Vat Brown 3 Dye Powder from Japan
Vat Brown 3 is a synthetic organic vat dye used primarily for dyeing cotton, rayon, and other cellulosic fibers in textile manufacturing. It is applied in its water-insoluble form and reduced to a leuco state for dyeing, then oxidized back to its insoluble pigment form, classifying it under HTS 3204.15.20.00 as a specific vat dye.

Import Tips
• Verify the dye's chemical identity via Certificate of Analysis to confirm it matches Vat Brown 3 (C.I. 71000) for proper HTS classification
• Include Safety Data Sheets (SDS) and purity certificates; ensure packaging prevents moisture absorption as vat dyes are sensitive
• Avoid misclassification as disperse dyes; common pitfall is incorrect solubility testing—vat dyes must demonstrate vatting behavior
