The revised K-REACH took effect on January 1, 2019, adopting new registration mechanisms in South Korea. Pre-registration for existing chemicals is necessary to be eligible for the phase-in registration grace period. Phased-in registration should be complied with based on tonnage band by 2030. The first deadline of 31 December 31, 2021 for existing chemicals manufactured/imported in quantities of 1,000 tonnes per year or more is approaching. Many enterprises have been preparing for the joint registration. This webinar will introduce the procedures and requirements of K-REACH joint registration, as well as data sharing on chemicals.
