Last updated: April 2026 dataAlpha-naphthol and 2-naphthol (beta-naphthol) are key aromatic intermediates for azo dye synthesis, rubber antioxidants, and pharmaceutical building blocks, and the US schedule distinguishes them at the 10-digit level: 2907151000 for alpha-naphthol and 2907153000 for beta-naphthol, with a residual line 2907150000 for other naphthols and salts. China is by far the dominant supplier, reflecting its large-scale coal-tar processing and downstream dye-intermediate industry, with India and Switzerland also contributing. Importers should be aware that Chinese-origin goods under this heading are subject to Section 301 tariffs. Purity specifications and isomer identity are critical for dye and pharmaceutical customers and should be clearly stated on certificates of analysis.

The US schedule separates them at the 10-digit level: alpha-naphthol enters under 2907151000 and 2-naphthol (beta-naphthol) under 2907153000. Correct isomer identification on the entry documentation is essential to avoid misclassification.
China's large coal-tar distillation and naphthalene processing infrastructure gives it a significant cost and scale advantage in naphthol production. However, Section 301 tariffs on Chinese-origin goods have prompted some buyers to evaluate Indian suppliers as an alternative source.
