When Was Asbestos Outlawed?

Early United States Regulatory Bans: 1970 to 1978

The legal framework governing asbestos began shifting dramatically in the early 1970s following mounting medical and epidemiological evidence documenting widespread mesothelioma and asbestosis among industrial workers. In 1970, Congress established the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA), prioritizing asbestos as a primary occupational and environmental hazard. In 1973, under the National Emission Standards for Hazardous Air Pollutants (NESHAP) provisions of the Clean Air Act, the EPA enacted its first historic ban, outlawing the spray application of asbestos-containing materials containing more than one percent asbestos on buildings and structural steel for fireproofing and insulation.

In 1975, the EPA expanded NESHAP regulations to ban the installation of pre-formed asbestos pipe lagging and boiler block insulation, ending decades of heavy industrial use in new construction mechanical rooms. Consumer protection agencies acted in parallel: in December 1977, the Consumer Product Safety Commission (CPSC) outlawed consumer patching compounds and drywall joint compounds containing respirable free-form asbestos under the Consumer Product Safety Act, followed in 1978 by an outright ban on artificial gas-log fireplace ash containing asbestos fibers, officially eliminating consumer retail sales.

The 1989 EPA Ban, 1991 Court Overturn, and Resulting Loophole

The defining turning point in American asbestos regulatory history occurred between 1989 and 1991. In July 1989, following ten years of exhaustive toxicological research, the EPA published its comprehensive Asbestos Ban and Phase-Out Rule (ABPR) under Section 6 of the Toxic Substances Control Act (TSCA). The rule aimed to systematically prohibit the manufacture, importation, processing, and distribution of virtually all commercial asbestos-containing products—including vinyl floor tiles, brake linings, roofing felts, and cement pipes—in three phased stages concluding in 1997.

However, asbestos manufacturing interests and foreign mining entities filed a major federal lawsuit challenging the regulation. In October 1991, the Fifth Circuit Court of Appeals issued its decision in Corrosion Proof Fittings v. EPA, striking down the vast majority of the ban. The court ruled that the EPA failed to demonstrate that a total ban was the 'least burdensome' regulatory alternative under the strict statutory wording of TSCA. Consequently, while products that were already banned prior to 1989 or out of production remained prohibited, dozens of legacy product categories—including automotive brakes, industrial gaskets, and chlor-alkali chemical diaphragms—remained technically legal to import and distribute.

International Bans and the Definitive 2024 EPA Prohibition

While the United States struggled through judicial paralysis during the 1990s and 2000s, other nations forged ahead with comprehensive legislative prohibitions. Iceland and Norway enacted some of the earliest full bans in the early 1980s. The United Kingdom enacted strict bans on amosite and crocidolite in 1985, extending to a complete prohibition on all forms of asbestos including chrysotile in 1999. Australia enacted a sweeping national ban in December 2003 under its Customs Regulations, and the European Union instituted an overarching ban across all member states in January 2005 under Directive 1999/77/EC.

In the United States, the legislative gridlock was finally resolved in 2016 when Congress passed the Frank R. Lautenberg Chemical Safety for the 21st Century Act, which amended TSCA by eliminating the flawed 'least burdensome' standard. The EPA immediately designated asbestos as one of the first ten high-priority chemicals for risk evaluation. On March 18, 2024, the EPA finalized its landmark rule banning the importation, processing, and commercial distribution of chrysotile asbestos, establishing mandatory phase-out deadlines for the chlor-alkali industry and closing the final chapter on fifty years of regulatory efforts.
