Last updated: August 2026 dataNaphthalene derived from coal tar distillation — covered by a single tariff line (2707400000) — is a white crystalline solid used primarily in the production of phthalic anhydride, moth repellents, and as a surfactant precursor. US import supply is notably concentrated, with Spain and Denmark the identified leading sources, reflecting the limited number of coal tar processing facilities operating at commercial scale in Europe. Importers handling naphthalene in bulk should be aware of its classification as a possible human carcinogen under IARC Group 2B, which may affect workplace safety and waste disposal compliance.

Naphthalene is listed on the EPA Toxic Release Inventory and is subject to CERCLA reportable quantity thresholds. Importers who release or process naphthalene above threshold quantities may have federal and state reporting obligations. DOT also classifies naphthalene as a hazardous material (UN 1334 for solid form), requiring proper labeling and packaging compliance during transport.
The key criterion is origin from coal tar or other high-temperature coal distillation. Chemically pure naphthalene produced by other routes may fall under Chapter 29. A producer's declaration or process certificate confirming coal tar distillation as the production method is the standard evidence CBP would expect if the classification is questioned.
