This article presents the study of rigid polyurethane foams based on tertiary amines as catalysts, the results of their production, their classification according to Commodity nomenclature of foreign economic activity (CNF EA) and their assignment of code numbers. The goods obtained as a result of scientific research were assigned commodity codes according to the CNF EA classification and entered into the general register. Rigid polyurethane foams were obtained based on the synthesized products, and samples of the obtained products were selected for further study.
