Under California’s Proposition 65, manufacturers of consumer products sold in California will be required to include a warning label on items containing any measurable amount of diisononyl phthalate (DINP).
Under the federally mandated Consumer Product Safety Improvement Act (CPSIA), DINP is restricted to maximum levels of 0.1% in mouthable toys and components and remains legal for use in non-mouthable toys and inaccessible components.
Companies with products containing any measureable amount of DINP are required to comply, as the law does not include a “safe harbor” level for the substance.
The California Office of Environmental Health Hazard Assessment (OEHHA) last year added DINP to Proposition 65, which requires the labeling of products containing any one of the approximately 800 chemicals of concern identified by the state.
The labeling requirement goes into effect on December 20, 2014.
