Northern Technologies International Corporation (NASDAQ: NTIC) develops and markets proprietary, environmentally beneficial products and services in over 65 countries through a network of wholly owned subsidiaries, majority-owned subsidiaries, joint ventures, independent distributors, and agents. The company operates through two primary reportable segments: ZERUST® corrosion prevention solutions, which generated 74.2% of consolidated net sales in fiscal 2025, and Natur-Tec® bio-based and compostable polymer resin compounds and finished products, which accounted for 25.8% of net sales.
NTIC's ZERUST® product portfolio includes plastic and paper packaging, liquids, coatings, rust removers, cleaners, diffusers, and engineered solutions designed for automotive, general industrial, mechanical, mining, agricultural, oil and gas, and retail consumer markets.
