The State of California's Proposition 65 requires businesses to provide a clear and reasonable warning before knowingly and intentionally exposing anyone to a listed chemical, unless the business can show that the anticipated exposure level will not pose a significant risk of cancer or is significantly below levels observed to cause birth defects or other reproductive harm.
The State of California also states this exemption:
In compliance with the State of California's Proposition 65, because my company has fewer than 10 employees, I am exempt from labeling my products.
