从India供应商批发进口Acid Green 25 — FOB条款

Sparrowings International supplies Acid Green 25 from Gujarat, India, a state with deep roots in dyestuff manufacturing and export. The product carries CAS number 4403-90-1 and EINECS number 224-546-6, with the molecular formula C28H20N2Na2O8S2 confirming its identity as a sulfonated acid dye suitable for protein and polyamide substrates. The supplier markets this material under the brand name Sparrowings, offered in powder form for leather, paper, textile and polyamide applications. Unlike commodity traders, Sparrowings International presents specific chemical identifiers that allow buyers to cross-reference technical literature and regulatory databases. Buyers should note that purity, colour strength and fastness grades are not quantified in the source data and require direct supplier confirmation.

The molecular architecture of C28H20N2Na2O8S2 incorporates two sodium sulfonate groups that confer water solubility and substantivity towards cationic sites on wool, silk and nylon fibres. In standard industrial practice, Acid Green 25 of this structural type exhibits moderate to good affinity for polyamide under weakly acidic conditions, with typical exhaustion temperatures between 80°C and 95°C depending on substrate and depth. The Gujarat origin is significant; the region hosts integrated dyestuff clusters with access to intermediate chemicals and established logistics infrastructure. Commercial grades typically contain 80-90 percent active dye content with balancing agents such as sodium chloride or dextrin, though Sparrowings International does not state its specific formulation. The powder form requires controlled storage conditions to prevent agglomeration and moisture pickup.

Target buyers for this Sparrowings International offering include leather tanneries requiring vibrant green shades for garment and upholstery leather, paper mills producing decorative or security papers, textile commission dyers serving fashion and home textile markets, and polyamide fibre processors. The supplier operates from Ahmedabad, Gujarat, with a harbor trust tier and zero percent platform response rate, signalling the need for proactive outreach. No MOQ, pricing, lead time or packaging specifications are disclosed. Buyers should request a comprehensive technical data sheet, samples for substrate-specific trials, and clarity on whether Sparrowings International manufactures this dye or trades under arrangement with a domestic producer. Verification of batch-to-batch consistency and regulatory compliance documentation is essential before contract commitment.

Sparrowings International is located at D-101, Maruti Homes, opposite Shreenath Elegance, Nana Chiloda, Ahmedabad 382330, Gujarat, India. The supplier holds a harbor trust tier on the platform with a zero percent response rate and no logged average response hours. The Ahmedabad location places the company within Gujarat's chemical manufacturing belt, though the residential-sounding address suggests a trading office rather than production facility. No factory address, warehouse details or manufacturing capacity is disclosed.

The supplier profile does not indicate founding year, ownership structure, employee count, annual turnover, export markets, or client references. No certifications such as ISO 9001, ISO 14001, Oeko-Tex, GOTS, or ZDHC conformance are mentioned. The brand name Sparrowings appears to be a proprietary or trading designation rather than an internationally recognised dyestuff brand. Buyers should conduct due diligence including verification of GST registration, IEC code and any manufacturing or wholesale licences, and should request references from existing customers before extending advance payments or entering contractual commitments.
