Consumer Product Testing Services - TSCA Section

The Toxic Substances Control Act (TSCA) is a US law passed by the 94th US Congress in 1976 and managed by the US Environmental Protection Agency (EPA). The law regulates chemicals that are not regulated by other US federal regulations, including those already in commerce and the introduction of new chemicals.

 

According to the requirements of the Toxic Substances Control Act (TSCA), the US Environmental Protection Agency issued five final rules on January 6, 2021 to reduce exposure to certain persistent, bioaccumulation, and toxic chemicals (PBTs). The five final rules impose restrictions on decabromodiphenyl ether (decaBDE), isopropyltriphenyl phosphate (PIP (3:1)), 2,4,6-tert-butylphenol (2,4,6-tTTBP), pentachlorothiophenol (PCTP), and hexachlorobutadiene (HCBD). These chemicals will accumulate in the environment over time, which may pose potential risks to the exposed population. The above rules will come into effect on February 5, 2021 and will be implemented step by step from March 8.

 

The Toxic Substances Control Act (TSCA) is a law passed in the United States in 1976 aimed at regulating the production, use, and disposal of chemical substances to protect human health and the environment. The following is a detailed explanation about TSCA:

 

1. Overview of TSCA
Full name: Toxic Substances Control Act.

Passed in 1976 by the 94th United States Congress.

Regulatory agency: United States Environmental Protection Agency (EPA).

Purpose: To regulate chemical substances that are not subject to other federal regulations, including existing and new chemicals.

 

2. Main requirements of TSCA
(1) Regulation of existing chemical substances
Chemical Inventory: TSCA requires EPA to maintain an existing TSCA Inventory, which currently includes over 80000 chemical substances.

Risk assessment: EPA conducts a risk assessment of existing chemical substances to determine their potential hazards to human health and the environment.

Restrictive measures: Adopt restrictive measures on high-risk chemical substances, including prohibiting or restricting their production, use, and disposal.

(2) Regulation of new chemical substances
Pre Production Notification (PMN): Manufacturers or importers are required to submit a pre production notification to EPA before introducing new chemical substances.

Risk assessment: EPA conducts a risk assessment of new chemical substances to determine whether they pose a risk to human health and the environment.

Approval process: EPA decides whether to approve the production and use of new chemical substances based on risk assessment results.

(3) Information collection and reporting
Chemical Data Reporting (CDR): Manufacturers and importers are required to regularly report information on the production, use, and exposure of chemical substances to the EPA.

Health and safety research: Companies are required to submit health and safety research data on chemical substances.

 

3. 2021 PBT Chemical Restriction Rules
On January 6, 2021, the EPA issued five final rules based on TSCA, restricting the use of the following five persistent, bioaccumulative, and toxic (PBT) chemicals:

(1) DecaBDE (decabromodiphenyl ether)
Usage: Flame retardant, used for electronic devices, textiles, and building materials.

Restriction: Production, import, and sale are prohibited, except for specific purposes.

(2) Isopropylated triphenyl phosphate (PIP (3:1))
Usage: Flame retardant and plasticizer, used for plastic and rubber products.

Restriction: Production, import, and sale are prohibited, except for specific purposes.

(3) 2,4,6-tert-butylphenol (2,4,6-tTTBP)
Usage: Antioxidant, used for fuel and lubricating oil.

Restriction: Prohibited from use in lubricating oil and fuel additives.

(4) Pentachlorophenylthiophenol (PCTP)
Usage: Rubber additive, used for tires and rubber products.

Restriction: Production, import, and sale are prohibited, except for specific purposes.

(5) Hexachlorobutadiene (HCBD)
Usage: Solvent and chemical intermediate.

Restriction: Production, import, and sale are prohibited, except for specific purposes.

 

4. Implementation time
Effective date: February 5th, 2021.

Step by step implementation: gradually implemented from March 8, 2021.

 

5. Corporate Responsibility
(1) Compliance testing
Detect the content of PBT chemical substances in the product through chemical analysis.

Ensure that the product meets TSCA requirements.

(2) Technical documents
Prepare complete technical documents, including test reports, material lists, usage instructions, etc.

Ensure that the product meets TSCA requirements.

(3) Labels and identification
If the product contains PBT chemicals, relevant information must be indicated on the label.

Provide instructions for use, including applicable conditions, safety precautions, etc.

(4) Supply Chain Management
Convey relevant information about PBT chemicals downstream in the supply chain.

Ensure that the raw materials provided by suppliers comply with TSCA requirements.

 

6. Punishment and Legal Responsibility
If the product does not meet TSCA requirements, it may face penalties such as fines, product recalls, or market bans.

Manufacturers and importers are legally responsible for product compliance.

 

7. Summary
TSCA is an important law in the United States that regulates chemical substances, aimed at protecting human health and the environment. The five final rules released in 2021 further restrict the use of several PBT chemicals. Enterprises need to closely monitor TSCA requirements, fulfill compliance testing, technical document preparation, and supply chain management responsibilities to ensure that products comply with TSCA requirements and avoid legal risks.
