Short answer

Manufacturers ensure that products are designed, assessed, and manufactured in compliance with all applicable requirements. Outsourcing design or production normally does not transfer this responsibility.

Key takeaways

  • Assign responsibility and define product version
  • Identify legislation and essential requirements
  • Perform risk and conformity assessment
  • Control supplier evidence and testing
  • Complete documentation, marking, and declaration
  • Monitor production, complaints, and product changes

Own name or brand may create manufacturer responsibility

A business that manufactures, has a product manufactured, or markets it under its own name or trade mark is normally the manufacturer. Substantial modification may also create new manufacturer responsibility.

From requirements to series production

Manufacturers assess legislation, control risks, perform the correct conformity procedure, prepare technical documentation and the EU declaration, and ensure marking, instructions, and production control.

Evidence must match the product sold

Identification, drawings, BOM, risk assessment, standards, testing, and changes should form one coherent chain. Series production must continue to match the assessed design.

Responsibility falling between functions

Common failures include unclear product ownership, documents not updated after changes, reliance on component certificates, and no post-market process.
