Product Safety / Compliance / Approval Processes
We cover the entire product development process to ensure a smooth market entry. This includes, among other things:
- Product Classification & Certification Strategy: We define the right path for your product. We identify the applicable requirements and determine how compliance with them will be achieved.
- Required Documentation: Support with risk analyses, operating instructions, product labeling, and declarations of conformity. This creates robust records that meet the requirements of completeness and adequacy.
- Usability (UX): Tests to determine the user-friendliness of your products. This is required by law, improves customer reviews, and facilitates sales.
- Type Approvals: We support EC type approvals until approval is granted and subsequent requirements are met.
- Examples of product groups: Machinery, toys, low-voltage products, construction products, motor vehicles, battery- or radio-operated products, clothing, furniture, tools, PPE, batteries, AI products, medical devices, bicycles, and e-bikes.
Proof of suitability as a manufacturer / quality management systems
- Requirements assessment: We find the right quality management system for your company (ISO 9001, KBA initial assessment, ISO 13485, etc.). In addition to your own requirements, the requirements arising from your products are recorded and incorporated into an integrated management system.
- Implementation: Creation, audit, and revision of your quality management system until certification readiness and recertification.
- Certification support: We support you throughout the entire certification process.
Assumption of manufacturer obligations / Authorized representative
- Authorized EU representative: Appointing an authorized representative for the EU is mandatory for products from third countries. In other cases, authorization may be advantageous. We act as your official representative in the EU in all matters, completely relieving you and your customers of any burden.
- Legally compliant distribution: Our network secures your distribution throughout the EU.
- Protection of trade secrets: We protect your interests and confidential data.
Production Quality and Suitability Testing

- Additional Services: Support with product recalls, trade fair participation, and sales.
Training courses and seminars
Training: We offer lectures and seminars on our services covering relevant EU directives, EU regulations, manufacturer obligations, CE compliance, product safety, and quality management. Our seminars are specifically aimed at responsible persons, CE and QM representatives, designers, and purchasers.

FAQ
We already have a CE test certificate from TÜV; is that sufficient?
No. A test certificate or a TÜV certificate can be helpful, but it does not replace the legally required EU Declaration of Conformity (DoC). This DoC is necessary to be able to affix the CE marking. Accredited testing bodies do not issue DoCs. We can assist you with this: We will review the applicable directives, prepare the necessary documentation, draft the declaration of conformity, and support you throughout the entire conformity assessment process and beyond.
I have a declaration of conformity; does that mean my product is market-ready?
No. In addition to a declaration of conformity, some directives require that your company has an appropriate quality management system in place.
If you already have a quality management system, we would be happy to review it to determine whether it meets the requirements for your new product.
We would also be pleased to assist you in implementing an appropriate quality management system.
