从India供应商批发进口Acid Red 34 Dyes — FOB条款

Sparrowings International supplies Acid Red 34 Dyes from Gujarat, India, under the alternate trade name Pontacyl Light Red 4BL. The material is identified by CAS number 6360-04-9 with molecular formula C16H12N4Na2O7S2 and EINECS registration 228-821-1, classifying it as a monoazo acid dye in sodium salt form. It is presented as a free-flowing powder suitable for industrial coloration of leather, paper, and plastics. The dye's chromophore structure delivers strong red hues through acid-dyeing mechanisms, with the sulphonate groups providing water solubility and substantivity toward cationic sites on protein and polyamide substrates. Gujarat's chemical manufacturing infrastructure supports consistent availability of this intermediate-to-specialty dye grade.

The powder appearance indicates a standardised milling and drying process, with typical particle size distribution favouring rapid dissolution and homogeneous dispersion in aqueous media. Standard commercial acid dyes of this class typically exhibit pH-dependent solubility profiles, with optimal dissolution between 50 and 80 degrees Celsius in soft water. Colour strength standardisation is usually expressed as a percentage of a defined physical standard, with typical values between 100 and 150 percent depending on manufacturer batch control. The EINECS listing confirms EU regulatory recognition, though buyers must verify current REACH registration status for import into European markets. Sparrowings International brands this material directly, suggesting either captive manufacturing or exclusive arrangement with a Gujarat-based production facility.

Target buyers include leather tanneries requiring level, penetrating red shades for garment and upholstery leathers; specialty paper mills producing decorative or security papers; and plastics compounders working with nylon or selected thermosets where acid dye dispersibility in the polymer matrix is achievable. The supplier's location in Ahmedabad, Gujarat (postal code 382330), places it within India's densest chemical manufacturing corridor, with potential access to Mundra or Kandla ports for export. Exact MOQ, pricing, and lead time are not disclosed in available data and must be negotiated directly. Response rate shows zero recorded history, so buyers should plan extended enquiry cycles and confirm sample policy before committing to commercial volumes.

Sparrowings International is located at D-101, Maruti Homes, opposite Shreenath Elegance, in Nana Chiloda, Ahmedabad, Gujarat, India (postal code 382330). The supplier carries a harbor trust tier designation with no recorded response rate or average response time, indicating that buyers should not rely on rapid turnaround for initial enquiries. The company brands its Acid Red 34 Dyes under its own name, which may reflect manufacturing ownership, toll production arrangementsek, or exclusive distribution rights within Gujarat's chemical sector.

No founding date, employee count, revenue figure, or client references appear in the available profile. The supplier's product focus spans leather, paper, and plastics dyestuffs rather than textile applications, suggesting technical specialisation or market positioning away from the more commoditised wool and nylon segments. Buyers should verify whether Sparrowings International operates as a manufacturer with in-house synthesis and standardisation capability, or as a trader with blending and repackaging operations, as this distinction affects batch consistency, technical support depth, and regulatory documentation availability.
