The product is marketed as a 100 % strength dye and appears as a blackish‑blue powder. It is classified as a direct dye and is produced for use in leather, paper and textile applications.

In the dye industry the colourant is typically offered with a purity of at least 90 % and a moisture content below 0.5 % to ensure consistent uptake.

The supplier also lists a broader portfolio of related direct blue colours, indicating capability to source adjacent shades if required.

The powder is normally packed in 25 kg kraft bags, with the option of ion‑drum or carton packing according to the buyer’s request. Importers should confirm the minimum order quantity, preferred incoterm and any specific packaging requirements before placing an order. Lead times are described as prompt, but exact delivery schedules must be agreed with the supplier. Payment terms and inspection arrangements should be clarified in the trade contract to align with the buyer’s risk management policy.
