Import Acid Dyes For Leather — Buy in Bulk from Supplier in India

Libra Chemical Exports Co., based in Vadodara, Gujarat, India, lists a comprehensive range of acid dyes specifically positioned for leather applications. The catalogue encompasses fifty individual colour indices across the major acid dye families: acid black (3 variants), acid brown (9 variants), acid green (5 variants), acid red (12 variants), acid yellow (6 variants), acid blue (5 variants), acid violet (3 variants) and acid orange (4 variants). Acid dyes for leather are typically low-molecular-weight anionic colourants that penetrate the collagen structure of tanned hides, producing transparent, bright shades that preserve natural grain definition. The supplier's extensive colour palette suggests capability for matching both fashion and classic leather tones, from deep blacks and browns through vivid reds, oranges and violets.

The chemistry underlying these dyes varies by shade family. Acid blacks are often pre-metallised or disazo compounds offering superior light and migration fastness. Acid browns typically derive from monoazo and disazo structures with moderate sulphonation. Acid greens, reds, yellows and blues span azo, anthraquinone and triphenylmethane chromophores, each with specific affinity for chrome-tanned or vegetable-tanned leather. For leather application, the dye bath pH typically ranges from 3.5 to 5.0, controlled with formic or acetic acid, with exhaustion temperatures between 50°C and 70°C to prevent thermal damage to the protein matrix. Typical liquor ratios for drum dyeing are 2:1 to 5:1. The supplier does not specify wet fastness ratings, metal complex content, or solubility parameters, so these must be requested directly.

Buyers of leather acid dyes include tanneries producing footwear upper leather, garment nappa, upholstery hides, and leather goods. The aniline and semi-aniline finishing sectors demand dyes with high transparency and minimal surface deposition. Libra Chemical Exports Co.'s location in Vadodara places it within Gujarat's chemical manufacturing belt, with access to Mundra and Pipavav ports for export. No minimum order quantities, pricing, packaging specifications or lead times are provided in the source data. Buyers should contact the supplier directly to confirm availability of specific C.I. numbers, physical form, standardisation strength, and whether technical support for shade matching and dyeing recipes is offered.

Libra Chemical Exports Co. is located at 301 Felix, behind Iscon Heights on Gotri Road in Vadodara, 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 indicates no recent engagement via platform messaging, so buyers should use direct contact methods and anticipate possible delays in initial response. The supplier's profile is structured as a product list rather than a narrative description, which provides clarity on colour availability but offers limited insight into manufacturing capability, quality systems, or service infrastructure.

The source data does not state founding year, employee count, factory ownership, annual turnover, specific certifications, or named clients. The address suggests an office or trading location rather than necessarily a production site. Buyers should verify whether Libra Chemical Exports Co. manufactures in-house or sources from third-party dye producers, whether it holds ISO 9001 or ISO 14001 certification, and whether it can provide batch-specific certificates of analysis. Given the response rate data, consider requesting references from existing customers or arranging a site visit to Vadodara before committing to volume orders.
