从India供应商批发进口Acid Green 1 — FOB条款

Acid Green 1 (CAS 19381-50-1, EINECS 243-010-2) is an iron-complexed azo acid dye supplied by Sparrowings International from Ahmedabad, Gujarat. Its alternative name, Naphthol Green B, reflects its basis in naphthol chemistry with a molecular formula of C30H15FeN3Na3O15S3. The product is presented as a powder, the conventional form for industrial acid dyes, and is positioned for leather and textile dyestuff applications.

The iron complex in Acid Green 1 contributes to its colour strength and solubility characteristics, distinguishing it from simpler azo acid dyes. Naphthol Green B is typically used where moderate to good light fastness is required on protein and polyamide substrates. Standard commercial material of this type generally carries a dye content in the range of 75-85% by typical industry specification, though buyers must request batch-specific data. The powder form allows for precise weighing and dissolution in aqueous dyebaths with controlled pH and temperature.

Leather tanneries and textile commission dyers represent the core buyer segments for this material, with applications spanning garment leather, shoe upper leather, and wool or nylon textiles. Sparrowings International offers the product under its own brand name. Prospective importers should confirm packaging specifications, stock availability, and export documentation practices directly with the supplier, as these operational details are not included in the listing.

Sparrowings International is located at D-101, Maruti Homes, opposite Shreenath Elegance, Nana Chiloda, Ahmedabad, Gujarat 382330, India. The company holds a Harbor trust tier classification on the platform, with a response rate of 0.00 and zero recorded average response hours, suggesting limited or no transaction history through the platform. No information is provided about years established, production capacity, factory certification, or export experience.

The listing identifies Sparrowings International as the brand name for Acid Green 1, with the product positioned for leather and textile dyestuff use. The supplier address indicates a commercial rather than industrial zone, which may imply trading or distribution rather than primary manufacturing. Buyers should investigate whether the company manufactures the dye in-house or sources it from third-party producers, and whether it maintains quality control laboratories or relies on manufacturer certificates of analysis.
