The TSCA requires manufacturers to submit premanufacture notices for new chemical substances, including additives like carbolic acid, before they can be introduced into commerce. The EPA evaluates these substances for potential risks to human health and the environment.

The European Union's REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) regulation is another significant framework that affects the use of chemical additives. Under REACH, manufacturers and importers must register substances produced or imported in quantities of one tonne or more per year. Carbolic acid, being a potential additive in wear-resistant coatings, would fall under this requirement.

In Asia, countries like China and Japan have their own regulatory systems. China's Measures for Environmental Management of New Chemical Substances and Japan's Chemical Substances Control Law both require notification and risk assessment of new chemical substances before they can be manufactured or imported.

Specific to coatings, many countries have regulations limiting the volatile organic compound (VOC) content in paints and coatings. These regulations indirectly impact the choice of additives, as manufacturers must ensure that the inclusion of carbolic acid does not compromise compliance with VOC limits.

Occupational safety regulations also play a significant role in the use of chemical additives. In the United States, the Occupational Safety and Health Administration (OSHA) sets permissible exposure limits for various chemicals, including carbolic acid, in workplace environments. Similar regulations exist in other countries, such as the Control of Substances Hazardous to Health (COSHH) Regulations in the UK.

As research on carbolic acid as a wear-resistant coatings additive progresses, it is crucial to consider these regulatory frameworks.
