REACH Testing for Textile Fabrics: Restricted Substances, Test Methods, and Compliance Guide

REACH testing for textile fabrics verifies compliance with the European Union's Regulation (EC) No 1907/2006 on the Registration, Evaluation, Authorisation and Restriction of Chemicals, which imposes binding limits on hazardous substances in articles placed on the EU market. This technical guide covers the restricted chemicals most relevant to woven, knitted, coated, and printed fabrics, the corresponding laboratory test methods and sample requirements, and the practical compliance questions asked by manufacturers, brands, and importers.

Technical Overview

REACH is the European Union Regulation (EC) No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, in force since 1 June 2007 and administered by the European Chemicals Agency (ECHA). Under REACH, a finished fabric roll, a cut panel, or a garment is classified as an "article", which means the regulation controls the chemical substances contained in the material rather than the fabric as a product category. Compliance obligations for textile articles arise from two mechanisms: the restrictions listed in Annex XVII, which impose legally binding concentration limits on specific hazardous substances, and the Candidate List of Substances of Very High Concern (SVHC), which triggers communication and notification duties whenever a listed substance exceeds 0.1% by weight in the article.

For textile fabrics, the highest-risk chemical inputs are dyes, pigments, printing pastes, polymeric coatings, water-repellent finishes, washing auxiliaries, and metal hardware. REACH testing therefore focuses on restricted azo colourants, phthalate plasticizers, per- and polyfluoroalkyl substances (PFAS), alkylphenol ethoxylates, organotin compounds, extractable heavy metals, and nickel release from metallic trims. Because the Candidate List is updated approximately twice a year and now contains more than 240 entries, brands and importers typically require periodic screening to demonstrate continued conformity. Testing is carried out by accredited third-party laboratories operating under ISO/IEC 17025 quality systems, and the resulting test report supports EU market access, customs clearance, buyer verification, and responses to market surveillance authorities.

Testing Samples

REACH testing applies to the specific material composition of the fabric and each distinct component or colour. Different sample types carry different chemical risk profiles, so sampling plans should reflect the material inventory of the finished article.

Natural Fibre Fabrics

Cotton, linen, wool, and silk fabrics are primarily screened for restricted azo colourants, carcinogenic aromatic amines, nonylphenol ethoxylates carried over from scouring agents, and formaldehyde-based finishing residues. Dark and deep shades, as well as aftertreated reactive dyes, are prioritized because historically they present a higher rate of amine findings.

Synthetic and Blended Fabrics

Polyester, polyamide, acrylic, and elastane-containing fabrics are tested for disperse dye degradation products, organotin catalysts, PFAS-based durable water repellents, and heavy metals. Polyester blends with elastane additionally receive attention for diethyl phthalate contamination introduced by some elastane spinning processes.

Coated, Laminated, and Printed Fabrics

PVC and polyurethane coatings, plastisol screen prints, and laminated films represent the highest phthalate and organotin risk. Testing laboratories typically separate the coating or print layer from the base fabric and test each layer independently so that a non-compliant coating does not mask other findings.

Dyed and Finished Fabrics

Any dyed fabric in direct and prolonged contact with skin falls under the azo colourant restriction, while water-, oil-, or stain-repellent finishes are screened for PFOS, PFOA, and related PFAS substances. Soft-handle finishes and dye carriers are checked against the SVHC Candidate List.

Fabric-Attached Hardware and Trims

Metal buttons, zippers, rivets, buckles, and decorative chains attached to the fabric are assessed for nickel release, total lead, and cadmium, since these restrictions apply to the article as placed on the market, including its detachable and non-detachable components.

Testing Items

The following restrictions under REACH Annex XVII and the SVHC Candidate List are the core scope of a fabric compliance test programme. Limits are expressed per substance unless otherwise stated.

• Restricted azo colourants (Annex XVII, entry 43): 22 carcinogenic aromatic amines limited to 30 mg/kg each, with many buyer restricted substance lists extending the target list to 24 amines; an amendment effective from January 2025 extends the 30 mg/kg limit to aniline released from azo colourants in textile articles.
• Phthalates (entries 51 and 52, as amended by Regulation (EU) 2018/2005): DEHP, DBP, and BBP limited to 0.1% in sum, and DINP and DIDP limited to 0.1% in sum, in articles in prolonged skin or mucous membrane contact.
• PFOA (entry 68): 0.025 mg/kg for PFOA and its salts, and 1 mg/kg for the sum of PFOA-related compounds.
• PFOS (entry 75): 25 µg/kg in articles and 1 µg/m² in coated materials.
• Nonylphenol and nonylphenol ethoxylates (entry 46a): 0.01% (100 mg/kg) in textiles and textile articles, applicable since February 2021.
• Organotin compounds (entry 20): tributyltin, dibutyltin, dioctyltin, and related compounds restricted in articles with skin or mucous membrane contact, with typical limits of 0.1%.
• Chromium VI (entry 47): 3 mg/kg in leather articles or leather components of textile articles in skin contact, together with total chromium screening.
• Cadmium (entry 23): 0.01% in plastic components, paints, and surface coatings on or within the fabric construction.
• Lead (entry 63): 0.05% in articles, or accessible parts thereof, that may be placed in the mouth by children or subjected to prolonged skin contact.
• Nickel release (entry 27): 0.5 µg/cm²/week for metal parts in direct and prolonged skin contact, and 0.2 µg/cm²/week for piercing assemblies.
• Polycyclic aromatic hydrocarbons, PAHs (entry 50): 1 mg/kg per substance in plastic or rubber parts in skin contact, and 0.5 mg/kg in toys and childcare articles.
• CMR substances in clothing (entry 72): category 1A/1B carcinogenic, mutagenic, or reprotoxic substances restricted in clothing and related textile accessories per the appendix list.
• SVHC screening (Article 33): targeted verification of Candidate List substances against the 0.1% weight-by-weight communication threshold, with confirmation testing of any presumptive positive.

