Before ordering Direct Blue 6, verify the batch-specific color strength, moisture content, and heavy metal limits with a certificate of analysis. Confirm that the dye meets your application's regulatory requirements, especially if used in paper for food packaging or printing inks. Request a small sample batch for dyeing trials to assess shade consistency and fastness against light and rubbing.
Confirm the Incoterms with the supplier - commonly FOB Mumbai or CIF destination - and clarify whether the supplier arranges export documentation. Lead times typically range from 14 to 20 days after order confirmation, depending on production scheduling. Payment terms are usually 30% advance and 70% against copy of BL. Ensure the supplier provides a commercial invoice, packing list, and bill of lading with accurate HS codes.
For quality assurance, inspect each shipment for moisture damage, clumping, or discoloration upon arrival. Request a sample from each batch for spectrophotometric analysis to verify color match against the approved standard. Retain a reference sample for future comparisons. Ensure all documentation includes the CAS number, batch number, and manufacturer details for traceability and customs clearance.
