Regulatory Compliance: New EU Requirements for 2025-2026

This section is critical for Southeast Asian exporters. The European Union implemented major regulatory changes in 2025 that directly affect structural aluminum imports. Non-compliance means your products cannot be legally sold in the EU market, regardless of quality or price.

Construction Products Regulation (CPR) 2024/3110 replaced the previous 305/2011 regulation on January 7, 2025. For structural aluminum suppliers, this means three new mandatory requirements:

1. Declaration of Performance and Conformity (DoPC): Manufacturers must provide a formal declaration stating the product's performance characteristics (mechanical properties, fire resistance, corrosion resistance) and confirming conformity with harmonized European standards (EN 755, EN 12020 for extruded products).

2. Environmental Sustainability Declaration: Previously voluntary Environmental Product Declarations (EPD) are now mandatory. You must document the product's environmental impact throughout its lifecycle, including carbon footprint, recyclability, and hazardous substance content.

3. Digital Product Passport (DPP): Each product batch must have a digital record containing material composition, manufacturing process, test certificates, and traceability information. This enables buyers and regulators to verify compliance instantly.

RoHS Directive Update (EU) 2025/2364: Published November 2025, this amendment affects aluminum alloys containing lead as a machining aid. While 6082 typically contains minimal lead (less than 0.10%), suppliers must verify and declare compliance with the updated exemption thresholds.

European Aluminium provides over 120 European standard usage guides and catalogs covering chemical composition, technical delivery requirements, and mechanical property testing methods. EN AW-6082 falls under EN 755/EN 12020 extruded product standards, with CE marking required under CPR 2024/3110. ^[3]

prEN 15088 is the emerging European standard for conformity assessment of aluminum structural products. It specifies performance characteristics and evaluation requirements for semi-finished structural aluminum building products. Suppliers targeting the construction sector should familiarize themselves with this standard's testing protocols.
