<jats:p>In this study several new bis-thiourea derivatives based on hexamethylene bis-carbamate fragments were synthesized and their classification within the Commodity Nomenclature of Foreign Economic Activity (CNFEA 2022) was evaluated. Structural analysis shows that the compounds contain thiocarbonyl (C=S), carbamate and aromatic fragments that determine their physicochemical properties and potential functional applications. Based on the dominant organosulfur functional group and physicochemical behavior, the synthesized compounds are proposed to be classified under HS code 2930 90 9800 (other organosulfur compounds). The proposed classification may facilitate the identification of these compounds in international trade and customs practice.</jats:p>
