1,1'-Azobisformamide (AZODICARBONAMIDE)
1,1'-Azobisformamide, also known as azodicarbonamide (ADCA), is a yellow to orange-red crystalline powder used primarily as a chemical foaming agent in plastics and rubber production. It decomposes thermally to release nitrogen gas, creating foam structures in materials like PVC and EVA. This product falls under HTS 2927.00.15.00 as it is specifically named as an azo-compound in the tariff schedule.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing sulfone or sulfoxide groups
Sulfonated azo-derivatives may shift to oxygen function carboxylic acid compounds under Chapter note priorities.
If imported as formulated blowing agent mixture
Mixtures of chemical foaming agents with additives exceed pure compound scope of Chapter 29, falling under chemical preparations.
If for pharmaceutical intermediate use
If specifically prepared as intermediate for medicinal products, it may classify under other organic compounds used in pharmaceuticals.
