EU Machinery Regulation Annex I high-risk categories
to Regulation (EU) 2023/1230 lists machinery and related product categories that receive a special conformity-assessment route because of their inherent potential risk.
This page helps distinguish Part A from Part B, identify the listed category, and keep the evidence that supports the selected conformity-assessment route.
lists machinery and related product categories that receive the Article 25 conformity-assessment procedures reserved for higher-risk categories. Annex III contains the essential health and safety requirements. The Annex I decision tells the manufacturer which assessment route must be used before CE marking and the EU declaration of conformity.

Section 1
What Annex I means under Regulation (EU) 2023/1230
Article 6 divides into Part A and Part B. Part A categories must use one of the Article 25(2) procedures. Part B categories use Article 25(3), where internal production control is available only when the product is designed and constructed in accordance with harmonised standards or common specifications specific to that category and covering all relevant essential health and safety requirements.
The Regulation also explains how categories can be added, removed, or moved between parts. The Commission assesses the seriousness of inherent potential risk using probability of harm and severity of harm, with criteria such as hazard nature, persons affected, exposure, avoidability, safety-component failure consequences, accident data, close calls, market surveillance findings, and uncertainty in risk assessment methods for new technologies.
The current consolidated Regulation also contains Articles 25a to 25e for an activated internal market emergency. Those provisions apply only when the internal market emergency mode has been activated under Regulation (EU) 2024/2747, the Commission has adopted an implementing act for machinery or related products, and the product has been designated as crisis-relevant. They do not change whether a product belongs in and are not a standing alternative to the normal Article 25 route.
Do not treat every Annex III essential health and safety requirement as an high-risk category; Annex I is a category trigger for conformity assessment.
Use the exact item text, product configuration, intended use, and foreseeable misuse when classifying a product.
Keep the category decision separate from the technical design evidence that proves conformity with Annex III.
Recheck the current text when the assessment is approved or renewed because Article 6 allows the Commission to add categories, remove them, or move them between Part A and Part B by delegated act.
If a team relies on an emergency procedure, retain the activating EU act, the crisis-relevant product designation, any national authorisation, its territorial and time limits, traceability conditions, and the post-emergency action required for products already placed on the market.
Article 6 and Annex I define the listed categories, allow categories to be added, removed, or moved between Part A and Part B by delegated act, and link both parts to the Article 25 conformity-assessment routes.

Section 2
Part A categories and the mandatory third-party routes
Part A contains a short list: removable mechanical transmission devices including their guards; guards for removable mechanical transmission devices; vehicle servicing lifts; portable cartridge-operated fixing and other impact machinery; safety components with fully or partially self-evolving behaviour using machine learning approaches ensuring safety functions; and machinery with embedded systems with such self-evolving behaviour ensuring safety functions, in respect only of those systems.
For these Part A categories, Article 25(2) does not offer Module A internal production control. The manufacturer, or the person responsible for a substantial modification under Article 18, must use EU type-examination followed by conformity to type, full quality assurance, or unit verification.
Record whether the product is the listed machinery, a related product, an independently placed safety component, or an embedded safety-function system inside the machinery.
If Part A applies, identify the selected procedure as Module B plus Module C, Module H, or Module G.
If the classification depends on machine-learning self-evolving behaviour, document the safety function, whether the component is independently placed on the market, and the product boundary covered by the decision.

Section 3
Part B categories and when internal production control is enough
Part B carries the longer list. It includes specified woodworking and meat-processing saws, hand-fed planing and tenoning machinery, thicknessers, bandsaws, combined woodworking machinery, portable chainsaws, certain metalworking presses, injection or compression plastics and rubber moulding machinery with manual loading or unloading, specified underground-working machinery, manually loaded household refuse trucks with a compression mechanism, lifting devices for persons or persons and goods involving a vertical fall hazard of more than 3 m, protective devices detecting persons, certain power-operated interlocking movable guards, logic units for safety functions, roll-over protective structures (ROPS), and falling-object protective structures (FOPS).
Part B does not automatically require a notified body in every case. Article 25(3) permits Module A internal production control only where harmonised standards or common specifications specific to the category cover all relevant essential health and safety requirements and have been applied for design and construction. If that full coverage and application cannot be shown, the route changes to Module B plus Module C, Module H, or Module G.
Quote the specific Part B item number and the words that match the product, such as manual loading or unloading, vertical fall hazard over 3 m, or safety-function logic unit.
For Module A, keep a standards coverage matrix showing the harmonised standards or common specifications, publication references, applied parts, and the Annex III requirements they cover.
Where standards are absent, partial, not applied, or not category-specific, document why a notified-body route is being used instead of Module A.

Section 4
How to document the category decision
A usable record should let a reviewer reproduce the classification without knowing the project history. Start with the product boundary, model or configuration, intended use, foreseeable misuse, market role, and whether the item is machinery, a related product, a safety component, or partly completed machinery.
Then attach the item analysis, the Article 25 route, and the evidence behind that route. For a Part B Module A route, the key evidence is the standards or common specifications coverage. For notified-body routes, keep the application, technical documentation, certificates, reports, quality-system decisions, and any changes or certificate reviews that affect the approval.
Store the item number, quoted category text, matching product facts, exclusions considered, and final route.
Keep risk assessment documentation, Annex III EHSR mapping, drawings and schemes, applied standards or other specifications, design calculations, tests, inspections, examinations, instructions for use, declarations, and production-control evidence.
For safety-related software, sensor-fed, remotely driven, or autonomous machinery, retain the source-code or programming-logic response basis and the system characteristics, capabilities, limitations, development, testing, and validation records described in Annex IV where applicable.
For legacy Machinery Directive files, preserve the old Annex IV classification and conformity-assessment evidence separately from the Regulation decision so transition reviews do not mix the two lists.

Document the Annex I route before release
Turn the Annex I category decision into a reusable classification record with the product facts, Article 25 route, standards coverage, notified-body evidence where needed, and technical-file references.
The main error is using a broad label such as high-risk machinery without tying it to an item and an Article 25 route. The Regulation's list is category-specific. A category decision should be based on the listed product type and its characteristics, not on a general view that the machine is dangerous.
Another recurring problem is confusing the Regulation's with the Machinery Directive's Annex IV. The legacy guide is still useful for understanding Directive classifications, but Regulation (EU) 2023/1230 moved the listed high-risk categories into Annex I and changed the legal route references.
Do not use a voluntary certificate from a body outside its notified scope as proof of conformity.
Do not select Module A for a Part B product unless the standards or common specifications are specific to that category and cover all relevant Annex III requirements.
Do not treat a safety component, an embedded safety-function system, and complete machinery as interchangeable classifications.
Do not bury the category analysis inside a generic risk assessment; the item and Article 25 route should be explicit.
