1. Introduction
Asbestos, once hailed as a “miracle mineral” for its heat resistance and durability, has long been recognized as a potent carcinogen. Despite its known health risks, including mesothelioma, lung cancer, and asbestosis, the United States has struggled to implement a comprehensive ban on its use. While over 50 countries have fully prohibited asbestos, the U.S. only recently took significant steps to eliminate its remaining applications.
In March 2024, the Environmental Protection Agency (EPA) announced a ban on chrysotile asbestos, the last form still legally used in the U.S., primarily in automotive parts and chlorine production . This decision, decades in the making, underscores the complex interplay of industry influence, regulatory challenges, and public health advocacy that has characterized the nation’s approach to asbestos regulation.apnews.com+3time.com+3businessinsider.com+3
This article delves into the historical context, key regulatory milestones, industry dynamics, and future outlook of asbestos regulation in the U.S., providing a comprehensive overview of why a full ban took so long to materialize.
2. Background & Context
Asbestos refers to a group of naturally occurring fibrous minerals known for their strength and resistance to heat and chemicals. These properties led to widespread use in construction, automotive, and manufacturing industries throughout the 20th century. However, by the 1970s, mounting scientific evidence linked asbestos exposure to serious health issues, prompting initial regulatory actions.
In 1976, the U.S. enacted the Toxic Substances Control Act (TSCA), granting the EPA authority to regulate hazardous chemicals. Under TSCA, the EPA attempted to ban most asbestos-containing products in 1989. However, in 1991, the Fifth Circuit Court of Appeals overturned the majority of this ban, citing insufficient evidence of unreasonable risk and economic impact. This decision significantly limited the EPA’s ability to regulate asbestos, allowing its continued use in certain applications.
The 2016 amendment to TSCA aimed to strengthen chemical safety regulations, providing the EPA with enhanced authority to evaluate and manage risks. Despite this, progress remained slow, with chrysotile asbestos—the most commonly used form—still present in specific industries. It wasn’t until 2024 that the EPA finalized a rule banning its use, marking a significant shift in U.S. asbestos policy .reuters.com+1businessinsider.com+1
3. Key Highlights from the Report
1989–1991: Initial Ban and Legal Reversal
In 1989, the EPA issued a rule under TSCA to ban most asbestos-containing products. The regulation aimed to phase out asbestos use, citing health risks. However, in 1991, the Fifth Circuit Court of Appeals vacated the majority of the ban, arguing that the EPA failed to demonstrate that the ban was the least burdensome means of reducing risk. This legal setback curtailed the EPA’s regulatory reach, allowing continued use of asbestos in various products.
2016: TSCA Reform
The Frank R. Lautenberg Chemical Safety for the 21st Century Act amended TSCA in 2016, enhancing the EPA’s authority to assess and manage chemical risks. This reform mandated risk evaluations for existing chemicals, including asbestos, and removed some of the legal hurdles that had previously impeded regulation.time.com+2apnews.com+2businessinsider.com+2
2024: Comprehensive Ban on Chrysotile Asbestos
In March 2024, the EPA announced a final rule banning the use and import of chrysotile asbestos, the last form legally used in the U.S. This decision targeted its use in products like brake linings, gaskets, and chlorine production. The ban, enacted under the amended TSCA, marked a significant public health achievement and aligned with broader initiatives to reduce cancer risks .businessinsider.com+2reuters.com+2time.com+2businessinsider.com+3apnews.com+3time.com+3
Industry Influence and Regulatory Delays
Throughout the regulatory process, industry stakeholders exerted significant influence, often challenging proposed bans and regulations. Economic considerations and lobbying efforts contributed to delays in implementing comprehensive asbestos restrictions. These dynamics highlight the complex balance between public health priorities and industrial interests in chemical regulation.

Chlor-Alkali Industry
The chlor-alkali industry, which produces chlorine and sodium hydroxide, historically relied on asbestos diaphragms in its manufacturing processes. Despite the availability of alternative technologies, some facilities continued using asbestos due to cost and operational considerations. The 2024 EPA ban mandates a transition away from asbestos, with a phase-out period allowing the industry to adapt .businessinsider.com+1reuters.com+1
Automotive Sector
Asbestos-containing materials were commonly used in automotive components like brake pads and clutches due to their heat resistance. While many manufacturers phased out asbestos, some aftermarket products still contained chrysotile asbestos. The 2024 ban prohibits the import and use of such products, prompting the industry to fully transition to safer alternatives.
Construction and Building Materials
Asbestos was extensively used in construction materials, including insulation, roofing, and flooring. Although new uses have declined, existing buildings still contain asbestos, posing risks during renovations or demolitions. The EPA’s ban does not retroactively address these materials, but it underscores the importance of proper management and abatement practices.
5. Strategic Takeaways for Buyers
For industries and consumers, the 2024 asbestos ban necessitates strategic adjustments:
- Compliance Planning: Industries must assess their supply chains to identify and replace asbestos-containing materials, ensuring compliance with the new regulations.
- Worker Safety: Companies should implement training and safety programs for workers handling legacy asbestos materials to reduce occupational exposure risks (OSHA Asbestos Standards).
- Vendor Reevaluation: Businesses must reevaluate their vendors to ensure all sourced products are asbestos-free and certified under new EPA compliance standards.
- Consumer Awareness: Homeowners and consumers should be educated about asbestos-containing materials in older homes and seek licensed abatement professionals during renovations (EPA Guide to Asbestos in the Home).
These strategic shifts are not just regulatory necessities but also critical steps toward improving health outcomes and reducing long-term liability.
6. Future Outlook or Market Trends
The full ban on chrysotile asbestos in 2024 signals a pivotal shift in U.S. chemical safety regulations. Future trends suggest a growing emphasis on:
- Expanded Chemical Evaluations: Following asbestos, the EPA is expected to fast-track assessments of other legacy hazardous chemicals under TSCA, including PFAS and formaldehyde (EPA TSCA Work Plan).
- Stronger Global Alignment: With the U.S. finally banning chrysotile asbestos, it joins many industrialized nations in adopting a stricter stance on carcinogenic substances. This may encourage further harmonization with global chemical safety protocols, including those from the EU and Canada.
- Increased Litigation and Claims: As awareness grows and regulations tighten, litigation related to historical asbestos exposure may continue to rise. Law firms and insurers are likely to adapt their services to handle these claims more efficiently (CDC – Asbestos-Related Disease Statistics).
- Innovation in Safer Alternatives: The market is likely to see accelerated development and adoption of asbestos-free technologies in manufacturing, construction, and automotive industries.
Overall, the U.S. asbestos policy is transitioning from a reactive to a more proactive model. These market trends indicate a future where safety, transparency, and regulatory enforcement are paramount.
7. Conclusion + Call to Action
The decades-long struggle to ban asbestos in the United States illustrates the complex interplay of science, industry, and policy. While the 2024 EPA ban on chrysotile asbestos marks significant progress, it also serves as a reminder of the delays that allowed thousands of preventable illnesses and deaths. Industries and consumers alike must now adapt quickly, ensuring compliance and prioritizing safety.
Asbestos regulation is no longer just a legal requirement—it’s a moral and public health imperative.
