Polymers with number average molecular weight between 1,000 and 10,000, containing less than 25% of molecules below 1,000 and less than 10% below 500. To qualify for exemption, manufacturers must submit a confirmation of exemption demonstrating compliance.• Polymers Requiring Registration include cationic polymers or polymers with number average molecular weight below 10,000 where unreacted monomers classified as hazardous, subject to intensive control, or non-phase-in substances exceed 0.1% by weight .• Hazard Review and Risk Assessment under K-REACH requires evaluation of chemical substances deemed necessary, including those assessed by international organizations (OECD), substances for international convention implementation, nanomaterials, and substances that may harm human health or the environment. The Ministry of Environment conducts risk reviews considering hazards, uses and exposure information, and socio-economic impacts.• Substances Subject to Permission are designated by the Minister of Environment following candidate selection, public announcement, and risk review.

Manufacturers and downstream users must comply with permitting requirements for designated substances.
