Import Bismark Brown — Buy in Bulk from Supplier in India

Bismark Brown is a synthetic azo dye supplied by S.K Chemicals from Vadodara, Gujarat, India, primarily formulated for kraft paper colouring and secondary textile applications. The dye exhibits strong affinity for cellulosic substrates, with a colour index designation that places it within the direct dye class for paper and packaging industries. S.K Chemicals offers this product with reported excellent solubility and stability characteristics, though specific lot analysis certificates should be requested for batch consistency data.

The dye chemistry relies on disazo and polyazo chromophores typical of brown direct shades, with molecular structures designed for moderate light fastness and good water solubility in alkaline papermaking conditions. Standard commercial grades range from 60% to 80% active dye content, with the balance comprising sodium chloride, sodium sulfate, or similar diluents and dispersing aids. For kraft paper applications, typical dosing falls between 0.1% to 0.5% on weight of fibre, depending on target shade depth and substrate porosity.

Primary buyers include kraft paper mills producing packaging grades, corrugated medium manufacturers, and specialty paper converters seeking consistent brown tones without the variability of natural lignin colouration. Secondary demand comes from cotton textile dyehouses requiring economical brown shades on unmercerised goods. S.K Chemicals lists flexible supply arrangements: buyers should confirm minimum order quantities, available packaging formats (typically 25 kg drums or bulk containers for dyes of this class), and whether the supplier provides technical support for shade matching on specific furnish compositions.

S.K Chemicals operates from 7, Tarangan Society, near Geb School, Baroda (Vadodara) 390015, Gujarat, India. The supplier's tier is marked as 'imported' with a trust tier of 'harbor', indicating a marketplace-listed entity without platform verification badges. The response rate stands at 0.00% with zero average response hours recorded, which signals that direct communication attempts through the platform have not generated measurable engagement. Buyers should note that this profile contains no stated years in operation, manufacturing capacity, employee count, or client references.

The source description attributes ISO and SGS compliance to the Bismark Brown product, though no certificate numbers, scopes, or validity dates are provided. S.K Chemicals positions itself as offering flexible trade terms including FOB and CIF shipping options, yet the listing lacks confirmed minimum order quantities, lead times, or documented quality control protocols beyond general claims. Prospective buyers should independently verify the supplier's manufacturing credentials, request site audit data, and confirm whether S.K Chemicals produces this dye in-house or operates as a trading intermediary.
