A part can pass every dimensional check, clear inspection, and still get turned away at a European port because the paperwork behind the CE mark was assembled wrong.
This comes down to the regulation applied, which conformity route the product needs, and whether the technical file can actually stand up to a market surveillance request.
For manufacturers of structural steel, aluminium assemblies, machinery components, and fabricated metal goods, CE certification is not one certificate you apply for once. It is a compliance framework that shifts depending on what the product is, how it will be used, and which EU legislation governs it. This guide walks through what CE marking requires for metal products specifically, how the process works step by step, and what changes manufacturers need to prepare for before 2027.
What Is CE Certification and Why Does It Matter for Metal Products?
CE marking is a manufacturer's declaration that a product meets the relevant EU health, safety, and environmental legislation before it enters the EU or EEA market.
But there is no single "CE certificate." The European Commission's own guidance frames CE marking as a self-declaration process backed by evidence, not a quality stamp issued by an authority.
For metal manufacturers, this matters because CE marking only applies where a product category falls under specific EU harmonisation legislation. A fabricated bracket supplied solely as an industrial component may fall outside CE marking requirements, while that same bracket incorporated into a structural construction product or machine may fall within scope.
The same bracket, welded into a structural frame destined for a building site, almost certainly does. Getting this classification right could avoid most delays.
Which Metal Products Actually Require CE Marking?
The legislation that applies depends entirely on end use, not material. A few categories cover most of what manufacturers in precision fabrication and metalwork will run into.
- Structural steel and aluminium components used in construction fall under the Construction Products Regulation, enforced through the harmonised standard EN 1090.
- Machinery, partly completed machinery, and safety components fall under the Machinery Regulation.
- Electrical enclosures or assemblies with electrical elements may additionally trigger the Low Voltage Directive or EMC Directive.
A single product can sit under more than one piece of legislation simultaneously, and each one carries its own essential requirements and assessment route. And identifying every applicable regulation before design freeze is significantly cheaper than discovering a gap after tooling is committed.
What Is the Machinery Regulation (EU) 2023/1230, and Why Should Fabricators Care Now?
If your metal products feed into machinery, industrial equipment, or automated systems, this is the regulation to watch.
Regulation (EU) 2023/1230 replaces the Machinery Directive 2006/42/EC and becomes fully applicable on 20 January 2027, after which all machinery placed on the EU market must comply with the new regulation rather than the old directive.
The change is more than a name swap. The new regulation extends coverage to categories the old directive barely touched, including autonomous mobile machinery, AI-based safety systems, cobots, and equipment with remote operation or connectivity features.
Risk assessments will need to account for cybersecurity risk alongside the traditional mechanical, electrical, and ergonomic hazards, and documentation must show how those risks are controlled through the product's software and update lifecycle, not just its physical design. Manufacturers who assumed they sat outside machinery scope under the old directive should recheck that assumption against the new one.
There is also a practical shift worth flagging for anyone managing large documentation sets: the regulation permits digital instructions for use and electronic technical documentation, provided paper copies remain available on request and safety-critical information stays accessible. Manufacturers are generally required to retain technical documentation for at least ten years after the product is placed on the market or the last unit has been placed on the market, depending on the applicable legislation.
Takeaway: Since a 2027 deadline sounds distant until it isn't, manufacturers producing machinery components or partly completed machinery should treat this as a 2026 planning item, not a 2027 problem.
What Is EN 1090, and Why Does It Govern Most Structural Metal Fabrication?
For anyone welding, cutting, or assembling structural steel and aluminium, EN 1090 is the standard that actually determines whether CE marking is achievable at all. Under the Construction Products Regulation, CE marking of structural steelwork and aluminium became mandatory in July 2014, and it remains a legal requirement for supplying structural components to construction sites across the EU.
EN 1090 is a three-part standard. EN 1090-1 sets the conformity assessment requirements for CE marking itself. EN 1090-2 covers technical execution requirements for steel structures, and EN 1090-3 covers the equivalent for aluminium. Before a manufacturer can affix the CE mark, they need to determine which Execution Class (EXC 1 through EXC 4) their structures fall into, since the required rigor of Factory Production Control scales directly with that classification.
