REACH testing for recycled materials is a critical compliance step for manufacturers and importers placing recycled plastics, rubber, metals, and textiles on the EU market, because waste-stream contamination can introduce restricted substances absent from virgin feedstocks. This guide explains the regulatory basis, typical sample types, key testing items, analytical methods, and practical considerations for verifying that recycled materials meet the requirements of Regulation (EC) No 1907/2006. Understanding SVHC thresholds, Annex XVII restrictions, and appropriate sampling strategies helps recyclers and downstream users avoid costly non-compliance and supply chain disruptions.
Technical Overview
REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is the European Union regulation (EC) No 1907/2006 governing the production and use of chemical substances. For recycled materials—commonly referred to as recyclate or regrind—the regulation presents distinct compliance challenges compared with virgin feedstocks. Because recycled inputs originate from post-consumer or post-industrial waste of varying and often unknown composition, they carry an elevated risk of containing Substances of Very High Concern (SVHC) from the REACH Candidate List or substances restricted under Annex XVII.
Under Article 33 of REACH, any supplier of an article containing an SVHC above 0.1% weight-by-weight (w/w) must provide adequate information to allow safe use of the article. Annex XVII, meanwhile, imposes specific concentration limits or use prohibitions—for example, on certain phthalates, cadmium, lead, polycyclic aromatic hydrocarbons (PAHs), and short-chain chlorinated paraffins (SCCPs). Recycled plastics are particularly susceptible to legacy additives such as brominated flame retardants from waste electrical and electronic equipment (WEEE) streams, plasticizers from older flexible PVC, and heavy-metal pigments from historic colorant formulations.
Chemical testing performed by accredited third-party laboratories is therefore the standard means of demonstrating that recycled materials conform to REACH obligations before they enter products such as packaging, consumer goods, electronics, toys, and automotive components.
Testing Samples
Post-Consumer Recycled Plastics (PCR)
Flakes, pellets, or regrind derived from end-of-life products such as beverage bottles (rPET), containers (rHDPE, rPP), and mixed rigid packaging. Post-consumer streams carry the highest contamination uncertainty and should be tested for the full range of legacy additives and restricted substances.
Post-Industrial Recycled Plastics (PIR)
Reprocessed sprues, runners, offcuts, and production scrap with a documented origin. Although the material history is generally better characterized, verification testing is still recommended to confirm freedom from SVHCs and Annex XVII substances, particularly when the scrap originates from multiple sources.
Recycled Rubber and Elastomers
Crumb rubber, reclaimed rubber, and devulcanized elastomers derived from tires or industrial goods. These materials require focused attention on PAHs, which are restricted in articles with prolonged skin or oral contact under Annex XVII entries 50 and 72.
Recycled Metals and Alloys
Reclaimed aluminum, copper, zinc, and steel streams intended for articles with consumer contact. Testing targets restricted elements such as lead, cadmium, and hexavalent chromium, as well as nickel release where skin-contact metal components are involved.
Recycled Textiles and Fibers
Regenerated cellulose, recycled polyester (rPET fiber), and recovered natural fibers used in apparel, home textiles, and applications. Screening covers azo colorants that may release restricted aromatic amines, along with phthalates and perfluorinated compounds.
Testing Items
The scope of REACH testing for recycled materials typically combines a broad SVHC screen with targeted verification of Annex XVII restrictions relevant to the polymer or material type:
- SVHC Candidate List screening — full-scan or targeted analysis against the current Candidate List (updated approximately twice per year, now exceeding 240 substances), reported against the 0.1% w/w threshold.
- Phthalates — DEHP, DBP, BBP, DIBP, DINP, DIDP, DNOP, and DNHP, restricted in plasticized materials and consumer articles.
- Heavy metals — lead, cadmium, mercury, and hexavalent chromium, with material-specific limits under Annex XVII entries 23, 63, and 75.
- Polycyclic aromatic hydrocarbons (PAHs) — the eight restricted PAHs, each limited to 1 mg/kg (0.0001% by weight) in rubber or plastic articles with skin or oral contact.
- Brominated flame retardants — legacy PBDEs (penta-, octa-, and deca-BDE) and HBCDD frequently encountered in recycled ABS, PS, and PC/ABS from electronic waste.
- Short-chain chlorinated paraffins (SCCPs) — restricted to 1% by weight, a common contaminant in recycled PVC and rubber from older flame-retarded and plasticized goods.
- Organotin compounds — including tributyltin (TBT), dibutyltin (DBT), and dioctyltin (DOT) compounds used as stabilizers and biocides.
- Nonylphenol and nonylphenol ethoxylates — restricted in textiles and leather processing, relevant to recycled fiber streams.
