从India供应商批发进口Acid Red 362 — FOB条款

Acid Red 362 from Sparrowings International is an monoazochlorinated acid dye supplied as a free-flowing powder from Gujarat, India. Its CAS number is 61814-58-2 with molecular formula C16H12ClN4NaO5S and EINECS registration 612-464-7. The product carries the supplier's own Sparrowings branding and is positioned for textile dyestuff applications where acid dyes bond to protein fibres through ionic attraction. The dye's sodium salt form ensures ready solubility in aqueous dyebaths, a critical parameter for level dyeing on wool and silk substrates. Sparrowings International lists this material from their Ahmedabad location in the Naroda-GIDC textile belt, a region with deep historical concentration in synthetic dye manufacturing and export.

The powder form minimises dust exposure and allows precise weighing for laboratory shade matching or bulk production. Acid Red 362 belongs to the broader acid red family used for dyeing nylon, wool, silk and leather where brilliant red shades with moderate to good light fastness are required. Typical commercial grades of this dye class show exhaust rates of 80-95% under standard acid-dyeing conditions with sulphuric or formic acid as the pH regulator. The chloro substituent in the molecular structure contributes to improved wash fastness compared to unhalogenated analogues. Standard industry practice requires storage in sealed containers away from direct sunlight and moisture, as acid dyes are hygroscopic and prone to caking. The 61814-58-2 registry places this dye within the Colour Index system used globally for colourant identification and regulatory compliance.

Primary buyers include textile commission dyers, carpet manufacturers, hosiery producers and leather tanneries seeking reproducible scarlet to crimson shades. The dye is compatible with afterchrome and premetalised dye combinations for shade deepening on wool. Importers should verify the specific light fastness rating (typically ISO 105-B02 rating 4-5 for similar acid reds on wool) and wet fastness properties against their end-use requirements. Sparrowings International operates from a commercial address in Ahmedabad rather than a disclosed manufacturing site, so buyers should confirm whether this is traded stock or manufactured goods. No MOQ, lead time, packaging specification or Incoterm is stated in the listing data, so direct negotiation with the supplier is essential for commercial terms.

Sparrowings International is registered at D-101, Maruti Homes, Opp. Shreenath Elegance, Nana Chiloda, Ahmedabad 382330, Gujarat, India. This address is in a residential-commercial mixed zone of northern Ahmedabad rather than an industrial estate or manufacturing campus. The trust tier is marked as harbour, and the response rate is recorded at 0.00% with zero average response hours, indicating no historical buyer engagement data is available through the platform. The supplier profile does not disclose year of establishment, production capacity, number of employees, or turnover figures.

The listing presents Acid Red 362 under the Sparrowings brand name with basic chemical identifiers but omits manufacturing credentials, quality certifications, export licence details, and client references. The source description is limited to chemical registry numbers and physical form. Buyers should conduct independent verification of the supplier's manufacturing or trading relationships, as the available data does not distinguish between manufacturer, distributor, or broker status. No ISO, GOTS, ZDHC or REACH compliance documentation is mentioned.
