从India供应商批量进口Acid Dyes

Karma International supplies acid dyes from its base in Ankleshwar, Gujarat, India. These dyes are water-soluble anionic colourants applied to protein fibres such as wool, silk and nylon, as well as to leather. The supplier's range covers the standard colour index families including acid black, acid brown, acid green, acid red, acid yellow, acid blue, acid violet and acid orange. Typical commercial forms include powder and granular presentations, with standard purities ranging from 80 percent to 98 percent depending on the specific dye chemistry. The dyes function through ionic bonding to cationic sites in the substrate, which demands controlled pH conditions, generally in the acidic range of 2.5 to 5.5, for optimal exhaustion and levelness.

The chemical foundation of acid dyes lies in azo, anthraquinone, triphenylmethane or xanthene chromophores, often combined with sulphonate or carboxylate solubilising groups. Karma International's source description notes ISO certification and a commitment to colourfastness and durability, though buyers should request the specific ISO standards held, such as ISO 9001:2015 for quality management. Typical light fastness ratings for acid dyes on wool range from 4 to 6 on the ISO 105-B02 scale, while wash fastness typically falls between 3 and 5 on ISO 105-C06. The supplier emphasises regular product review and new molecule introduction, suggesting a portfolio that evolves with market demand rather than a static catalogue.

Primary applications span textile dyeing, leather finishing, paper coloration and ink manufacture. The buyer base includes garment exporters, tanneries, carpet manufacturers and specialty chemical distributors. Karma International's distribution network covers domestic Indian markets and export destinations. Buyers should confirm minimum order quantities, available Incoterms, and lead times directly with the supplier, as these are not stated in the source data. The response rate is currently logged at 0.00 percent, so buyers may need persistence or alternative contact channels to secure quotations and technical data sheets.

Karma International operates from A1-304 Akshar Redidency, near Jaldhara Chokdi in the GIDC area of Ankleshwar, Gujarat, India. The company holds a harbor trust tier on the platform, with a response rate of 0.00 percent and no recorded average response hours. This signals limited or no recent engagement through the platform's messaging system, so buyers should expect to initiate contact through direct channels and may need follow-up persistence. The supplier describes itself as an ISO certified manufacturer, supplier, trader and exporter of acid dyes, serving both domestic Indian clients and international markets through a network of marketing associates.

The source profile does not state founding year, employee count, annual turnover, factory floor area, or specific client names. Karma International emphasises attendance at trade shows and continuous market review to update its product offering with new molecules. Buyers should verify the exact ISO certificates held, request a current product list with CAS numbers or Colour Index numbers, and confirm whether technical support for dyeing recipes and troubleshooting is available. The absence of response data means due diligence on supplier reliability should include reference checks or sample orders before committing to bulk volumes.
