Short answer
China RoHS applies to covered electrical and electronic products produced, sold, or imported in China. It requires China-specific hazardous-substance information and marking, and adds substance-limit and conformity-assessment duties for products in the compliance-management catalogue.
EU RoHS applies to electrical and electronic equipment in the Annex I categories, subject to Article 2 exclusions. It restricts Annex II substances at homogeneous-material level, subject to applicable exemptions, and requires technical documentation, an EU declaration of conformity, and CE marking before covered equipment is placed on the EU market.
Articles 2, 3, and 9 to 18 establish the China scope, roles, marking and disclosure, catalogue, and conformity-assessment structure.
Articles 2 to 4 and 7 to 16 establish EU scope and exclusions, homogeneous-material limits, exemptions, economic-operator duties, technical documentation, EU declaration of conformity, and CE marking.
Current official consolidation used to verify the EU scope, homogeneous-material rule, operator duties, and Annex III and IV exemption text and dates.
