Standard International Trade Classification
U.S. exports of Halogenated, Sulfonated, Nitrated or Nitrosated Derivatives of Phenols and Phenol-Alcohols (SITC 51244) totaled $2.5M in August 2026.
Importers of Halogenated, Sulfonated, Nitrated or Nitrosated Derivatives of Phenols and Phenol-Alcohols paid $138K in duties in August 2026, an average duty rate of 8.48% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Halogenated, Sulfonated, Nitrated or Nitrosated Derivatives of Phenols and Phenol-Alcohols imports of $1.6M in August 2026 ran 40% below the year-to-date monthly average of $2.7M.
Last updated: August 2026 dataDerivatives of phenols and phenol-alcohols that have been halogenated, sulfonated, nitrated, or nitrosated represent a chemically reactive class used as dye intermediates, biocides, flame retardants, and agrochemical precursors — with pentachlorophenol (PCP) and triclosan among the more widely recognized members. Several halogenated phenol derivatives are subject to international restrictions under the Stockholm Convention on persistent organic pollutants, and importers must verify that the specific compound is not prohibited or restricted before shipment. The reactive nature of nitrated phenol derivatives also triggers DOT hazardous-materials classification requirements and may require advance notification to the port.

Yes — certain halogenated phenols, most notably pentachlorophenol (PCP) and its salts, are listed under the Stockholm Convention on Persistent Organic Pollutants. While the US has not ratified the Stockholm Convention, EPA regulates PCP under TSCA and FIFRA, and importers must confirm that the specific compound is not subject to an EPA import restriction or significant new use rule (SNUR) before filing entry.
Nitrated phenols such as picric acid and dinitrophenol are classified as explosive or flammable hazardous materials under DOT regulations, requiring UN-compliant packaging, hazmat shipping papers, and in some cases advance notification to the port authority. Importers should also check whether the specific nitrophenol compound appears on any DEA or DHS precursor chemical watch list before arranging shipment.
