U.S. imports of basic dyes and preparations based thereon (HS 320413) totaled $2.3M in April 2026, traded with 16 countries.
Last updated: April 2026 dataBasic dyes carry a positive ionic charge that bonds strongly to acrylic fibers, wool, and silk, making them a workhorse colorant class for the textile and paper industries. The US tariff schedule subdivides this heading into named Colour Index designations — including Basic Black 7, Basic Orange 22, and Basic Blue 3 — as well as a residual NESOI line (3204138000), with certain lines enumerated under Additional U.S. Note 3 to Section VI carrying distinct duty treatment. India is the dominant supplier, followed by Mexico and Germany, reflecting the concentration of synthetic dye manufacturing capacity in South Asia and Europe.

Additional U.S. Note 3 to Section VI establishes a list of specific Colour Index dye numbers that must be classified under designated tariff lines rather than the NESOI catch-all. Importers should verify the exact CI number of their product against the note before filing an entry, as misclassification between a named line and the NESOI line can affect the applicable duty rate.
CBP generally expects a technical data sheet or certificate of analysis showing the active dye content and any carrier, diluent, or auxiliary substances present. A product with significant non-dye components (e.g., dispersing agents, standardizing agents) may be classified as a preparation rather than the pure dye, which can affect the applicable tariff line within 320413.
