Microplastic Regulation: What Laws Exist and What Is Coming

The regulatory gap

No country has established legally enforceable limits on microplastic contamination in food, drinking water, or consumer products (beyond microbead bans). The WHO's 2019 review explicitly noted the absence of established safety thresholds and called for accelerated research and precautionary action²⁴. This means consumers cannot rely on regulatory standards to protect them — filtration and source reduction are currently the only available responses to individual exposure.

European Union — most advanced regulatory environment

The EU's European Chemicals Agency (ECHA) implemented in 2023 one of the most significant microplastic regulatory actions globally: a restriction on intentionally added microplastics in consumer products including cosmetics, detergents, agriculture products, and sport pitch infill. The ECHA estimates this will prevent approximately 500,000 tonnes of microplastics entering the environment over 20 years²⁵.

The EU Green Deal Chemicals Strategy aims to restrict 500 synthetic polymer types by 2030.

United Kingdom

The UK banned microbeads in rinse-off personal care products in 2018. Further single-use plastic restrictions have followed. The UK Environment Agency monitors microplastics in water bodies but has not established regulatory concentration limits.

United States

The federal Microbead-Free Waters Act (2015) banned microbeads in rinse-off personal care products. The EPA is conducting active research but has not established limits under the Safe Drinking Water Act as of 2026. California has taken the most proactive state-level approach, requiring microplastic testing of drinking water under legislation taking effect from 2024.

United Nations Global Plastics Treaty

Negotiations toward a legally binding UN Global Plastics Treaty have been ongoing since 2022 but remain incomplete as of mid-2026, with disagreements between fossil-fuel-producing nations and countries pushing for binding production caps.
