What is TPCH?

The Toxics in Packaging Clearinghouse (TPCH) Legislation is a United States (U.S.) legislation that calls for a reduction in the use of lead, mercury, cadmium and hexavalent chromium in packaging or packaging materials used or sold within some U.S. states. The law prohibits the intentional use of those four heavy metals during the manufacturing and distribution phases, and requires manufacturers and distributors to reduce the concentration of these chemicals in their goods or packaging to less than 100 parts per million.

Manufacturers and suppliers of packaging must be able to provide a certificate of compliance to the purchasers of their goods, as well as to state agencies and the public, upon request.
