CE marking is one of the most misunderstood requirements in international trade. Many Southeast Asian suppliers assume all aluminum products need CE certification to enter the European market, but this is not accurate. The reality is more nuanced, and understanding when CE marking applies can save your business significant time and money.
The European Union's CE marking system is a self-declaration of conformity that indicates a product meets EU safety, health, and environmental protection requirements. It is mandatory only for products covered by specific EU directives or regulations [1]. For aluminum alloy products, the key determining factor is intended use, not material composition alone.
For sandwich panels and aluminum alloy building materials specifically, CE certification becomes mandatory when the product is intended for permanent incorporation in construction works. This includes structural components like load-bearing aluminum frames, beams, and columns; building envelopes such as curtain walls, facades, and roofing systems; and safety-critical elements including fire-resistant panels and structural glazing systems.
The EN 1090-1 standard defines four execution classes (EXC1-EXC4) based on structural complexity and risk level. EXC1 covers simple structures like agricultural buildings, while EXC4 applies to high-risk structures like bridges and stadiums [4]. Most aluminum alloy sandwich panels for commercial buildings fall under EXC2 or EXC3.
European directives are the law, and they are available for free. The test standards used to evaluate and test your product are what cost money [5].
