Certifications & compliance

COTFIX product approvals
and conformance evidence.

Check the named products, issuer references and verification dates below: 24 GOTS-listed inputs, 55 ECO PASSPORT entries and 34 Level 3 Gateway products checked separately. Coverage differs between schemes and catalogue grades. Supporting documents remain available on request.

Which scheme covers which COTFIX product, and when was each checked?

Nuchem Dyestuffs is one of the Indian reactive-dye manufacturers whose COTFIX range holds all three: GOTS-approved chemical inputs, OEKO-TEX ECO PASSPORT certification, and ZDHC MRSL v3.1 Level 3 conformance.

Which 24 COTFIX colourants are GOTS approved?

The 24 GOTS-approved COTFIX colourants match the approval appendix and the official database records checked on 29 September 2026. Each name links to a public verification record, and a differently named strength variant should not be assumed covered.

All 24 carry a 3 June 2024 approval date against MSDS dated 1 January 2024. A separate OEKO-TEX certificate covers 55 COTFIX products.

What does each approval document actually cover?

Certification language is dense by design. Four documents matter for a COTFIX buyer, and each answers a different question. GOTS approves chemical inputs, not finished textiles, so the 24 named colourants sit in the GOTS Approved Chemical Inputs database under Control Union. OEKO-TEX ECO PASSPORT certificate 21.0.64039 covers 55 products in category 2.6 Reactive dyes through Hohenstein Laboratories, recorded as valid until 30 June 2027. ZDHC MRSL v3.1 Level 3, verified for 34 active products at Control Union on 28 September 2026, is the tier brands ask for by name. The RSL screening report covers the REACH SVHC question for those 55 products. Read each document as chemical-product evidence for a named grade, then match the exact grade before use. None of the four certifies a buyer's finished garment, and each record applies to a named grade only.

Chemical-input approval is one part of GOTS processing

Nuchem's 24 named COTFIX colourants were listed in the official GOTS Approved Chemical Inputs database when checked on 29 September 2026. The records identify Control Union Certifications, GOTS v7.0 and a 3 June 2024 issue date. Match your exact grade and applicable conditions to the approval before use; chemical-input approval alone does not certify finished textiles.

ECO PASSPORT supports chemical-input selection

OEKO-TEX ECO PASSPORT certificate 21.0.64039 covers 55 named COTFIX products in category 2.6 Reactive dyes, with a recorded validity date of 30 June 2027. Product conditions still apply. This is chemical-product certification, not automatic STANDARD 100 certification of finished textiles.

ZDHC Level 3 is the tier brands ask for by name

ZDHC MRSL conformance runs in three levels. Level 1 covers document review and analytical evaluation; Level 2 adds an onsite assessment of management systems; and Level 3 requires chemical-hazard assessment capability plus evidence that the Level 1 and Level 2 principles are fulfilled. Nuchem's separate 28 September Gateway check verified 34 active products at Control Union Level 3; the 6 September report records its dated 25-product scope.

The RSL report covers the REACH SVHC screening question

The supporting screening report relates to the 55 named ECO PASSPORT products and the substance lists applicable on 27 July 2026. Request the relevant product documentation and safety data; screening is not a blanket guarantee about every catalogue grade, manufacturing process or finished textile.

How can a buyer verify each record independently?

Use the public issuer routes below for independent checks. Detailed product conditions and private supporting documents can be requested from Nuchem; Gateway access may require sign-in.

ZDHC Gateway

Search the ZDHC Gateway for Nuchem and organisation 01-78PRG39LX323-D. The 28 September 2026 check verified 34 active Level 3 product records, and the older 25-product ChemCheck report remains a dated snapshot. Keep the individual certificate dates separate.

Control Union

The inspected GOTS records name Control Union, and the saved approval reference is GOTS-C 810113-01-2024. Ask for the exact document and product scope required for your order.

Hohenstein

OEKO-TEX ECO PASSPORT certificate 21.0.64039, issued through Hohenstein Laboratories, is verifiable through the OEKO-TEX certificate check.

Document copies

Ask for the available approval, certificate and safety documents that apply to your selected grade. Private copies are not published on this website, so request the specific record for your order.

Questions buyers ask

The four that come up in almost every compliance conversation.

How can an export buyer verify a selected COTFIX dye?

For an export order, start with the exact COTFIX product name and strength variant. Nuchem's 24 named colourants appeared in the GOTS approved chemical-input directory when checked on 29 September 2026. OEKO-TEX ECO PASSPORT certificate 21.0.64039 lists 55 named products, with a recorded validity date of 30 June 2027. A separate check of the ZDHC Gateway found 34 active products at Control Union Level 3 on 28 September 2026. Match your chosen grade against each applicable record and its conditions; request its document from Nuchem. These are chemical-product records, not automatic certification of the buyer's finished textile or whole processing chain.

Are COTFIX chemical inputs GOTS approved?

Nuchem's 24 named COTFIX colourants were listed in the official GOTS Approved Chemical Inputs database when checked on 29 September 2026. The records identify Control Union Certifications, GOTS v7.0 and a 3 June 2024 issue date. Match your exact grade and applicable conditions to the approval before use; chemical-input approval alone does not certify finished textiles.

What ZDHC conformance level does Nuchem hold?

On 28 September 2026, Nuchem's 34 published ZDHC Gateway products were individually checked at MRSL v3.1, Control Union Level 3. Their active certificate records showed an end date of 18 February 2027. The separate ChemCheck Summary Report dated 6 September 2026 lists 25 COTFIX products; it is a dated report, not the latest portfolio count or a certificate.

Do the dyes have OEKO-TEX ECO PASSPORT certification?

OEKO-TEX ECO PASSPORT certificate 21.0.64039 covers 55 named COTFIX products in category 2.6 Reactive dyes, with a recorded validity date of 30 June 2027. Product conditions still apply. This is chemical-product certification, not automatic STANDARD 100 certification of finished textiles.

What does the OEKO-TEX RSL report confirm?

The supporting screening report relates to the 55 named ECO PASSPORT products and the substance lists applicable on 27 July 2026. Request the relevant product documentation and safety data; screening is not a blanket guarantee about every catalogue grade, manufacturing process or finished textile.

Need the certificates for a tender?

Tell us your selected grade and the documents your buyer requires, so Nuchem can check the applicable approval and conformance evidence. A tender pack usually needs the exact GOTS, ECO PASSPORT or ZDHC record for the named grade, plus the dated verification behind each claim. The 24 GOTS-approved colourants, the 55 ECO PASSPORT products under certificate 21.0.64039, and the 34 active Level 3 Gateway products are all checked separately, so the pack should match the grade on the order. Request certificate copies with the buyer's document list, the destination market and the required format, and Nuchem will confirm what can be released for the tender. Provide the buyer's deadline and the required delivery date so the team can prioritise the request. Documents are supplied for the selected grade only; a series name is not a whole-range approval.
