Why California specifications run longer than most
A carton leaving for a California retailer usually has to carry more printed information than the same carton going anywhere else. Proposition 65 warnings, cannabis compliance panels, CalRecycle labelling rules and the ingredient disclosure that beauty buyers now expect all compete for the same panel area, and they arrive late in the process when the artwork is already laid out.
The practical consequence is that dieline planning matters more here. We would rather know at quoting that a Prop 65 panel is coming than reflow a finished layout, so tell us which disclosures apply before we cut the structural die.
