Who is TradeMark Nitrogen Corporation?

Original facility built by Southern Nitrogen Corporation, focusing on Calcium Nitrate granulation.

Southern Nitrogen merged with Kaiser Aluminum & Chemical Corporation becoming their Agricultural Chemicals Division.

Trademark Fertilizer Trading was founded in 1981 and expanded in 1983 with the acquisition of the Tampa manufacturing facility from Kaiser Aluminum & Chemical Corp., establishing the foundation for what is now TradeMark Nitrogen Corp.. Since then, the company has grown into a trusted manufacturer and distributor of nitrogen solutions serving agricultural, industrial, mining, and water treatment markets across North America.

TradeMark Nitrogen Corp. begins full-scale production of magnesium nitrate solution, helping establish the company as a leading U.S. manufacturer and supplier of specialty nitrate solutions serving industrial, agricultural, and water treatment markets.

Rick Brandt, CEO & President at BRANDT, assumes 100% ownership of TradeMark Nitrogen Corp.

TradeMark Nitrogen launches Copper Nitrate Solution production, expanding its specialty nitrate portfolio and strengthening its position as a leading U.S. manufacturer serving industrial, catalyst, electronics, metal finishing, chemical manufacturing, and agricultural markets.

Launch of CT-70® and CAL-12® Calcium Nitrate Solutions

TradeMark Nitrogen expanded its specialty fertilizer and industrial chemical portfolio in 2021 with the launch of CT-70® Calcium Nitrate Solution and CAL-12® Calcium Fertilizer. Produced in Tampa, Florida using locally sourced limestone and nitric acid, these products provide highly available calcium and nitrate nitrogen for agriculture, horticulture, fertigation, concrete admixtures, wastewater treatment, and industrial applications. The introduction of CT-70® and CAL-12® further established TradeMark Nitrogen as a trusted U.S. manufacturer of calcium nitrate and specialty nitrogen products.

Substain-N® Launch

In 2025, TradeMark Nitrogen expanded its specialty fertilizer portfolio with the introduction of Substain-N®, a premium slow-release liquid nitrogen fertilizer formulated with Urea Triazone technology. Designed for turf, ornamentals, agriculture, and professional landscape markets, Substain-N® provides extended nitrogen availability, reduced volatilization, and improved nutrient use efficiency compared to conventional nitrogen fertilizers. The product further strengthened TMN's commitment to innovative, high-performance crop nutrition solutions manufactured in Tampa, Florida.

Return to Aqua Ammonia Manufacturing

In 2026, TradeMark Nitrogen re-entered the Aqua Ammonia market after more than two decades by commissioning a new state-of-the-art production system capable of manufacturing 19.5% and 29.5% Aqua Ammonia. The investment expanded TMN's capabilities in municipal drinking water treatment, wastewater treatment, industrial processing, and chloramination applications, while supporting production to NSF/ANSI 60 requirements. This milestone reinforced TMN's position as a leading U.S. manufacturer of nitrogen-based chemical solutions.
