The Southwestern United States has been a focus for a growing number of Norwegian firms that have discovered sizable industrial and consumer markets for Norwegian technology and services. At the same time, U.S.-based companies are becoming increasingly involved in Norwegian markets, with emphasis on offshore and oil-related industries.

The Southwest Chapter was formed in 1973 to aid in developing mutually beneficial cooperation between its Norwegian and American members. Its territory covers greater Houston area. The membership comprises mainly Norwegian and American companies, with the majority representing such interest as shipping and transportation, offshore engineering, oil and gas exploration and production, electronics and electrical equipment, information technology, banking, financial consulting, accounting and law.

The office of the Southwest Chapter of NACC is located at the Royal Norwegian Consulate General and the Norwegian Trade Council in Houston. The Chamber also works closely with the Greater Houston Partnership and, thus, is well placed to assist members in affairs related to Norwegian-American businesses, as well as helping new members make initial contacts in the community.