- Azo colorants — those capable of releasing one of the restricted carcinogenic aromatic amines, applicable to dyed recycled textiles and plastics.
- Nickel release — for recycled metal components intended for prolonged skin contact, such as jewelry findings and fasteners.
Testing Methods
Analytical procedures follow internationally recognized standards and EN methods adapted to polymer and material matrices. Sample preparation generally begins with cryogenic milling to produce a homogeneous particle size below 0.5 mm, ensuring representative extraction of heterogeneous recyclate.
- Inductively coupled plasma optical emission spectrometry (ICP-OES) or ICP mass spectrometry (ICP-MS) — quantitative determination of lead, cadmium, mercury, and total chromium following acid digestion (aligned with methods such as EN IEC 62321-5 series practice for metals in polymeric matrices).
- Gas chromatography–mass spectrometry (GC-MS) — determination of phthalates, PAHs, SCCPs, and brominated flame retardants after solvent extraction (for example, with toluene, acetone, or hexane), with detection limits well below regulatory thresholds.
- UV-visible spectrophotometry — colorimetric determination of hexavalent chromium in accordance with methods comparable to EN IEC 62321-7-1 and EN ISO 17075 for leather.
- High-performance liquid chromatography (HPLC) or LC-MS — analysis of azo dye cleavage amines and selected SVHCs not amenable to GC analysis.
- X-ray fluorescence (XRF) spectrometry — rapid screening of elemental composition to triage lots and flag elevated bromine, chlorine, or metal content for confirmatory analysis.
- Pyrolysis-GC-MS — qualitative identification of polymer type and associated legacy additives in unknown or mixed recycled streams.
Because recycled lots can vary between batches, laboratories typically recommend composite sampling across a production run, with confirmatory testing of any suspect fraction. Reports should state the method, reporting limit, and a clear pass/fail conclusion against both the 0.1% w/w SVHC reporting threshold and applicable Annex XVII limits.
Applications
REACH compliance testing of recycled materials supports product safety and market access across numerous sectors:
- Packaging — recycled PET and polyolefin food-contact and general packaging, often evaluated alongside EU food contact regulations for a complete compliance dossier.
- Consumer electronics and electrical equipment — recycled engineering plastics (rABS, rPC, rHIPS) in housings and structural parts, frequently tested in combination with RoHS Directive requirements.
- Toys and childcare articles — recycled plastics subject to stricter migration and restricted-substance limits under REACH and EN 71 safety standards.
- Automotive — recyclate used in interior trim, underbody components, and battery housings, supporting both REACH conformity and end-of-life vehicle recycling targets.
- Textiles and footwear — recycled fibers, rubber outsoles, and TPR components requiring PAH, phthalate, and azo dye verification.
- Construction products — recycled PVC profiles, insulation materials, and rubber flooring needing confirmation of flame retardant and heavy-metal compliance.
FAQ
Is REACH testing mandatory for recycled materials? While REACH does not always prescribe a specific test for every article, producers and importers bear legal responsibility for ensuring their articles do not contain restricted substances above limits and for communicating SVHC content above 0.1% w/w. Testing by accredited third-party laboratories is the accepted method of demonstrating this due diligence, and EU customers increasingly demand it as a contractual condition.
Why are recycled materials higher risk than virgin materials? Recyclate aggregates products manufactured over decades under different regulatory regimes, so legacy additives that have since been restricted—deca-BDE, certain phthalates, cadmium pigments—can re-enter the supply chain. Heterogeneous sorting and cross-contamination between waste streams further increase the probability of non-compliant concentrations.
How much sample is required, and how long does testing take? Typical laboratory requirements are 20–50 g of homogeneous milled material per program, or roughly 50–100 g of flakes or pellets to allow milling on site. A combined SVHC screen and Annex XVII package generally takes 7–10 working days; urgent services can shorten turnaround where available.
What is the difference between SVHC screening and Annex XVII testing? SVHC screening addresses Candidate List substances with an information obligation at 0.1% w/w, whereas Annex XVII testing verifies legally binding restrictions whose limits vary by substance and application (for example, 0.1% for the four regulated phthalates or 1 mg/kg per PAH). A comprehensive program covers both, tailored to the material and end use.
How often should recycled lots be retested? Best practice is to test each new source stream and retest when the waste-stream composition, supplier, or recycling process changes, with periodic verification (for example, quarterly or semi-annually) for ongoing high-volume supplies to control batch-to-batch variability.
Does a passing test result remain valid? A report reflects only the submitted sample. Because the SVHC Candidate List is updated approximately every six months and Annex XVII limits evolve, compliance documentation should be reviewed against the current lists at least annually, and certificates are typically refreshed every 12 months or upon regulatory change.
