Overview

Under the EU Machinery Regulation, "related products" is not a catch-all label. It covers five named product families: interchangeable equipment, safety components, lifting accessories, chains, ropes and webbing for lifting, and removable mechanical transmission devices. Partly completed machinery sits beside those categories and needs a separate boundary decision because it follows incorporation documentation rather than the normal CE-marked related-product path.

Section 1

Classify the product before choosing the compliance route

Start with the category definition, not the sales name. A retrofit attachment may be interchangeable equipment if the operator fits it after machinery is put into service to change or add a function, but a normal tool is outside that definition. A component is a safety component only when it is placed independently on the market for a safety function and its failure or malfunction would endanger persons.

Lifting accessories, lifting chains, lifting ropes, and lifting webbing should be checked against their lifting purpose and placement in the load path. Removable mechanical transmission devices need their own check because the Regulation treats a device placed on the market with its guard as one item.

  • Record the selected category: interchangeable equipment, safety component, lifting accessory, lifting chain, lifting rope, lifting webbing, or removable mechanical transmission device.
  • Capture the facts that prove the category: intended function, whether it is independently placed on the market, whether it is fitted by the operator, whether it holds or transmits load or power, and whether a guard is supplied with the product.
  • Escalate separately if the assembly cannot perform a specific application by itself and is intended only for incorporation into other machinery, because that points to partly completed machinery rather than a related product.
Section 3

Build the technical file around the chosen category

For machinery and related products, the technical documentation should show the intended use, risk assessment, applicable essential health and safety requirements, protective measures, design drawings, standards or other technical specifications used, test and inspection evidence, production controls, instructions, declarations, and series-production measures.

For safety components and digital or software-enabled safety functions, preserve enough design, validation, version, and change-control evidence to explain the safety function and the consequences of failure. Where source code or programming logic is relevant to checking compliance, the Regulation allows competent authorities to request it when necessary.

  • Link each related-product category decision to the applicable essential health and safety requirements and the design measures used to meet them.
  • Include applied harmonised standards or other specifications, and specify the parts applied when standards are only partially used.
  • Keep test reports, design calculations, inspections, declarations from incorporated products, instructions for use, and production conformity controls in the same evidence package.
Section 4

Release checks for CE marking, declarations, and instructions

Before a related product is placed on the market or put into service, confirm that the technical documentation exists, the relevant conformity assessment has been completed, the EU declaration of conformity is available, and the CE marking is affixed visibly, legibly, and indelibly unless the product nature requires packaging or accompanying-document placement.

Digital instructions can be used under the Regulation when the access route is marked, the user can print and download them, and they remain accessible online for the required period. For related products that may be used by non-professional users, essential safety information for putting the product into service and using it safely must be provided on paper.

  • Check that the EU declaration of conformity identifies the related-product model and is kept with the technical documentation.
  • Verify that instructions identify the product model, are clear and legible, and are in a language determined by the relevant Member State.
  • Do not rely on voluntary certificates as proof of EU harmonisation compliance; the Commission machinery page warns that such certificates are not a recognised means to prove compliance in authority or customs checks.
Recommended next step

Classify machinery-related products before release

Turn category decisions, CE marking checks, declarations, instructions, and technical-file evidence into a repeatable review for engineering, regulatory, quality, and procurement teams.
