Company Overview

Northern Technologies International Corporation (NTIC) is a specialty chemicals company focused on corrosion prevention, lubricant additives, and bio-based materials. The company operates primarily within the industrial chemicals, materials science, and sustainability-focused packaging industries. NTIC is best known for its proprietary ZERUST® corrosion inhibiting technologies, which are used to protect metal components during manufacturing, shipping, and storage across a wide range of industrial applications.

NTIC was founded in 1970 and initially focused on corrosion control solutions for industrial customers. Over time, the company expanded its technology platform and global reach through a network of international joint ventures and subsidiaries. In the 2010s, NTIC broadened its strategic scope by investing in bio-based and compostable polymer technologies, positioning itself at the intersection of traditional industrial materials and emerging sustainable alternatives.

Business Operations

NTIC operates through two primary business segments: ZERUST® Industrial Corrosion Solutions and Natur-Tec® Biopolymers. The ZERUST® segment generates the majority of the company’s revenue and includes corrosion inhibiting packaging, fluids, lubricants, and coatings used by customers in automotive, electronics, heavy equipment, military, and oil and gas industries. Revenue is generated through direct sales in North America and through royalty and dividend income from international joint ventures.

The Natur-Tec® segment focuses on bio-based and biodegradable polymer resins and finished products, including compostable plastics used in packaging, agriculture, and consumer goods. NTIC conducts research and development internally and leverages controlled intellectual property across its global partner network. The company maintains a capital-light model internationally, relying heavily on majority- and minority-owned joint ventures rather than wholly owned foreign manufacturing operations.

Strategic Position & Investments

NTIC’s strategy centers on leveraging proprietary chemistry and intellectual property to address corrosion-related cost reduction and sustainability-driven material substitution. The company continues to invest in research and development to enhance the performance of ZERUST® technologies and expand the application range of Natur-Tec® materials. Sustainability, regulatory compliance, and lifecycle cost reduction are core elements of its long-term strategic positioning.

The company holds equity interests in more than 60 joint venture and affiliated entities worldwide, which serve as localized manufacturers and distributors of NTIC technologies. These entities are not consolidated subsidiaries but are strategically important to NTIC’s global footprint and recurring income stream. NTIC has historically pursued organic expansion and selective technology investments rather than large-scale acquisitions, and no transformational acquisitions have been consistently identified in public disclosures.

Geographic Footprint

NTIC is headquartered in North America, with its corporate offices and primary operations located in Minnesota, United States. The company maintains direct operations in the U.S. and supports customers across domestic industrial markets. Internationally, NTIC has a significant presence across Europe, Asia-Pacific, Latin America, and parts of the Middle East through its joint venture network.

The company’s technologies are marketed and sold in more than 60 countries, giving NTIC exposure to both developed and emerging industrial economies. International operations represent a substantial portion of NTIC’s overall economic activity, primarily through royalty income, equity earnings, and technology licensing rather than direct asset ownership.

NTIC is led by a management team with long-standing tenure and deep technical and operational experience in specialty chemicals and international business development. Leadership emphasizes disciplined capital allocation, protection of intellectual property, and long-term partnerships with global affiliates.
