Overview
This HTS classification, 2925.29.70.00, specifically covers Tetramethylguanidine. Tetramethylguanidine (TMG) is an organic chemical compound characterized by its imine functional group. Its primary use is as a strong, non-nucleophilic base in organic synthesis, making it a valuable reagent in the production of pharmaceuticals, agrochemicals, and other fine chemicals. It is recognized for its ability to catalyze reactions and act as a proton scavenger.
Within the broader category of imine derivatives, this specific subheading distinguishes itself by its precise identification of Tetramethylguanidine. While the sibling category 2925.29.90.00 encompasses "Other" imines and their derivatives not specifically listed, this subheading provides a dedicated entry for Tetramethylguanidine, ensuring accurate tariff application for this distinct chemical. The classification recognizes the unique chemical structure and common industrial applications that set TMG apart from other imine compounds.
As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification at this level is conclusive. The tariff treatment for Tetramethylguanidine under 2925.29.70.00 is final, based on its identity as Tetramethylguanidine and its placement within the imine-function compounds.
