Standard International Trade Classification
U.S. imports of Aromatic Ketones, Ketone Alcohols, Ketone Aldehydes, Quinones & Their Derivatives (SITC 51629) totaled $38.7M in August 2026, imported from 35 countries.
Importers of Aromatic Ketones, Ketone Alcohols, Ketone Aldehydes, Quinones & Their Derivatives paid $5.5M in duties in August 2026, an average duty rate of 14.11% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Aromatic Ketones, Ketone Alcohols, Ketone Aldehydes, Quinones & Their Derivatives imports of $38.7M in August 2026 ran 25% above the year-to-date monthly average of $31.0M.
Last updated: August 2026 dataAromatic ketones — including commercially significant compounds such as benzophenone and acetophenone — along with quinones and bifunctional ketone derivatives, serve as UV stabilizers, photoinitiators, pharmaceutical intermediates, and dye precursors across multiple industries. The breadth of this grouping means that classification disputes are common: a compound's aromatic ring system, the presence of a secondary oxygen function (alcohol, aldehyde, or phenol), and any halogenation or sulfonation all determine the precise subheading. Several aromatic ketone derivatives used in plastics and coatings have faced antidumping or Section 301 scrutiny depending on origin, making supplier documentation particularly important.

An aromatic ketone contains at least one benzene or other aromatic ring directly attached to the carbonyl carbon, whereas cyclanic ketones have a saturated alicyclic ring. This structural distinction is the primary classification criterion between these two headings, and importers should provide structural formulas or CAS numbers to support the correct determination.
Certain quinone-based dye intermediates and aromatic ketone derivatives originating from China have been subject to antidumping duty orders or Section 301 tariffs. Importers should check the current CBP antidumping case reference file and the USTR Section 301 product list against the specific 10-digit HTS subheading before entry, as coverage varies by compound.
