Office Chair REACH Standard

Office chairs must comply with the EU's REACH Regulation (EC) No 1907/2006, which primarily requires that the content of Substances of Very High Concern (SVHCs) in materials does not exceed 0.1% (w/w), and notification to the European Chemicals Agency (ECHA) is required if this limit is exceeded.

I. Core Scope of Control under the REACH Regulation

The REACH Regulation covers the entire material chain for office chairs, including gas springs, metal components of the chair body, seals, coatings, plastic parts, and textile materials. SVHCs that may be present in these components include:

• Heavy Metals: Metal components (such as gas springs and brackets) may contain lead and cadmium. Prolonged exposure can allow these metals to enter the body through the skin or respiratory tract, potentially damaging the nervous system or kidneys.
• Phthalates: Plastic components (such as armrests and chair backs) may contain plasticizers like DEHP and DBP, which have endocrine-disrupting properties and may affect reproductive system development.
• Azo Dyes and Formaldehyde: Textile materials (such as chair surface fabrics) may contain azo dyes (some of which can decompose into carcinogenic aromatic amines) or formaldehyde. Prolonged exposure can trigger skin allergies or respiratory diseases.
• Solvents and Flame Retardants: Coatings or adhesives may contain volatile organic solvents (such as toluene) or brominated flame retardants (such as polybrominated diphenyl ethers), which have environmental persistence and bioaccumulation potential.

II. Testing Techniques and Compliance Requirements

Companies need to test materials using chemical analysis techniques (such as GC-MS and ICP-MS) to ensure that SVHC content is below 0.1% (w/w). For example:

• GC-MS (Gas Chromatography-Mass Spectrometry): Used to detect phthalates in plastics or formaldehyde in textile materials by separating and identifying compound molecular structures to confirm content.
• ICP-MS (Inductively Coupled Plasma Mass Spectrometry): Used to analyze heavy metals like lead and cadmium in metal components by ionizing metals with high-temperature plasma and then detecting concentration.
  If testing reveals that a material contains SVHCs and the concentration exceeds the limit, companies must notify the ECHA within six months of placing the product on the market, providing information such as the substance name, concentration, intended use, and safety assessment.

III. Corporate Compliance Responsibilities and Risks

Office chairs that do not meet REACH requirements may face prohibition from the EU market, product recalls, or substantial fines. Companies need to establish a supply chain traceability system, requiring suppliers to provide material compliance declarations or test reports, and regularly conduct spot checks on products. For example, if the textile material on a chair surface contains azo dyes and is not declared, it may be classified as a "dangerous product," leading to the detention or destruction of the entire shipment.
