Acid Black 210 (Black N.spl / Nbh/nt) is an acid dye formulated for wool, nylon, silk, paper, leather, and ink applications. The product is supplied by Karsandas Mavji from Mumbai, Maharashtra, India. The dye is available in multiple packaging options to suit different industrial requirements. Its formulation relies on acid-based chemistry to achieve stable attachment to protein and polyamide fibres. The Colour Index designation 210 places it within the acid black series used extensively across textile and allied industries. Buyers should confirm the exact dye content percentage and salt specifications with the supplier before ordering.
Acid dyes of this class typically contain azo or anthraquinone chromophores solubilised by sulfonic acid groups. The N.spl, Nbh, and nt variants denote shade or strength modifications tailored to specific substrate requirements. Standard industrial grades typically show solubility in water at 60-80°C, with optimum exhaustion on wool at pH 4.0-6.0. The dye's affinity for amine-terminated nylon makes it suitable for hosiery and carpet applications. Light fastness typically ranges from 4-6 on the ISO Blue Scale, though buyers should request the specific rating for this variant. The powder or granular physical form allows for accurate metering in automated dosing systems.
Primary buyers include woollen textile mills, nylon carpet manufacturers, leather tanneries, and specialty paper producers. The ink industry uses acid blacks for fountain pen and stamping ink formulations. Karsandas Mavji positions this dye for industrial-scale procurement with flexible packaging. Importers should verify whether the supplier provides technical data sheets, safety data sheets, and batch consistency certificates. Payment terms, Incoterms, and minimum order quantities must be confirmed directly with the supplier, as these are not stated in the listing. The Mumbai location offers access to JNPT for sea freight export.

Before placing an order with Karsandas Mavji, verify the supplier's manufacturing licence and whether the Mumbai address corresponds to a production facility or trading office. Request a certificate of origin and a batch-wise certificate of analysis for at least three recent lots to assess consistency. Confirm that the acid dye meets the regulatory limits for restricted amines, heavy metals, and formaldehyde for your target market.

Lead time is not stated and must be negotiated directly, factoring in production schedules and port congestion.

Request details on HS code classification (typically 3204.12 for acid dyes), export licence status, and whether the supplier has experience with your country's import documentation requirements. Marine insurance and cargo consolidation services should also be discussed.
Upon arrival, conduct independent laboratory testing on the first shipment for dye content, moisture, and fastness properties against the supplier's certificate of analysis. Compare actual CIELAB values against the standard shade to detect batch-to-batch variation. Inspect packaging integrity for moisture ingress or physical damage. Retain samples from each batch for future reference in case of quality disputes. Documentation to collect includes commercial invoice, packing list, bill of lading, certificate of origin, SDS in your local language, and any eco-certifications claimed. Establish a pre-shipment inspection protocol if ordering regularly from this supplier.
