Import Direct Black 22 — Buy in Bulk from Supplier in India

Direct Black 22, identified by C.I. 35435 and CAS 6473-13-8, is a water-soluble azo dye supplied as a fine powder by Aryan Dyes & Pigments. It is formulated for direct application on cellulosic fibers, leather, paper, and wood substrates without requiring a mordant. The product is available in packaging sizes starting at 25kg, consistent with industrial batch processing needs.

The dye exhibits moderate lightfastness and good solubility in hot water, typical of direct black dyes used in textile and leather finishing. Its chemical structure allows for deep, neutral black shades with minimal hue shift under standard dyeing conditions. Industry standards for this class generally require moisture content below 5% and foreign matter under 0.5%, though these are not certified by the supplier.

Buyers in the leather processing, paper coating, and textile dyeing sectors use this product for cost-effective black coloring where high washfastness is not critical. The supplier offers bulk quantities in polyethylene-lined bags, with standard export packaging. Lead time and incoterms must be confirmed directly, as no details are published. Buyers should request batch-specific test reports for purity and solubility before large-scale use.

Aryan Dyes & Pigments operates from Surat, Gujarat, and is listed as a harbor-tier supplier with no public response metrics. The company does not publish its founding date, workforce size, or annual turnover. Its listing confirms active production and export of direct dyes, including Direct Black 22, but provides no details on certifications, client names, or laboratory facilities.

The supplier's profile indicates a focus on bulk dye supply rather than technical support or custom formulation. There is no mention of ISO, OEKO-TEX, or REACH compliance, nor any indication of in-house testing capabilities. Buyers should treat this as a commodity supplier with limited post-sale documentation, and verify all technical claims with batch-specific data before procurement.
