A House bill would require clothing labels to state each item's estimated microplastic content
Rep. Mace's release lays out what the bill would require and who would write the test method.
Rep. Nancy Mace (R-S.C.) introduced the Clothing Microplastic Transparency Act of 2026 on Nov. 5. It would require any company selling clothing to disclose the estimated mass of microplastic in each item on a stamp, tag or label. The Federal Trade Commission, consulting the EPA, would have one year after enactment to issue rules, including a standard test method companies must use to estimate the content. Violations would be treated as unfair or deceptive practices under the FTC Act.
"While current labels list fiber content, they do not disclose microplastics. Our bill puts the facts on the tag," Mace said.

Mike Levin said microfibers "pose a serious threat to our waterways, oceans, and food supply and can ultimately end up in our bodies."
