Flexible Solutions International (NYSE American: FSI) is a specialty chemicals company that manufactures and sells biodegradable polymers, energy and water conservation chemicals, nitrogen conservation products, and food-grade nutritional materials. Revenue comes from transactional product sales across four product lines: energy and water conservation products (EWCP/HEATSAVR and WATERSAVR), thermal polyaspartate biodegradable polymers (TPAs), nitrogen conservation products for agriculture, and custom food and nutritional materials produced for specific clients. FSI competes primarily against Lanxess AG in the TPA segment, where the two companies hold cross-licensed patents and are believed to have approximately equal production capacity and product costs as of the FY2025 10-K filing. The company operates through subsidiaries including NanoChem Solutions and Pana Chem Solutions Inc., which established a Panama manufacturing facility that began shipments in January 2026. FSI sells nitrogen conservation products through distributors in North and South America under trade names and private labels.
