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 box. But it is the reason the EPA has the authority to investigate and potentially restrict the 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 in consumer products, including the PTFE 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. 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 - 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 and cookware 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 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 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 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 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, 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, cookware, and water filters, 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, third-party certifications like UL Listed and 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.
