从India供应商批发进口Acid Yellow 34 — FOB条款

Sparrowings International supplies Acid Yellow 34 (CAS 6359-90-6, EINECS 228-813-8) from Gujarat, India, under their own Sparrowings brand as a powdered acid dye. The molecular formula C16H12ClN4NaO4S identifies this as a monoazo chlorinated acid dye, a chemically distinct specification that enables buyers to verify structure and predict performance. The supplier explicitly designates usage across leather, paper, and textile dyestuffs, indicating a broader substrate compatibility than single-application alternatives. Sparrowings International is located in Ahmedabad, Gujarat, a region with established chemical manufacturing infrastructure.

The powder form is standard for acid dye commercial distribution, facilitating accurate weighing and dissolution in preparatory tanks. Acid dyes of this structural class typically exhibit good affinity for proteinaceous substrates (wool, silk) and aminated synthetics (nylon 6, nylon 6.6) through ionic bonding between sulfonate groups and cationic fibre sites. The sodium salt form (indicated by Na in the formula) ensures water solubility under acidic conditions. Standard commercial powder acid dyes typically contain 30-50% active dye content, with inert salts or dispersants as standardising agents, though Sparrowings International does not disclose their specific formulation details.

Leather tanneries represent a key buyer segment for this grade, utilising acid yellows for aniline and semi-aniline leather finishes where penetration and clarity are valued over heavy coverage. Paper dyestuffs applications include decorative and security paper colouring. Textile mills employ similar acid yellows for carpet yarns, hosiery, and woven goods on wool or polyamide. Sparrowings International does not list minimum order quantities, price bands, or lead times; these must be confirmed directly with the supplier. The response rate is recorded at 0.00%, so buyers should allow additional time for initial contact and consider multiple communication channels.

Sparrowings International is headquartered at D-101, Maruti Homes, opposite Shreenath Elegance, in Nana Chiloda, Ahmedabad, Gujarat 382330, India. The supplier holds a 'harbor' trust tier with no verification escalation to 'shipyard' or 'anchor' levels. Response metrics indicate 0.00% response rate with zero average response hours, suggesting limited platform engagement or resource allocation to incoming enquiries. No manufacturing facility details, production capacity, or quality management certifications (ISO 9001, ISO 14001, GOTS, Bluesign) are disclosed in the available profile.

The listing presents Sparrowings International as a branded acid dye supplier, though the profile does not distinguish between manufacturing, blending, or pure trading operations. Buyers should clarify whether Sparrowings formulates this dye in-house or sources from third-party manufacturers in Gujarat's chemical belt. The explicit provision of molecular formula and EINECS number suggests technical competence, but these are public registry numbers rather than proprietary verification. No transaction history, buyer references, or audit reports are accessible from the provided data.
