Last updated: July 2026 dataAromatic ketones lacking additional oxygen-bearing functional groups are split at the US 10-digit level between the musk fragrance compound 7-acetyl-1,1,3,4,4,6-hexamethyltetrahydronaphthalene (2914391000) — commercially known as Tonalide or AHTN — and all other aromatic ketones (2914399000). China and India are the leading US suppliers across this heading, with France also a notable source reflecting its fragrance industry. Acetophenone, benzophenone, and related UV-absorber intermediates fall into the residual line, making precise chemical identification essential for correct classification and any applicable Section 301 duty assessment on Chinese-origin shipments.

AHTN (2914391000) is specifically enumerated because of its commercial significance as a polycyclic musk fragrance and its distinct regulatory profile — it has been subject to environmental scrutiny in various jurisdictions. Enumerating it separately allows for targeted trade monitoring and, where applicable, trade-remedy tracking distinct from other aromatic ketones.
Many chemical products originating in China, including aromatic ketones classified under Chapter 29, may be subject to Section 301 tariffs. Importers should verify the current Section 301 list coverage for the specific 10-digit HTS line before entry, as applicability and rates can change.
