Nineteen U.S. states have toxics in packaging requirements, all based on the Model Toxics in Packaging Legislation. All U.S. state toxics in packaging laws have the same basic requirements – that is, no intentional use of any amount of the four restricted metals and a threshold level of 100 ppm for the total of the four metals combined.
State laws may differ from the Model, particularly for allowable exemptions and enforcement. State laws take precedence over the Model Legislation. A comparison between the Model and the laws of TPCH member states is available here.
