PIP (3:1) is one of the common chemical restricted in the USA at the federal level, per TSCA.

What is the Toxic Substances Control Act (TSCA)?

The Toxic Substances Control Act (TSCA) is a law in the United States, which regulates the presence of certain chemicals, including POP (3:1). The section 6 (h) specifically addresses the use of chemicals that are persistent, bioaccumulation, and toxic (PBT):

  • PIP (3:1)
  • DecaBDE
  • 2,4,6 TTBP
  • HCBD
  • PCTP

What is PIP (3:1)?

PIP (3:1), Phenol, isopropylated, phosphate (3:1)

This chemical stands for phenol, isopropylated, phosphate (3:1). It has a multitude of functions and can be employed for different applications. Its versatile nature makes it one of the most important chemicals out of the five listed above. The table below illustrates some of the products containing PIP.

Type of Applications (Examples)
Epoxy resin
Flame retardant
Polyurethane Foam

Why is PIP (3:1) Considered Hazardous?

PIP requires special regulation due to its hazardous nature. It represents a significant danger to the aquatic life:

  • Aquatic plants;
  • Aquatic invertebrates;
  • Fish.

Moreover, research shows that that PIP can have negative consequences on organs such as the liver and the lungs. 

What Restrictions Apply to PIP (3:1)?

A series of restrictions have been announced by the United States Environmental Protection Agency (EPA) concerning the use of PIP:

  • On the 6th of January 2021, EPA announced the ban of processing and distributing this hazardous chemical in products, excluding the exceptions specified. This would be in effect as of the 31st of October 2024.
  • Effective October 31, 2023, this chemical is prohibited from being discharged in water. Manufacturers working with this molecule must demonstrate proper disposal of the substance for up to three years. This can be shown through lading bills and invoices.
  • As of the 6th of January 2025, EPA bans the presence of the substance in adhesives and sealants. Adhesives and sealants containing PIP (3:1) are therefore targeted. However, it should be noted that this restriction does not apply in the cases where it is an intermediate substance used to make cyanoacrylate adhesives.

The intention of these restrictions is to eventually end the manufacturing and distribution of articles with PIP (3:1).

What is the “No Action Assurance” by the EPA?

On March 8, 2021, EPA explained its intention not to fully enforce the restrictions mentioned above for a period of 180 days, which ends on September 4, 2021. EPA uses this period to review its restrictions concerning the five PBT substances. 

How Can Companies Comply with the TSCA PBT Final Rule for PIP (3:1)?

Despite the 180-day period, manufacturers and distributors of this chemical must make certain changes to comply with the final rule:

  • All manufacturers of articles with PIP (3:1), which are used as of March 8, 2021, must provide a written warning concerning the prohibition on manufacturing and releases to water.
  • As of July 6, 2021, those who process and distribute products containing PIP (3:1) must provide a written notification to the person receiving the shipment about the prohibition on manufacturing and releases to water.

As of the 7th of July, 2021, the written notification can be completed in one of 2 ways:

  1. Addressing the issue on the Safety Data Sheet (SDS);
  2. Placing a label on the articles with the applicable text.

Please note that medical devices, regulated under FDA, are excluded from the scope.

How Can Enviropass Help You with the TSCA PBT Prohibitions in Articles?

Enviropass suggests companies potentially affected by the new rule to use its EPEC form. This Enviropass Product Environmental Compliance (EPEC) form allows the collection of information needed to assess whether the articles handled contain PIP (3:1), and other restricted substances under RoHS, REACH-SVHC, California Prop. 65, and  more!
