About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 2921.29.00.20, specifically covers Triethylenetetramine (TETA). TETA is an acyclic polyamine characterized by the presence of four amine groups and three ethylene bridges connecting them. It is a liquid at room temperature and is often used as an epoxy curing agent, in the production of lubricants and fuel additives, and as a chelating agent.

Within the broader classification of "Acyclic polyamines and their derivatives; salts thereof: Other," this subheading distinguishes Triethylenetetramine from its closest chemical relatives. For instance, it is differentiated from Tetraethylene pentamine (2921.29.00.10), which has a longer chain with five amine groups, and Diethylenetriamine (2921.29.00.30), which has a shorter chain with three amine groups. The "Other" category at this level (2921.29.00.55) is reserved for acyclic polyamines not specifically enumerated.

As this is a leaf node in the HTS database, there are no further subdivisions. Classification under 2921.29.00.20 is therefore determined by the precise chemical identity and purity of the imported substance, confirming it as Triethylenetetramine.
