Overview

MSR investigations are operationally predictable: authorities run risk-based checks, request documentary evidence, and may escalate to physical/lab checks. What changes outcomes is not "having documents somewhere", but being able to produce the right evidence quickly, in the right structure, with clear versioning and traceability - and being able to execute corrective actions when evidence shows non-compliance or risk.

Section 1

1) How authorities conduct checks (Article 11)

Authorities work on a risk basis, but the available power set is broad. The investigation may begin as a document check and quickly expand into testing, site access, online-interface measures, or customs coordination.

Prepare for that expansion from the start instead of treating the first request as an isolated email.

Assume cross-border reuse: make evidence pack structure consistent and easy to interpret.
Keep a product-family dossier: what changed, when, and why (design, supplier, software, labeling, standards).
Treat marketplace and ecommerce as first-class channels: online and offline checks are explicitly in scope (Article 11(1)(a)).

Section 2

2) What evidence is typically requested

Article 4 economic operator tasks explicitly include verifying that declarations and technical documentation have been drawn up and ensuring technical documentation can be made available on request (Article 4(3)(a)). Authorities can request all information and documentation necessary to demonstrate conformity (Article 4(3)(b)).

In practice, evidence requests usually aim to answer four questions: what is the product, what rules apply, what evidence shows conformity, and what actions are taken when risk/non-compliance exists.

Expect requests for declarations, technical documentation, tests, supply-chain information, quantities on the market, and information about technically similar models.
Expect requests relating to website ownership and operator identity where online offers are in scope.
Where necessary for compliance assessment, expect requests for access to embedded software and related technical information.

Section 3

3) Confidentiality and procedural rights

Authorities must respect confidentiality, professional and commercial secrecy and protect personal data (Article 17). At the same time, measures/orders must state grounds and be communicated; operators must be informed of remedies and time limits (Article 18(1)-(2)).

Before measures are taken, operators generally get an opportunity to be heard for at least 10 working days unless urgent (Article 18(3)). Build your response process around these procedural expectations.

Secure sharing: define channels for confidential evidence and how you track who received what.
Redaction policy: separate trade secrets from required conformity evidence; justify redactions consistently.
Response governance: single case owner, clear approvals, and a fixed evidence pack structure.

Section 4

4) Data-sharing and coordination (Article 34)

Article 34 is the structured system behind requests for information, measures, testing, and corrective action. Evidence from one Member State can shape action in another, and customs-related cases also feed into the same coordinated layer.

This is why product-family evidence indexing matters more than ad hoc case folders.

Keep your evidence pack versioned and immutable after submission; issue addenda instead of overwriting.
Align internal incident IDs with external case IDs for traceability.
Maintain a "what we told authorities" register per product family.
