A comprehensive guide to EU REACH chemical testing items and processes for seat products, integrating the latest regulatory requirements and practical points:
I. REACH core test items
Based on the classification test of seat materials, focus on the following hazardous substances:
1. Heavy metal migration
- Metal parts (brackets, connectors): lead (≤90mg/kg), cadmium (≤75mg/kg), mercury (≤60mg/kg).
- Coating/electroplating layer: hexavalent chromium, nickel release detection.
2. Organic chemicals
- Plastic/rubber parts (armrests, seat surfaces):
- Phthalates (6 types including DEHP/DBP/BBP) ≤0.1%.
- Polycyclic aromatic hydrocarbons (PAHs) ≤1mg/kg (in contact with skin).
- Textile/leather fabrics:
- Azo dyes (decomposed into 24 carcinogenic aromatic amines) ≤30mg/kg.
- Short-chain chlorinated paraffin (SCCP) ≤ 0.15%.
3. Substances of Very High Concern (SVHC)
- The latest SVHC candidate list (211 items as of July 2025) needs to be tested, such as bisphenol A (BPA), perfluorinated compounds (PFAS), etc., with a concentration limit of ≤ 0.1%.
> Note: If the seat contains electronic components (such as electric adjustment devices), it is necessary to additionally comply with the RoHS Directive for electrical and electronic products.
2. Test process and timeliness
Phase 1: Preliminary preparation
- Material separation: Provide a list of materials for each component of the seat (metal/plastic/textile/filler) and supplier information.
- Sample requirements:
- Submit 3-5 complete sets of samples (including different colors/batches) for inspection;
- Special components (such as adhesives, coatings) need to be sampled separately.
Phase 2: Laboratory testing
Steps/key operations
Sample pretreatment: crushing/extraction by material classification (such as plastic dissolution test)
Chemical analysis: GC-MS (organic solvents), ICP-MS (heavy metals) and other equipment testing
SVHC screening: comparison with the latest candidate list (real-time update on ECHA official website)
Phase 3: Report generation
- After passing, obtain CMA/CNAS qualification report (no validity period, but material changes require retesting).
- Expedited service: report issued in 3 days (cost +30%).
III. Cost reference
- Basic test package:
- Non-metallic materials (textiles/plastics): 1,500 yuan/product
- Metallic materials: 1,000 yuan/product
- SVHC additions: about +500 yuan for each additional 20 substances.
IV. Key points of corporate compliance
1. Legal enforcement: Seats that fail REACH testing are prohibited from entering the EU market, and violators face product destruction and fines (up to 10 times the value of the goods).
2. Supply chain management:
- Require raw material suppliers to provide REACH compliance declarations;
- Re-inspection is required when batches are changed.
3. Label requirements: If the content of SVHC is greater than 0.1%, the substance name and safety instructions must be marked in the product manual.
> Practical advice: Choose a laboratory with EU accreditation (such as Dezewei) and regularly subscribe to ECHA's SVHC list update notification (about 10-15 items are added every six months).
> Note: The specific testing plan needs to be adjusted according to the seat design, for example:
> - Infant seats need to be tested for formaldehyde (≤30mg/kg) and migrating fluorescent brighteners;
> - If the pulleys of office chairs contain lubricants, polychlorinated biphenyls (PCBs) need to be tested.
