Northern Technologies International Corporation (NTIC) is in the business of converting unique environmentally beneficial materials science into value added products and services for industrial and consumer applications.

Our business model of commercializing clean and green technologies in niche markets depends heavily on the talents, perseverance and integrity of both our employees and our worldwide federation of joint venture partners.

NTIC was founded in 1970 in Lino Lakes, Minnesota with its primary business in oil analyzer instruments (then known as Northern Instruments, Inc.). In 1993, Northern Instruments changed its corporate name by merging into a wholly owned subsidiary, Northern Technologies International Corporation. The company has since grown out of the oil analyzer instrument business and into a global provider of corrosion inhibiting products and corrosion control management services with sales and technical support to reach in more than 70 countries. Our management system is certified to the ISO 9001:2015 Quality Management Standard.
