In 1944, the United States Supreme Court held that insurance was an interstate commerce subject to the federal antitrust acts. This decision had the effect of forcing the separation of IMUA's rating bureau and trade association functions. IMUA transferred its form-drafting and rating functions to the Inland Marine Insurance Bureau, which in 1971 became a part of Insurance Services Office. IMUA continued to operate solely as a trade association. In 1976 the Nationwide Marine Definition (originally published in 1933) was once again amended by the National Association of Insurance Commissioners (NAIC) and remains in place today. IMUA has been committed to legislative & regulatory advocacy on behalf of its member companies, training & education of our industry professionals and research & information dissemination. Our mission is to:
Champion the interests of the inland marine industry and foster the education and development of industry professionals.
