Who is Nuchem Dyestuffs,
and what does the company make?
Nuchem Dyestuffs (P) Ltd. manufactures high-quality COTFIX® reactive dyes for cotton, viscose and other cellulosic fibres at two plants in Gujarat, India.
Buyers can compare the range, review the published quality-control and water-treatment information, and request the documents for a selected grade.
Agents and distributors can discuss a COTFIX partnership with Nuchem; product suitability and chemical-input approval are separate checks.
The promoters of Nuchem Dyestuffs (P) Ltd. have been in the dye business since the 1960s. In 1996, they established their first manufacturing plant at Vatva, Ahmedabad, under the name Nuchem Industries; the business was later converted to Nuchem Dyestuffs (P) Ltd.
Founded in the 1960s by the late Sh. Kishori Lall Goyal, supplying reactive dyes and textile auxiliaries to the dyeing industry in Ludhiana.
First manufacturing plant established at Vatva, Ahmedabad, under the name Nuchem Industries; the business was later converted to Nuchem Dyestuffs (P) Ltd.

How does Nuchem treat wastewater
from reactive-dye manufacturing?
Nuchem publishes a wastewater-treatment approach combining reverse osmosis, Mechanical Vapour Recompression and an Agitated Thin Film Dryer. A two-stage reverse-osmosis plant recovers water ahead of evaporation, and the MVR and ATFD units then concentrate and dry the remaining process stream at the Sayakha and Vatva sites in Gujarat. The published material describes the equipment and the recovery sequence rather than a fixed performance guarantee. Capacity and current operating figures are confirmed for each site on request.
Nuchem also describes a green belt at the Sayakha site and publishes product-level approval evidence separately, because chemical-input approval does not certify a factory's water-treatment performance. Ask for the applicable site, current operating evidence and the document set covering a selected COTFIX grade, and request the conditions for each named product before use. Screening and approval scopes vary by product and strength variant.
How does Nuchem check and trace reactive-dye lots?
Nuchem describes a three-point quality check for manufactured dye lots before delivery and maintains production-lot records supporting traceability. The published approach names the checks rather than a lot-specific test report, so buyers can request the test information applicable to a selected grade. Each check applies to named products and conditions, never to the whole catalogue as one claim.
Nuchem lists four QC laboratories, at the Ahmedabad head office, the Ludhiana regional office, and the Sayakha and Vatva factories in Gujarat. QC means quality control, and the published summary does not state that every lot passes through all four laboratories.
The published product tables report shade-specific solubility at 30°C together with dry and wet rubbing, light and washing fastness values across 58 catalogue rows representing 57 distinct trade names. Compare the relevant row, then confirm the checks and lot information for the chosen grade.

Which approvals cover
Nuchem COTFIX reactive dyes?
Check the named products and dated evidence below. Scheme coverage differs between catalogue grades, and chemical-input approval is not finished-textile certification. Review the verification routes and product-specific limits.
The official GOTS database lists 24 named COTFIX colourants, individually checked on 29 September 2026. Records name Control Union, GOTS v7.0 and 3 June 2024. Saved approval reference: GOTS-C 810113-01-2024. Confirm exact grade and conditions before use.
Certificate 21.0.64039 (Hohenstein), category 2.6 Reactive dyes — 55 COTFIX products certified. Includes RSL screening against STANDARD 100, STeP MRSL, LEATHER STANDARD and REACH SVHC.
The 28 September 2026 Gateway check verified 34 active COTFIX products at ZDHC MRSL v3.1, Control Union Level 3; checked certificate records showed 18 February 2027. The separate ChemCheck Summary Report dated 6 September 2026 lists 25 COTFIX products as a dated snapshot. Organisation ID 01-78PRG39LX323-D; request documents for your selected grade.
The 55 named ECO PASSPORT products carry dated RSL/MRSL and REACH SVHC screening evidence; applicable lists, conditions and safety data remain product-specific.
Which textile clusters,
and which export markets, does Nuchem serve?
Nuchem serves domestic textile clusters including Surat, Tirupur, Panipat, Jetpur, Pali-Balotra, Jaipur, Delhi, Kolkata and Ludhiana, with reactive-dye supply for cotton and cellulosic processing. Buyers in each cluster can compare eight COTFIX series, review grade-level fastness tables and request documents for a selected grade. Grade-specific solubility and fastness values are published for 58 catalogue rows across the eight series.
Export markets served by Nuchem include Bangladesh, Turkey, Indonesia, Thailand, Vietnam, Sri Lanka, Egypt and Uzbekistan, together with Europe and North and South America. Marketing coverage does not establish an appointed distributor or an open exclusive territory; current territories, roles and support are confirmed individually with each partner. Nuchem handles domestic and export enquiries and can discuss a distribution or agency partnership with Nuchem, and no market is reserved by an enquiry, because product suitability and approval coverage are checked for each selected COTFIX grade.
How do I request a COTFIX
quote, sample or shade match?
Request a quote, a sample, a shade match, a shade card or a partnership conversation by including your grade, process and document requirements in the enquiry form. Nuchem handles domestic and export enquiries for COTFIX® reactive dyes, with the head office at Ahmedabad, manufacturing at Sayakha in Bharuch and at Vatva in Ahmedabad, and a regional office in Ludhiana. Buyers can state the target shade, the substrate, the dyeing or printing process and any buyer scheme the order must satisfy. Written requests sent through the form reach the sales team directly, and sales contacts, current territories and sample availability are confirmed individually. Quotes, samples and shade matches are prepared for the named grade and process. For an export order, note the destination market and the documentation the buyer requires. Product suitability, chemical-input approval and finished-textile certification remain separate checks for every order.
