U.S. imports of diazo-, azo-, or azoxy-compounds (HS 292700) totaled $2.5M in August 2026, imported from 16 countries.
Importers of Diazo-, Azo-, or Azoxy-Compounds paid $332K in duties in August 2026, an effective tariff rate of 13.39% of the $2.5M imported — duty actually collected as a share of that value, not the published tariff schedule. Diazo-, Azo-, or Azoxy-Compounds imports of $2.5M in August 2026 ran 13% below the year-to-date monthly average of $2.8M.
Last updated: August 2026 dataAzo and diazo compounds are foundational intermediates for dye manufacturing, photochemical systems, and blowing agents — end-uses that are directly reflected in the US schedule's dedicated lines for photochemicals (2927002500), fast-color bases (2927003000), and azo-sulfonic acid salts used in textile dyes. Indonesia leads US imports under this heading, followed by Japan and Mexico. Several aromatic azo compounds are subject to scrutiny under EPA TSCA and, in textile applications, under CPSC regulations governing azo dyes that can cleave to carcinogenic amines.

1,1-Azobisformamide, commonly known as azodicarbonamide (ADA), is used as a chemical blowing agent in plastics and rubber foaming. While not a food-contact substance in the US in the same way it is regulated in the EU, importers should verify TSCA inventory status and any applicable CPSC guidance if the material is destined for consumer-product applications.
Classification depends on the compound's primary commercial end-use as documented by the manufacturer. Photosensitive diazonium salts used in reprographic or lithographic applications go to 2927002500, while azo compounds sold as coupling components or bases for on-fiber dyeing fall under 2927003000. End-use certificates or manufacturer's declarations are typically required to support the claimed classification.
