What Mexico's Proposed Import and Export Restrictions Entail?
Mexico wants input on a plan to impose import and export limitations on two PFASs. If accepted, corporations would require a permit from several government agencies to import or export perfluorooctane sulfonate (PFOS) and its derivatives, as well as perfluorooctanoic acid (PFOA), its salts, and related substances.
The Montreal Protocol's Kigali Amendment and the Stockholm Convention's definitions of some industrial persistent organic pollutants (POPs) are also referenced in the proposed list of compounds. Particularly, imports of specific POPs, such as PFOS and PFOA, and hydrofluorocarbons (HFCs) would now need special permissions.
How Mexico Plans to Regulate PFASs: Permit Requirements and Regulatory Framework?
With Brazil and Argentina passing laws prohibiting or outlawing the use of ozone-depleting compounds, other nations in Latin America have usually placed bans or specified usage limits on substances covered by international treaties. But rather than imposing restrictions, Mexico has chosen to demand import permits.
The National Institute of Ecology and Climate Change and the environment ministry's most recent data show that between 2010 and 2015, Mexico imported more than 900 kg of PFOS with a market value of over US$7.7 million.
Why Mexico Is Implementing Import Restrictions: Environmental and Public Health Concerns
On February 10, 2003, Mexico approved the Stockholm Convention. At the time of its implementation on May 17, 2004, it was the first Latin American nation to do so. The deadline for stakeholders to submit their opinions on the draught list is not specified in the comments site, and an inquiry to Mexico's environment ministry before publishing received no response.
