TPCH Testing Certification

TPCH is designed to reduce the content of four heavy metals (mercury, lead, cadmium and hexavalent chromium) in product packaging and packaging ingredients sold or distributed in various states in the United States. Therefore, TPCH restricts the entire packaging supply chain, including manufacturers of packaging and packaging components, suppliers, and manufacturers or distributors of products that use the packaging.
This regulation stipulates that the sum of the four heavy metals Pb, Cd, Hg, and Cr6+ in the packaging must be less than 100 ppm.
