U.S. imports of Halogenated Derivatives of Aromatic Hydrocarbons (NESOI) (HS 290399) totaled $10.6M in August 2026, imported from 17 countries.
Importers of Halogenated Derivatives of Aromatic Hydrocarbons (NESOI) paid $1.2M in duties in August 2026, an average duty rate of 14.83% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Halogenated Derivatives of Aromatic Hydrocarbons (NESOI) imports of $10.6M in August 2026 ran 60% above the year-to-date monthly average of $6.6M.
Last updated: August 2026 dataSpanning benzyl chloride, benzotrichloride, trichlorobenzenes, trifluorotoluene derivatives, and brominated flame retardants such as pentabromoethylbenzene (2903992300), this residual aromatic halogen heading serves as a critical intermediate supply channel for agrochemicals, pharmaceuticals, dyes, and electronics flame-retardant systems. China dominates US imports under this heading, followed by India, Germany, Japan, and Italy — a supply concentration that means Section 301 tariff exposure is a routine cost consideration for buyers sourcing from Chinese producers. The eight 10-digit lines within the heading reflect meaningful duty and end-use distinctions, making precise classification essential.

Headings 290391 and 290392 cover specifically named compounds (chlorobenzene, dichlorobenzenes, hexachlorobenzene, DDT). Any halogenated aromatic hydrocarbon derivative not described by those named headings — and not classifiable in another specific Chapter 29 provision — falls to the NESOI heading 290399. Importers should work through the GRI classification rules and, where ambiguity exists, consider a CBP binding ruling to lock in the correct 10-digit line.
Many chemical intermediates in heading 290399 sourced from China are subject to Section 301 tariffs. The applicable rate and any product exclusions depend on the specific 10-digit HTS line and the current status of USTR exclusion lists, which have changed over time. Importers should verify the Section 301 status of their specific line at the time of entry and monitor USTR notices for exclusion opportunities or expirations.