Factory Production Control (FPC) is where most of the operational work sits. It requires manufacturers to certify welding operations against the ISO 3834 series, maintain material traceability back to mill certificates, calibrate welding and measuring equipment on a schedule, and appoint a Responsible Welding Coordinator to oversee the welding function.
Unlike lower-risk product categories, EN 1090-1 requires that FPC be certified by an accredited Notified Body, not self-declared. That single detail changes both the timeline and the cost of getting a fabrication shop CE-ready, and it is often the point where manufacturers new to structural work are caught off guard.
How Does the CE Marking Process Actually Work?
Stripped down, the process the European Commission's Blue Guide sets out runs through five stages, and metal manufacturers should expect to work through all five even for a single product line.
- First, identify every EU regulation or directive that applies. A connected industrial control panel, for instance, could sit under the Machinery Regulation, the Low Voltage Directive, and EMC Directive at once.
- Then, identify the essential requirements each piece of legislation sets, and match them to the relevant harmonised standards published in the Official Journal of the EU.
- Select the correct conformity assessment route, which depends on the legislation and risk category, not manufacturer preference.
- After that, compile the technical file with the evidence needed to demonstrate compliance.
- Finally, draft and sign the EU Declaration of Conformity, then affix the CE mark to the product using the correct proportions and placement rules.
Skipping the sequence, particularly jumping to the technical file before confirming the assessment route, is one of the more common reasons documentation has to be redone.
Self-Declaration or Notified Body: Which Route Applies to Your Product?
Conformity assessment routes are structured as modules, ranging from Module A, full manufacturer self-assessment, through to Module H, full quality assurance with Notified Body involvement at every stage. Which module applies is set by the governing legislation itself, not chosen by the manufacturer.
Most machinery under the Machinery Regulation and most products covered by the Low Voltage Directive allow manufacturer self-assessment where applicable. The General Product Safety Regulation applies separately to consumer product safety but is not itself a CE-marking directive.
Structural steel and aluminium under EN 1090, by contrast, require third-party FPC certification regardless of how low-risk the specific product looks, because the standard itself mandates it.
When a Notified Body is required, verifying their credentials matters more than manufacturers sometimes assume. NANDO, the European Commission's public registry, lists every designated Notified Body along with the specific directives and modules they are authorised to assess. A body operating outside its NANDO designation cannot legally issue a valid conformity assessment for that product category, so this is worth checking before signing any engagement, not after.
What Needs to Go Into the Technical File?
The technical file is the evidence base that a product actually meets the requirements it claims to. Authorities can request it years after a product has shipped, and manufacturers must generally retain it for at least ten years after the last unit is placed on the market.
For fabricated metal products, a complete technical file typically includes a general product description and intended use, design and manufacturing drawings, a risk assessment covering the hazards specific to the product, references to the harmonised standards applied, test reports and material certificates, and instructions for use.
For EN 1090-governed structures, this extends to welding procedure specifications, welder qualification records, and FPC audit records tied to the declared Execution Class.
Takeaway: A folder of test reports is not automatically a technical file. It needs a clear narrative connecting product scope, applicable law, identified risks, the standards applied, and the supporting evidence, organized so a market surveillance authority can follow the logic without needing to ask.
What Is the EU Declaration of Conformity, and What Must It Include?
The Declaration of Conformity is the document that formally states a product complies, and it is signed only once the applicable conformity assessment is complete.
According to NIST's compliance guidance, it must identify the manufacturer, describe the product clearly enough to trace it back to the technical file, list every directive and regulation it complies with, reference the harmonised standards applied, name the Notified Body involved where applicable, and carry the signature of an authorized representative.
One product covered by multiple pieces of legislation can often be covered by a single consolidated Declaration, though certain sectors use distinct documents such as a Declaration of Performance for construction products. Getting the Declaration wrong, or issuing it before assessment is actually complete, invalidates the CE mark even if the product itself is fully compliant.