Testing Methods

Testing is performed using harmonized EN and ISO standards wherever they exist, supplemented by validated in-house chromatographic and spectrometric procedures. Each method involves destructive extraction or digestion, so sufficient sample mass must be allocated to every test item.

• Azo colourants: EN 14362-1 for extractable dyestuffs and EN 14362-3 for fibres where the colourant cannot be extracted; reductive cleavage in citrate buffer with sodium dithionite, followed by GC-MS or HPLC-DAD confirmation of the liberated amines.
• Phthalates: solvent extraction of the coating, print, or polymer matrix followed by gas chromatography–mass spectrometry (GC-MS) quantification against certified calibration standards.
• PFOS and PFOA: methanolic extraction followed by liquid chromatography–tandem mass spectrometry (LC-MS/MS) or GC-MS for volatile precursors, in line with the ISO 17881 series for perfluorinated compounds in textiles.
• Alkylphenol ethoxylates: ISO 18254, using LC-MS/MS to determine nonylphenol and its ethoxylated homologues.
• Formaldehyde: ISO 14184-1 for free formaldehyde by water extraction and ISO 14184-2 for released formaldehyde; although formaldehyde is not currently limited under Annex XVII for textiles, it is included in virtually all buyer restricted substance lists alongside REACH.
• Nickel release: EN 1811 wear-and-corrosion test in synthetic sweat with quantification by ICP-OES or AAS, preceded by EN 12472 abrasion for coated or plated components.
• Chromium VI in leather: EN ISO 17075-1 colorimetric determination or EN ISO 17075-2 chromatographic determination after phosphate buffer extraction.
• Total and extractable heavy metals: microwave acid digestion or artificial perspiration extraction followed by ICP-OES or ICP-MS measurement.
• Organotin compounds: acidified solvent extraction, derivatization, and GC-MS determination of individual tin species.
• SVHC screening: combined solvent extraction with tiered GC-MS, LC-MS/MS, and ICP-MS analysis against the current Candidate List, with confirmatory quantification of any substance exceeding 0.1%.

As practical guidance, laboratories generally require approximately 10 g of fabric per colour per test item, and a submission of 30 to 50 g per distinct material and colour is recommended to cover the full panel. Reports are issued within five to seven working days for routine Annex XVII items, and seven to ten working days for extended SVHC screening.

Applications

REACH fabric testing is applied across the textile value chain wherever products are placed on the EU market or supplied into EU-bound supply chains.

• Apparel and garment export compliance, supporting declarations of conformity and customs documentation for EU destinations.
• Home textiles such as bedding, curtains, upholstery, and towels, which are treated as skin-contact articles under the phthalate, azo, and flame-retardant-related restrictions.
• Children's clothing and childcare articles, where lower PAH and entry 72 limits apply and where fabric components are additionally assessed under EN 71-3 when used in toys.
• Technical textiles, workwear, and personal protective equipment, where chemical compliance is verified alongside performance requirements in EN PPE standards.
• Vendor qualification and incoming material control, enforcing brand restricted substance lists at the mill, dyehouse, and printing house level.
• E-commerce platform listings and marketplace compliance checks, which increasingly require a current REACH report as a listing condition.
• Recall mitigation and response to market surveillance enquiries, where an ISO/IEC 17025-accredited test report serves as documentary evidence of due diligence.

FAQ

Is REACH testing legally mandatory for fabrics exported to the EU?

The restrictions themselves are legally binding on manufacturers, importers, and distributors placing articles on the EU market, so the fabric must comply with Annex XVII whether or not it is tested. Testing by an accredited third-party laboratory is the standard means of demonstrating compliance, and most EU buyers and marketplaces contractually require a current test report as proof.

What is the difference between Annex XVII restrictions and the SVHC Candidate List?

Annex XVII restrictions are prohibitions or concentration limits that must never be exceeded, whereas the Candidate List creates a communication duty: if an SVHC exceeds 0.1% by weight in the fabric, the supplier must provide adequate information, on request, to allow safe use, and notification to ECHA is required if the total amount exceeds one tonne per year per producer or importer. Candidate List screening is preventive, while Annex XVII testing is enforcement-oriented.

How long is a REACH test report valid?

REACH does not assign an official validity period to test reports. In commercial practice, buyers typically accept reports issued within the previous twelve months, provided the material, formulation, and production process have not changed. Retesting is expected when the dye or chemical supplier changes, when the SVHC list is updated, or when a new colour or coating is introduced.

How should samples be prepared for submission?

Submit finished, production-representative fabric representing each distinct material, colour, coating, and print, at 30 to 50 g per combination. Metal trims should be included as complete components, and coated fabrics should be submitted in their finished state so the laboratory can separate and test the coating layer. Samples must be clean, unused, and packaged to prevent cross-contamination.

Which substances do fabrics most commonly fail?

Historical failure data from accredited third-party laboratories consistently points to restricted aromatic amines from certain azo dyes, phthalates in plastisol prints and PVC coatings, nonylphenol ethoxylates from washing and scouring agents, and PFAS in durable water-repellent finishes. Nickel release from low-cost metal trims is the most frequent non-textile-component finding.

Does REACH testing cover formaldehyde, pesticides, and odour?

Those parameters are not currently restricted under Annex XVII for general textiles and belong to buyer restricted substance lists and voluntary eco-label schemes rather than to REACH itself. However, most laboratories offer an integrated compliance panel that combines REACH items with these additional parameters using ISO 14184 and related methods, so a single sampling campaign can satisfy both legal and commercial requirements.
