Premanufacture Notice (PMN)

A Premanufacture Notice (PMN) is a formal notification that companies in the United States must submit to the Environmental Protection Agency (EPA) before manufacturing or importing a new chemical substance for commercial use. The purpose of the PMN is to provide the EPA with information about the chemical’s properties and potential risks so they can assess environmental and health impacts. This process helps ensure that new chemicals are used safely and regulations are followed, protecting public health and the environment. The notice typically must be submitted at least 90 days before production begins.
