Synthetic indigo is specifically enumerated as Vat Blue 1 under HTS line 3204151000. Importers should confirm the Colour Index designation on the supplier's technical documentation; indigo in forms not meeting that specification may fall under a different line within 320415 or even a different heading depending on its chemical form.
Standard vat dyes are insoluble in water and require alkaline reduction before application, while solubilized vat dyes are water-soluble sulfuric acid esters of the leuco form, used mainly in printing pastes. The US schedule separates solubilized vat dyes into line 3204153000, so the physical and chemical form of the product determines which line applies.
