For Southeast Asian manufacturers looking to sell on Alibaba.com and reach European construction buyers, understanding CE certification requirements is not optional—it's the foundation of market access. CE marking indicates that a product meets EU safety, health, and environmental protection requirements, and for aluminum construction products, this primarily falls under EN 1090-1 standard.
EN 1090-1 has been mandatory since July 1, 2013, for all load-bearing steel and aluminum structures placed on the European market. The standard defines four Execution Classes (EXC) that determine the level of certification required: EXC1 for agricultural buildings and simple structures, EXC2 for residential and commercial buildings, EXC3 for bridges and high-rise structures, and EXC4 for stadiums and other exceptional structures. Most aluminum window, door, and facade suppliers targeting European buyers will need EXC2 or EXC3 certification [1].
The certification process involves multiple stakeholders. Manufacturers must establish a Factory Production Control system, undergo initial inspection by a Notified Body (for EXC2-4), and maintain ongoing surveillance. The Declaration of Performance (DoP) is a legal document that must accompany each product batch, specifying the product's characteristics and performance levels. Without a valid DoP and CE marking, customs authorities can seize shipments at EU borders—a risk that has materialized for many importers who relied on fake certificates from unverified suppliers.
Many factories just supply fake CE certificates. They may not have one yet and are asking you to place an order so they do testing. As an importer, you are liable if a customer gets injured or a house burns down. [6]
This Reddit comment from an experienced sourcing professional highlights a critical reality: CE certification cannot be outsourced to suppliers without verification. When you rebrand or private-label products, EU law legally defines you as the manufacturer, making the factory's CE certificate insufficient on its own. You must issue your own Declaration of Conformity and maintain technical documentation for 10 years [7].
