Overview

This HTS code, 9902.06.46, specifically classifies triethylenediamine, also known as 1,4-diazabicyclo[2.2.2]octane (CAS No. 280-57-9). This compound is a tertiary amine often used as a catalyst in the production of polyurethane foams and other polymers. Its inclusion within Chapter 99 signifies that it is subject to special or temporary tariff provisions.

Distinguishing this category from its "sibling" entries within the broader HTS structure is crucial for accurate classification. While siblings at the 01xx level, for instance, deal with live animals, this code is situated within the specialized Section XXII, which encompasses temporary legislation and modifications. Therefore, the primary distinction lies in the unique regulatory or trade policy status assigned to triethylenediamine under this specific provision, rather than its intrinsic physical characteristics or intended use compared to a commodity good.

As HTS code 9902.06.46 is a leaf node, it does not contain further subcategories. This means that any import or export of triethylenediamine meeting the conditions of this specific temporary provision would be directly classified under this code. The "provided for in subheading 2933.59.95" note indicates that this special classification is applied as a modification or alternative to its regular classification within Chapter 29, highlighting the temporary or specific nature of the tariff treatment.
