-contact materials (overlapping jurisdiction for cookware coatings)
- [REACH](/learn/certifications/reach-compliant) is the EU equivalent with a more precautionary approach
- [Prop 65](/learn/standards/prop-65) is California's complementary disclosure law
- [EPA PFAS regulations](/learn/standards/epa-pfas-regulations) use TSCA as one of several legal authorities

## Label Guide

**Look for:**
- Products made with chemicals that have cleared TSCA review without findings of unreasonable risk
- Manufacturers that voluntarily disclose TSCA compliance for their chemical ingredients
- PFAS-free products that avoid TSCA-scrutinized compounds entirely
- Products carrying third-party certifications (NSF, UL, ETL) that independently verify chemical safety beyond TSCA requirements

**Avoid / misleading:**
- Products containing chemicals subject to TSCA Significant New Use Rules (SNURs) without clear justification
- Cookware or air fryers using coating chemicals under active TSCA risk evaluation with no third-party safety verification
- Imported products from manufacturers that have not filed required TSCA reporting for PFAS compounds

## Who Is At Risk

- Families using nonstick cookware and air fryers with PFAS-based coatings - these chemicals are under active TSCA scrutiny for potential unreasonable risk
- Children, who are more vulnerable to chemical exposures due to developing organ systems and higher exposure-to-body-weight ratios
- Consumers relying solely on TSCA compliance as a safety indicator - TSCA inventory listing does not mean a chemical has been evaluated for safety
- Households with aging or damaged nonstick cookware where coating degradation may increase chemical migration into food

## How To Verify

Search the EPA's CompTox Chemicals Dashboard (comptox.epa.gov) to check whether a specific chemical is on the TSCA inventory and whether it has any TSCA actions. Review the EPA's TSCA Chemical Data Reporting page for industry-submitted data on chemical manufacturing volumes and uses. For PFAS specifically, check the EPA's PFAS Strategic Roadmap progress page for the latest regulatory actions under TSCA authority. Cross-reference with the manufacturer's Safety Data Sheets (SDS) for cookware coating ingredients.

## TSCA and Your Air Fryer: The PFAS Connection

The nonstick coatings on many [air fryer](/category/air-fryer) baskets use [PTFE](/learn/ingredients/ptfe-teflon), a PFAS polymer. TSCA is the federal law that gives the EPA authority to investigate and potentially restrict these PFAS compounds. While TSCA action is slow - risk evaluations take years - the EPA's October 2023 PFAS reporting rule is generating the most comprehensive dataset ever collected on PFAS manufacturing and use. If you want to get ahead of potential TSCA restrictions, choosing air fryers with ceramic or stainless steel baskets avoids the PFAS question entirely.

## What This Does Not Cover

Pesticides (regulated under FIFRA),Food, food additives, drugs, and cosmetics (regulated by FDA),Tobacco products (regulated by FDA),Nuclear materials (regulated by NRC),Firearms and ammunition (exempted),The safety of a chemical specifically as a food-contact substance - that jurisdiction belongs to the FDA,State-level chemical regulations like Prop 65 or California AB 1200, which operate independently

## R3 Bottom Line

- TSCA is the federal backbone of US chemical safety law - it gives the EPA authority to evaluate and restrict chemicals like the PFAS compounds found in nonstick air fryer coatings, but the evaluation process takes years per chemical.
- The 2016 Lautenberg reform gave TSCA real enforcement power for the first time, requiring systematic evaluation of existing chemicals and affirmative safety findings for new ones entering commerce.
- The EPA's October 2023 PFAS reporting rule under TSCA is generating unprecedented data on PFAS manufacturing and use - this data will drive future restrictions that could directly affect nonstick cookware.
- TSCA inventory listing does not mean a chemical is safe - roughly 62,000 chemicals were grandfathered in without testing in 1976, and the EPA is still working through the evaluation backlog.
- For practical purchasing decisions, look past TSCA to downstream indicators: FDA food-contact authorization, third-party certifications like UL and ETL, and manufacturer chemical disclosures under state laws like California AB 1200.

## FAQ

### What does TSCA have to do with air fryers?

TSCA is the federal law that gives the EPA authority to evaluate and restrict chemicals in consumer products. Many [air fryer](/category/air-fryer) baskets use [PTFE](/learn/ingredients/ptfe-teflon) nonstick coatings, which contain [PFAS](/learn/ingredients/pfas) compounds. The EPA is using its TSCA authority to scrutinize PFAS - including requiring comprehensive industry reporting and conducting risk evaluations. If the EPA finds PFAS compounds pose unreasonable risk under TSCA, it could restrict their manufacturing and use, which would directly affect nonstick cookware coatings.

### Is TSCA the same as FDA approval for cookware?

No. TSCA and FDA food-contact regulation are separate legal frameworks with different purposes. TSCA governs whether a chemical can be manufactured and sold in US commerce. [FDA food-contact rules](/learn/standards/fda-food-contact-rules) govern whether a chemical can be used in materials that touch food. A chemical might be legal under TSCA but restricted for food-contact use by the FDA, or vice versa. For cookware and air fryers, both frameworks apply - TSCA to the chemical's general commerce status and FDA to its specific food-contact application.

### How did the 2016 Lautenberg Act change TSCA?

The Lautenberg Chemical Safety for the 21st Century Act was a major overhaul. Before 2016, the EPA could not even successfully ban asbestos under TSCA because the burden of proof was too high. The reform required mandatory risk evaluations of existing chemicals, eliminated the 'least burdensome regulation' requirement, required affirmative safety findings for new chemicals before market entry, and mandated that the EPA maintain at least 20 chemicals under active evaluation at all times. It gave the EPA real enforcement teeth for the first time.

### Can I look up chemicals on the TSCA inventory?

Yes. The EPA's CompTox Chemicals Dashboard at comptox.epa.gov allows you to search for specific chemicals and see their TSCA inventory status, any regulatory actions, and available health and environmental data. For most families, the practical value is checking whether a specific chemical in a product's coating or material is under active TSCA scrutiny - which would indicate the EPA considers it worth investigating.

### Does TSCA actually ban any chemicals?

TSCA gives the EPA the authority to ban, restrict, or impose requirements on chemicals - but outright bans have been rare historically. The most notable failure was the EPA's attempted asbestos ban in 1989, which was overturned by a federal court in 1991. The 2016 reform strengthened the EPA's ability to take action. For PFAS specifically, the EPA is using TSCA authority for reporting requirements, significant new use rules, and risk evaluations that could lead to restrictions. The process is methodical but slow.

### How does TSCA compare to the EU's chemical safety approach?

The EU's [REACH regulation](/learn/certifications/reach-compliant) takes a more precautionary approach than TSCA. Under REACH, manufacturers must prove a chemical is safe before it enters the EU market. Under TSCA - even after the 2016 reform - chemicals already in commerce can continue to be sold while the EPA evaluates them. The EU is also moving faster on PFAS restrictions, with a proposed universal PFAS restriction under consideration. Products manufactured to EU standards generally meet stricter chemical safety requirements than US-only products.

### What is the EPA's PFAS reporting rule under TSCA?

Finalized in October 2023, the TSCA PFAS reporting rule requires any entity that has manufactured or imported PFAS since 2011 to report detailed data including chemical identity, quantities, uses, disposal methods, worker exposures, and health effects data. This covers all PFAS compounds - not just the well-known ones like PFOA and PFOS. It is the most comprehensive PFAS data collection in US history and will inform the EPA's future regulatory decisions about these chemicals in consumer products.