How Wootz.work Approaches CE Readiness in Practice
Wootz.work recently worked on a project to manufacture a CE-ready aluminium ride-on toy for a Belgian seed-stage startup.
No single local vendor could deliver the combination of high-pressure die casting, sheet-metal deep drawing, CNC pipe bending, aluminium welding, and precision machining the design required.
Rather than treating certification as a final checkpoint, material selection, edge finishing, and surface treatment were resolved with CE requirements built into the design from day one. That sequencing, engineering for compliance rather than testing for it afterward, took the project from concept to CE-ready prototype in three months while holding the startup's target pricing.
Building a Product That Needs to Be CE-Ready?
Wootz.work's engineering team designs for compliance from the first prototype, across structural fabrication, machinery components, and precision metal parts bound for the EU market.
Talk to Our Engineers TodayFrequently Asked Questions
What is CE certification?
CE marking is a manufacturer's declaration, backed by a technical file and a signed Declaration of Conformity, that a product meets the essential requirements of the EU legislation that applies to it. It is not issued by a government body and is not a quality endorsement. The CE mark confirms that the manufacturer has assessed the product against the relevant European requirements for safety, health, and environmental protection. Before placing a product on the EU market, manufacturers must be able to provide supporting technical documentation if requested by market surveillance authorities.
Do all metal products need CE marking?
No. CE marking only applies to product categories covered by specific EU harmonisation legislation. A component sold for further processing may fall outside scope, while the same part assembled into a structure or machine may require it. Whether a metal product needs CE marking depends on its intended use, how it is supplied, and which EU regulations apply. Identifying the applicable legislation early in the design process helps avoid costly redesigns, certification delays, and compliance issues later in the project.
What is the difference between CE marking and a CE certificate?
There is no legally recognized document called a "CE certificate." What exists are the Declaration of Conformity, the technical file, and, in some cases, a certificate issued by a Notified Body. "CE certificate" is informal trade language, not a legal term. Many buyers use the phrase when they are actually requesting compliance documentation. Understanding the difference helps manufacturers provide the correct documents during procurement, customer audits, and customs inspections.
Which products need a CE certificate?
The term "CE certificate" is commonly used, but the legal requirement is CE marking for products covered by specific EU harmonisation legislation. This includes categories such as machinery, construction products, electrical equipment, medical devices, pressure equipment, personal protective equipment, toys, and certain measuring instruments. Not every metal product requires CE marking. Whether it is mandatory depends on the product's intended use and the EU legislation that applies to it. For example, structural steel products under EN 1090 and many finished machines require CE marking, while raw materials and many semi-finished metal components do not.
What does CE mean on metal?
A CE mark on a metal product means the manufacturer declares that the product complies with all applicable EU safety, health, and environmental requirements. It allows products covered by relevant EU legislation to be legally placed on the European Economic Area (EEA) market. The mark does not indicate where the product was manufactured or guarantee its quality. Instead, it confirms that the manufacturer has completed the required conformity assessment and prepared the necessary technical documentation.
How can I get a CE certificate?
Manufacturers do not apply for a single government-issued "CE certificate." Instead, they identify the applicable EU legislation, assess the product against the relevant requirements, compile a technical file, prepare an EU Declaration of Conformity, and affix the CE mark where permitted. Some products can be self-declared, while others require testing or assessment by a Notified Body before CE marking is allowed. The correct process depends entirely on the product category and the legislation that applies.
What happens if you sell without CE marking?
If a product that legally requires CE marking is sold without it, authorities can prevent it from entering or remaining on the EU market. Products may be stopped at customs, recalled from customers, withdrawn from sale, or subject to enforcement action. Manufacturers, importers, and distributors may also face fines or legal liability depending on the member state's enforcement rules. Beyond regulatory consequences, missing CE marking can delay shipments, damage customer relationships, and prevent access to European markets.
What products do not need CE marking?
Products that are not covered by EU harmonisation legislation do not require CE marking. This often includes raw materials, many industrial components supplied for further processing, custom-made parts that fall outside specific legislation, and products intended for markets outside the European Union. However, manufacturers should never assume a product is exempt based solely on its material or industry. The intended use and applicable legislation determine whether CE marking is required.
