It is supplied as a fine black powder and is primarily used in leather, paper, textile, and wood dyeing applications. The dye exhibits good water solubility and direct affinity for cellulose and protein fibers without requiring mordants.
This dye is typically formulated for applications requiring a deep, neutral black shade with moderate light and wash fastness. Its molecular structure includes fewer azo groups than Direct Black 19, which affects its color tone and stability. Standard commercial grades have a moisture content under 2.5% and are free from excessive soluble salts. The powder form allows for precise dosing in continuous dyeing systems.
Wood manufacturers use Direct Black 2 for staining high-value timber products, while paper mills apply it for high-opacity black printing paper. Textile buyers often select it for low-cost, bulk dyeing where extreme fastness is not critical. Packaging is typically in 25kg polypropylene bags with inner moisture barriers. Buyers should confirm compatibility with their dyeing method and request a batch-specific test report for consistency.

Before ordering, confirm that Direct Black 2 meets your end-use regulations, especially if used in wood products for export. Request a certificate of analysis for aromatic amines, heavy metals, and pH. Verify that the batch number on the label matches the test report. Do not accept shipments without a product specification sheet signed by the supplier.
Shipping is typically by sea in 20ft or 40ft containers, with lead times ranging from 18 to 35 days depending on port schedules. Incoterms are usually FOB Mumbai or Ahmedabad. Payment is commonly via 30% advance and 70% against copy of BL. Confirm that the supplier provides a bill of lading with correct HS code 3204.11. Buyers should ensure the packaging is marked as hazardous chemical under IMDG Code.
Conduct a dye test on a small sample of your substrate before bulk acceptance. Check for shade consistency, staining on adjacent materials, and fastness to light and water. Retain a reference sample from each shipment. If color variation exceeds ΔE 2.0 under CIE Lab, reject the batch and request a retest. Document all inspection results and maintain records for compliance audits.
