PFAS Regulations United States

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) are a group of chemicals that are added to certain consumer products to enhance their ability to resist water, stains, and flames. Examples of these products include non-stick cookware, apparel, furniture, and building materials.

In recent years, PFAS have been regulated by some federal and state regulations in the US for their toxicity to humans and the environment. In this article, we introduce PFAS regulations in the US.

What are PFAS, PFOA and PFOS?

PFAS are a group of man-made chemicals that are defined as containing at least one fully fluorinated methyl or methylene carbon atom. It is estimated that there are more than 4,700 types of PFAS.

PFASs are referred to as “forever chemicals” because their carbon-fluorine bond is extremely strong and stable and makes them hard to break down and decompose.

In particular, PFOA (Perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid), which belong to the PFAS group, have been widely used in the consumer product industry since the 1940s for their properties of enhancing products’ ability to resist oil, water, flame, and chemical corrosion.

Since the 2000s, some states in the United States have restricted the use of PFAS in certain consumer products for their toxicity to human beings, wildlife, and pollution to drinking water and the natural environment.

Which products and materials may contain PFAS?

In this section, we list products and materials that may contain Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS).

Food Packaging

PFAS was firstly used in the food packaging industry in the 1960s in the United States. PFAS in food packaging excels in keeping oil and moisture oozing from food such as bakery, deli, or other cooked food.

Examples of grease-resistant food packaging that might contain PFAS include:

  • Fast food containers
  • Paper wrappers
  • popcorn bags
  • Pizza boxes
  • Pet food bags

Non-stick Kitchenware

PTFE (polytetrafluoroethylene) is one member of the 4,700 types of PFAS, and it is typically used in non-stick cookware. Examples of the non-stick cookware that might contain PTFE are:

  • Frying pans
  • Grill pans
  • Pots
  • Spatulas
  • Spoons

Opinions on the toxicity of PTFE to human beings from non-sticks are unsettled. However, some studies show that non-stick cookware processed with PTFE could release toxic fumes into the air when heated to above 250°C.

The toxic fumes can cause flu-like symptoms in human beings, which are known as polymer fume fever. Users who inhale the fumes could experience chills, fever, headache, and body aches.

Furniture and Rugs

PFAS are used in the coating materials by the furniture and carpet industry, as a method to enhance the stain and water resistance ability of these products. Here we list some examples of products that might contain PFAS::

Water-Resistant Apparel

Fabrics and textiles that are treated with PFAS have outstanding ability in resisting stains and water. Examples of clothing that may contain PFAS include:

  • Gore-Tex outdoor clothing
  • Raincoat
  • Menstruation panties
  • Hiking boots
  • Camping tents

Firefighting Foam

PFAS are commonly found in Class B firefighting foams, which are used commercially to put out the fire or used in fire training in the following establishments:

  • Military installations
  • Civilian facilities
  • Airports
  • Petroleum refineries
  • Chemical storage facilities
  • Chemical manufacturing plants


Paints and coating materials of some construction materials might contain PFAS. The active ingredient of PFAS improves the glossiness of the paint and decreases bubbling and peeling on the paint surface. PFAS also enhances the stain and water resistance of the paint.

Below are examples of products that might contain PFAS-treated paints:

PFAS Lab Testing

Third-party lab testing is often necessary to determine if a certain material contains PFAS. The testing process can also determine whether the PFAS content is above or below a certain limit, which in turn may correspond to the regulations listed in this guide.

21 CFR (FDA) – Food Contact Materials

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) are regulated by the FDA in food contact products. Only PFAS that are authorized by the FDA can be used in food contact materials. Currently, the FDA does not set maximum allowed limits on PFAS in food contact products.

Product Scope

The FDA authorized the use of PFAS in the following food contact products:

  • Non-stick cookware
  • Gaskets and O-Rings
  • Processing aids for food contact polymers
  • Paperboard or paper food packaging

Authorized Substances

The FDA has authorized the use of several types of PFAS in some categories of food contact products after reviewing the current data on their properties, health concerns, and other safety information.

According to its website, PFAS-containing coating materials in food contact products are deemed to have “negligible amount of PFAS capable of migrating to food” and PFAS used in the manufacturing of gaskets used to come into contact with food “does not pose a safety risk because they are also made of molecules that are polymerized.”

PFAS that are authorized to be used in food contact materials mainly have the following applications:

a. Coating materials of the non-stick cookware

b. Materials that are used to produce certain parts in food processing equipment that require chemical and physical durability, such as gaskets and O-Rings

c. Processing aids for manufacturing food contact polymers to reduce build-up on manufacturing equipment

d. Grease-proofing agents in paper and paperboard food packaging

Substances Notification

As explained in the previous section, the FDA authorizes the use of PFAS in certain food contact materials. However, companies selling food contact products containing PFAS must submit to the FDA a food contact substance notification, which must contain sufficient information to demonstrate that the substance is safe for the intended use.

S.3169 – Keep Food Containers Safe from PFAS Act of 2021

Even though PFAS have been authorized until now in some food contact products, there has been a growing concern about their impact on human health. In November 2021, a new bill S.3169 was introduced to Congress. The bill proposes to amend the Federal Food, Drug, and Cosmetic Act (FDCA) to prohibit the use of food packaging containing intentionally added PFAS.

Once S.3169 is passed as a law, it should be executed in all states in the United States, which will affect manufacturers, importers, or sellers of food packaging materials.

Emergency Planning and Community Right-to-Know Act (EPCRA)

The Emergency Planning and Community Right-to-Know Act (EPCRA) was created by the Environmental Protection Agency (EPA) to allow communities to plan for chemical emergencies, and it requires reporting on the use and storage of hazardous substances.

Some PFAS are listed in the Toxics Release Inventory (TRI) published under the EPCRA, including the following:

  • Perfluorooctyl iodide
  • Potassium perfluorooctanoate
  • Silver(I) perfluorooctanoate

Reporting and Recordkeeping

Manufacturers and processors of PFAS or other chemicals listed on EPCRA Section 313 are be required to report the use of the substances to the EPA, if:

a. They manufacture or process any listed chemical in an amount above a certain threshold, over a calendar year (e.g. 100 pounds for each PFAS)

b. Their facility employs 10 or more full-time employees

A wide range of facilities from multiple industries may be affected by TRI’s PFAS reporting rules. The EPA lists the industries that could be affected, which includes:

  • Food manufacturing
  • Beverage manufacturing
  • Fabric manufacturing
  • Textile manufacturing
  • Apparel manufacturing
  • Leathery goods manufacturing
  • Wood product manufacturing
  • Paper product manufacturing

Note that this is not an inclusive list. If you want to know what other industries are covered in the TRI Program, you can visit this website.

Manufacturers should also keep records of information such as the following:

  • Previous reports
  • Threshold worksheets
  • Engineering calculations and other relevant information
  • Purchase records
  • Inventory data

California Proposition 65

California Proposition 65 applies to most consumer products. This regulation sets up substance restrictions and warning label requirements for manufacturers, importers, or sellers placing their products in California in order to protect the people of California from harm caused by exposure to certain types of chemical substances.

California Proposition 65 added several PFAS to the list of chemicals known to cause reproductive toxicity to humans, including PFOA and PFOS.

Product Scope

California Proposition 65 applies to most consumer products, including the following products, which might be PFAS-treated:

  • Water/stain-resistant apparels
