2927.00.15.00 - 1,1'-Azobisformamide

This HTS category, 2927.00.15.00, specifically classifies 1,1'-Azobisformamide. This organic compound is characterized by the presence of an azo group (-N=N-) linking two formamide moieties. Its primary use is as a blowing agent in the production of polymer foams.

It is crucial to distinguish 1,1'-Azobisformamide from its sibling categories. While all fall under the broader heading of diazo-, azo-, or azoxy-compounds, the siblings list specific, complex chemical compounds with distinct structures and applications, such as sulfonic acid derivatives or diazo-ketone esters. In contrast, 2927.00.15.00 is dedicated to a single, common blowing agent, differentiating it from the more specialized or composite chemicals listed alongside it.

As a leaf node within the HTS structure, 2927.00.15.00 does not have further subcategories. Therefore, classification within this code is straightforward, relying solely on the precise identification of the imported or exported substance as 1,1'-Azobisformamide. The presence of the azo group connecting two formamide units is the definitive characteristic for classification under this code.
