Brazil CONAMA Initiates Public Consultation to Revise Battery Heavy Metal Limits Resolution 401/2008

Brazil's National Environmental Council (CONAMA) has initiated a comprehensive revision of Resolution 401/2008, which establishes heavy metal limits in batteries and environmental controls. Originally published in the Diário Oficial da União on November 5, 2008, the resolution currently establishes maximum limits for lead, cadmium, and mercury in batteries sold in Brazil, along with management standards. The revision aims to align with EU Battery Regulation standards and address emerging battery technologies including lithium-ion and solid-state batteries. This represents the first comprehensive update to Brazil's battery heavy metal framework since the original 2008 publication, reflecting significant technological developments in battery manufacturing over the past fifteen years.

The public consultation process launched in June 2023 specifically targets alignment with EU Battery Regulation standards and incorporation of requirements for new battery technologies. The current CONAMA Resolution 401/2008 operates under Brazil's National Environmental Policy framework, administered by the Ministry of Environment through CONAMA. The resolution establishes mandatory heavy metal concentration limits and requires compliance with waste management protocols for battery manufacturers and importers operating in Brazilian markets. The revision affects all battery manufacturers, importers, and distributors operating in Brazil, with companies producing or importing lithium-ion batteries, solid-state batteries, and traditional battery technologies needing to prepare for updated heavy metal limits and potentially new environmental control requirements.

Based on the consultation scope, companies should expect updated maximum concentration limits for heavy metals in battery products. New requirements for lithium-ion and solid-state battery technologies will likely include specific testing protocols and certification procedures. Environmental management standards may be enhanced to align with EU Battery Regulation provisions. The EU Battery Regulation alignment suggests stricter standards may be implemented, requiring companies to review current battery product portfolios for compliance with existing Resolution 401/2008 heavy metal limits while assessing lithium-ion and solid-state battery products for potential impact from new requirements.

Companies should prepare technical documentation demonstrating compliance with current standards while evaluating potential changes required for EU Battery Regulation alignment. This includes reviewing current battery product portfolios for compliance with existing Resolution 401/2008 heavy metal limits and assessing lithium-ion and solid-state battery products for potential impact from new requirements. Organizations should consider engaging with industry associations to participate in the consultation process and ensure their technical and regulatory concerns are addressed in the revised framework.
