Product law is a complex, primarily European cross-sectoral area of law. Responsible economic operators must ensure compliance with the extensive legal requirements in their respective target markets.

Compliance & ESG

Establishing and maintaining a compliance system is increasingly becoming standard practice for businesses. Sustainability is becoming the guiding principle of economic activity.
