Recently, the Republic of Korea's Ministry of Climate, Energy and Environment (MCEE, formerly the Ministry of Environment), pursuant to Article 42 (Disclosure of Chemical Substance Information) of the Act on the Registration and Evaluation of Chemicals (K-REACH) and Article 51 (Disclosure of Chemical Substance Information, Etc.) of its Enforcement Rule, updated and released the pre-registration (sajeon-singo) results list for existing chemical substances for the second quarter of 2026 (data as of June 30, 2026).
According to the list, as of June 30, 2026, a total of 17,723 existing chemical substances (counted by KE No., the Korea Existing Chemicals Inventory number) hold valid pre-registration records. The disclosed information covers company-reported manufacture/import tonnage bands, CMR (carcinogenic, mutagenic, or toxic to reproduction) status, and consumer-use status, among other items.
The tonnage band distribution is as follows:
- 1–10 t/year: 6,877 substances
- 10–100 t/year: 6,883 substances
- 100–1,000 t/year: 2,442 substances
- ≥1,000 t/year: 1,521 substances
Under K-REACH, existing chemical substances manufactured or imported in quantities of ≥1 tonne per year are subject to pre-registration, and must subsequently complete formal registration in phases, with deadlines determined by their tonnage band.
