U.S. imports of Diazo-, Azo- & Azoxy-Compounds (SITC 51485) totaled $2.5M in August 2026, imported from 16 countries.
Importers of Diazo-, Azo- & Azoxy-Compounds paid $332K in duties in August 2026, an average duty rate of 13.39% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Diazo-, Azo- & 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 dataDiazo, azo, and azoxy compounds are nitrogen-rich organic intermediates central to synthetic dye and pigment manufacturing, with azo chromophores accounting for the majority of commercial colorants used in textiles, leather, plastics, and printing inks. Certain azo dyes that cleave to release carcinogenic aromatic amines are restricted or banned in the EU and other markets, creating compliance complexity for importers supplying global supply chains. Section 301 tariffs may apply to specific compounds of Chinese origin, and importers should verify current coverage at the HTS subheading level given China's dominant role in global azo-intermediate production.

Several azo dyes and intermediates can decompose to release carcinogenic aromatic amines regulated under EU REACH and similar frameworks in other jurisdictions. US importers supplying finished goods to European or other regulated markets must verify that their azo intermediates do not appear on restricted substance lists, as downstream product rejections can occur even when US entry is unimpeded.
Azo intermediates often undergo multiple chemical transformation steps across different countries before reaching their final form. CBP's substantial transformation standard determines country of origin for duty and trade-remedy purposes; importers should work with a licensed customs broker to trace the last substantial transformation and ensure origin declarations are defensible in the event of a CBP audit.
