The Art & Creative Materials Institute, Inc. (ACMI) is an industry trade group composed of over 200 companies that manufacture art materials. ACMI's main function is to certify art and creative materials (such as paints, pencils, crayons, markers, etc.) as non-toxic. Art and creative materials that have been certified as non-toxic by ACMI are entitled to display an ACMI certification seal on their packaging. Products submitted to ACMI for certification are tested by a toxicologist to ensure they are non-toxic. ACMI also promotes art education, and was a founding member of the Council for Art Education, Inc., which promotes March as Youth Art Month. ACMI was founded in 1936 and is currently headquartered in Hanson, Massachusetts.
ACMI was initially known as the Crayon, Water Color & Craft Institute, Inc. It was renamed the Art & Craft Materials Institute in 1982. It adopted its current name in the late 2000s.