How do I know if a product is CE certified?
A compliant product will normally display the CE mark and be supported by an EU Declaration of Conformity. Depending on the product, manufacturers should also be able to provide technical documentation and, where applicable, evidence of Notified Body involvement. If you're purchasing a product, ask the manufacturer or supplier for the Declaration of Conformity rather than simply requesting a "CE certificate." That document provides the legal basis for the CE marking claim.
Can I CE mark my own product?
Yes, many products can be CE marked through manufacturer self-declaration if the applicable legislation allows it. This means the manufacturer is responsible for demonstrating compliance, preparing the technical file, carrying out the required conformity assessment, and issuing the Declaration of Conformity. Self-declaration does not make the process less rigorous. The manufacturer remains legally responsible for ensuring the product meets all applicable EU requirements and for providing evidence if requested by authorities.
What is the difference between ASTM and CE?
ASTM and CE serve different purposes. ASTM develops voluntary technical standards that specify how materials, products, and test methods should perform, while CE marking is a legal requirement under European Union legislation that demonstrates a product complies with applicable regulatory requirements. Manufacturers often use ASTM standards during design, testing, or manufacturing while still completing the separate CE conformity assessment required to sell products in the European market. Meeting an ASTM standard does not automatically qualify a product for CE marking.
Is CE certification mandatory?
Yes, but only for products covered by applicable EU harmonisation legislation. If a product falls within the scope of those regulations and is placed on the European Economic Area (EEA) market, CE marking is a legal requirement. If the legislation does not apply to a product, CE marking is neither required nor permitted. Applying a CE mark to a product that falls outside the relevant legislation can itself be considered non-compliant.
Do I need a Notified Body for CE marking?
It depends on the governing legislation. Many machinery and general product categories allow self-declaration under Module A. Structural steel and aluminium under EN 1090 require third-party Factory Production Control certification regardless of risk level. Some higher-risk products also require assessment by a Notified Body before they can be placed on the EU market. Identifying the correct conformity assessment route early helps avoid unexpected certification delays and unnecessary redesign work.
How long does CE certification take for a metal product?
It varies by legislation and Execution Class, but building compliance into the design from the outset, rather than testing for it after production, is consistently the biggest factor in the timeline. Projects that treat certification as a late-stage checkpoint tend to take longer and incur higher costs. The overall timeline also depends on product complexity, testing requirements, technical documentation, and whether third-party assessment is required. Planning for CE compliance during engineering usually results in faster approvals and smoother production.
What happens when the new Machinery Regulation takes effect in 2027?
From 20 January 2027, all machinery placed on the EU market must comply with Regulation (EU) 2023/1230 instead of the outgoing Machinery Directive. Manufacturers producing machinery and certain machinery-related products should review product scope, risk assessments, technical documentation, and conformity assessment procedures well before that date. The new Machinery Regulation introduces updated requirements to address modern technologies such as software-driven machinery, artificial intelligence, connected equipment, and cybersecurity risks. Although many of the existing safety principles remain, manufacturers may need to update product documentation, operating instructions, risk assessments, and compliance processes to meet the new regulation. Companies that begin preparing early are more likely to avoid launch delays, failed audits, customer approval issues, and disruptions to selling products within the European Union.
How long do I need to keep CE marking documentation?
Technical files and Declarations of Conformity generally need to be retained for at least ten years after the last product is placed on the market. Keeping complete and well-organized records is important because EU market surveillance authorities may request them years after a product has been sold. Good documentation also makes future product updates, customer compliance requests, audits, and regulatory inspections much easier to manage.
What documents are required for CE marking?
The exact requirements depend on the product and the legislation that applies, but manufacturers typically need a technical file, risk assessment, design and manufacturing records, test reports where applicable, user instructions, and a signed EU Declaration of Conformity. These documents demonstrate that the product complies with the relevant EU requirements and must be available if requested by market surveillance authorities. Proper documentation is just as important as the CE mark itself because it provides the evidence behind the manufacturer's compliance claim.
