Act on the Registration and Evaluation of Chemical Substances (K-REACH)

Chemicals management in South Korea is currently undergoing a major overhaul. The Act on the Registration and Evaluation of Chemicals (AREC), also known as K-REACH, took effect from 1 January 2015. Currently the Act requires manufacturers and importers of:

  • new substances* to register before manufacture/import and;
  • priority existing substances (PECs) to register before 30 June 2018.

Currently, K-REACH also requires manufacturers, importers and sellers to report information about substances to the South Korean Ministry of Environment (MOE). The tonnage limit for reporting existing substances is 1 tonne/year or more, but there is no limit for new substances. K-REACH also regulates products and products of risk concern. The definition and management of ‘products’ under K-REACH is distinct from that of ‘articles’ under REACH.

At the end of 2016, the MOE proposed plans to significantly amend the regulation and introduce registration deadlines for all existing substances ≥ 1 tonne/year. The revised Act is expected to closely mirror REACH, adopting many of the same concepts (including pre-registration) and regulating both new and existing substances under a single system.

*New substances are defined as substances that are not on the Korean Existing Chemicals List (KECL).
