Direct Black 80 is a synthetic azo dye with the chemical formula C36H23N8Na3O11S3 and CAS number 8003-69-8. It is supplied as a fine powder with a deep black hue and is primarily used for dyeing leather and paper substrates. The product is manufactured in Gujarat, India, and is identified by its EINECS number 232-322-4. The supplier lists no additional purity or particle size data.
This dye belongs to the direct dye class, meaning it bonds directly to cellulose and protein fibers without requiring a mordant. It is typical for such dyes to have moderate lightfastness and washfastness, suitable for interior-grade leather and low-usage paper products. The molecular structure contains multiple sulfonate groups, which enhance water solubility and reduce aggregation during application.
Buyers include tanneries producing footwear and upholstery leather, as well as paper manufacturers making packaging or artistic paper. The dye is not intended for textiles requiring high washfastness. Packaging is in sealed polyethylene bags, but weight per bag is not specified. Buyers should confirm the dye content percentage, moisture level, and foreign matter content before bulk purchase, as these are critical for consistent coloration.

Before ordering, confirm the dye content percentage, moisture level, and particle size distribution with the supplier. Request a certificate of analysis for each batch, including heavy metal limits and pH. Do not accept bulk shipments without verifying these parameters, as variations directly affect dyeing performance and regulatory compliance.
Confirm the incoterms, packaging weight per bag, and lead time directly with the supplier. The listing does not specify these details. Ask whether the product is shipped in moisture-proof polyethylene bags with inner liners, and whether palletization or fumigation certificates are available. Lead times are not stated and may depend on order volume.
For quality control, inspect each shipment for moisture damage, clumping, or discoloration. Test solubility and pH of a small sample before dyeing. Request a traceable batch number and retain a sample for future reference. For leather applications, conduct a small-scale dyeing trial to confirm color match and fastness before full production runs.
