On January 15, 2025, the South Korea’s Ministry of Environment (MoE) issued the updated list of pre-registered substances under K-REACH. As of December 31, 2024, a total of 249,371 pre-registration or late pre-registration applications were submitted for 17,533 chemical substances, of which 77 are CMRs substances. About 8.8% of the pre-registered substances are manufactured or imported over 1,000 t/y.
Under K-REACH, pre-registered substances are granted a grace period to manufacture/import chemicals before the corresponding phase-in registration deadline. Corresponding registration deadlines are set as below:
1,000 t/y; or designated 364 CMRs above 1t/y: by December 31, 2021
100-1,000 t/y: by December 31, 2024
10-100 t/y: by December 31, 2027
1-10 t/y: by December 31, 2030
2,785 substances were pre-registered with a maximum tonnage band within 100-1,000 t/y, accounting for about 15.6% of the pre-registered substances. They should complete joint registration before the second registration deadline as of December 31, 2024. The next registration deadline is on December 31, 2027, targeting pre-registered substances with the maximum tonnage band within 10-100 t/y. MoE urges the stakeholders involved with these substances to timely join the consortium and ensure the registration work.
For each pre-registered substance, the MoE provides information including:
