Azo-Free Dyes and REACH: A Buyer's Guide to Hand Block Printed Textiles

Oct 10

6 min read

Colour sells hand block printed bedding, cushions and bags, and it raises most chemical compliance questions. Some azo dyes can break down into aromatic amines that are restricted in Europe. Finishes can add formaldehyde. Water-repellent treatments can bring in PFAS.

This guide explains the main EU and UK rules, India's own controls on hazardous dyes, where natural and synthetic dyes fit in Sanganeri and Bagru printing, and how to test before you ship.

EU REACH Annex XVII, entry 43: azo colourants

REACH is the EU's chemicals law. Its Annex XVII lists restricted substances. Entry 43 says azo dyes that may release any of the aromatic amines listed in Appendix 8 must not be used in textile and leather articles that may come into direct and prolonged contact with human skin or the mouth.

Products named include clothing, bedding, towels, handbags, purses, chair covers, and yarn and fabrics intended for final consumers.
The limit is 30 mg/kg (0.003% by weight) of each listed amine in the article or in its dyed parts.
Market ban: articles that do not meet the limit must not be placed on the EU market.
Dye powders: the azo dyes listed in Appendix 9 may not be sold or used above 0.1% by weight in substances or mixtures meant for colouring textiles and leather.

For a block print buyer, this means bedsheets, pillow covers and bags are in scope. Cushion covers, tablecloths and curtains may also be in scope if they come into prolonged skin contact.

Other REACH entries that affect home textiles

Entry 72: CMR substances in textiles. Commission Regulation (EU) 2018/1513 added entry 72. Since 1 November 2020, it has restricted listed carcinogenic, mutagenic or reprotoxic (CMR) substances in consumer clothing, accessories, footwear, and other textiles that touch the skin in a similar way to clothing. The regulation gives bed linen, blankets and upholstery as examples. Key points:

Formaldehyde has a limit of 75 mg/kg. A temporary 300 mg/kg limit for jackets, coats and upholstery ended on 1 November 2023.
Exemptions include second-hand items, wall-to-wall carpets, indoor textile floor coverings, rugs and runners, and non-textile fasteners and decorations.

Entry 77: formaldehyde emissions from articles. Regulation (EU) 2023/1464 sets formaldehyde emission limits for articles placed on the market after 6 August 2026. The limits are 0.062 mg/m³ for furniture and wood-based articles and 0.080 mg/m³ for other articles. Articles already covered by entry 72 are exempt, so the rule matters more for wooden homeware than for skin-contact textiles.

Entry 79: PFHxA (a PFAS group). Regulation (EU) 2024/2462 limits PFHxA to 25 ppb and PFHxA-related substances to 1,000 ppb. It applies to consumer clothing and accessories from 10 October 2026. Other consumer textiles, including curtains and upholstery, follow from 10 October 2027. If you ask for a stain- or water-repellent treatment, ask what chemistry is used.

UK REACH

Great Britain has its own version of REACH. The UK text of Annex XVII on legislation.gov.uk includes entry 43, with the same 30 mg/kg azo limit and the same product list, including bedding. legislation.gov.uk notes that this text reflects EU law as of 31 December 2020, with UK amendments applied since then. EU restrictions adopted later, such as the PFHxA restriction, are not part of that text. The Health and Safety Executive publishes the current list of UK REACH restrictions. Check it before you assume an EU rule also applies in Great Britain.

India's own controls on hazardous dyes

India controls hazardous dyes under the Environment (Protection) Act, 1986. The Directorate General of Foreign Trade's import policy general notes let textiles into India only if they contain none of the hazardous dyes "whose handling, production, carriage or use is prohibited" under Section 6(2)(d) of that Act. Imports need a pre-shipment test certificate from an accredited laboratory, or customs testing on arrival. Countries that already ban azo dyes in textiles are exempt from this procedure.

This reflects India's firm stance on hazardous dyes: the government treats them as banned substances. For your own compliance records, still test each order to your market's rules, since REACH sets a specific 30 mg/kg limit.

Natural and synthetic dyes in Sanganeri and Bagru printing

Both crafts are registered Geographical Indications. Bagru Hand Block Print appears in the Indian GI registry. India's tourism ministry notes that Sanganeri prints received GI status in 2010.

Sanganeri: the Development Commissioner (Handicrafts) craft profile lists both natural and synthetic dyes as raw materials.
Bagru: the Bagru craft profile describes black from iron filings, jaggery and gum, red from madder and alum, and harda as a pre-treatment. It also notes that some workshops now also use modern dyes to serve larger orders.

"Natural dye" and "azo-free" are not the same claim. REACH restricts only the azo dyes that can release listed amines, not synthetic dyes in general, and a natural-dye claim still needs evidence. Agree in writing which dye system is used for your order, and test the result. Our Sanganeri block print buyer guide covers the craft in more detail.

How to test: methods, timing and records

REACH Appendix 10 sets the test methods for entry 43. Regulation (EU) 2020/2096 updated them to EN ISO 14362-1:2017 and EN ISO 14362-3:2017 for textiles. ISO 14362-1 detects certain azo colourants in dyed, printed and coated textiles.

Check	Method or rule	Limit
Azo amines	EN ISO 14362-1 and -3	30 mg/kg per amine
Formaldehyde (skin contact)	REACH entry 72	75 mg/kg
PFHxA (if repellent finish)	REACH entry 79	25 ppb
Listed CMRs	REACH entry 72	Per Appendix 12

Practical steps:

Test the approved sample and a sample from bulk production, covering each colourway.
Use an accredited laboratory and ask for the report to name the test method and the regulation.
Keep test reports with your import records so you can answer a regulator or retailer.
Re-test when the dye house, dye lot or recipe changes.

Our sample-to-bulk ordering guide shows where testing fits in the order timeline.

Voluntary labels: OEKO-TEX and GOTS

OEKO-TEX STANDARD 100 tests every component of an article against a list of over 1,000 harmful substances. Bed linen falls in product class 2 (direct skin contact) and curtains in class 4. Certificates are issued for one year and can be checked online.
GOTS (Global Organic Textile Standard) requires at least 70% certified organic fibre, or 95% for the "organic" grade. It also sets chemical input restrictions for dyes and auxiliaries.

Neither label is legally required.

This article is general guidance, not legal advice. Confirm the current rules for your products with your customs broker or the regulator in your market.

FAQ

Does REACH ban all azo dyes?

No. Entry 43 restricts azo dyes that can release the aromatic amines listed in Appendix 8 above 30 mg/kg, and separately limits the Appendix 9 azo dyes in dye mixtures. Other dyes are outside entry 43, though other REACH entries may still apply.

Are bedsheets and cushion covers covered?

Bedding is named in entry 43, and entry 72 gives bed linen and upholstery as examples of textiles in skin contact. Treat both as in scope.

Is a natural dye certificate enough?

No. You still need lab test results to the relevant REACH limits, because a natural-dye claim does not show the amine or formaldehyde levels in the finished product.

Do UK and EU rules match?

For azo dyes, yes: GB REACH keeps entry 43. Newer EU restrictions, such as the PFHxA restriction, do not automatically apply in Great Britain.
