South Korea's Ministry of Climate, Energy and Environment (MCEE) began early implementation of a temporary special registration procedure under K-REACH on April 10, 2026, giving companies hit by raw-material shortages a faster route to bring in substitutes. Under the new arrangement, importers can submit a testing plan in place of certain hazard test data at the time of application, with the full data to follow later. That means they no longer have to wait the usual months for toxicology results before clearing K-REACH registration.
The move comes in response to supply-chain bottlenecks linked to the Middle East conflict, which have tightened supplies of petrochemical feedstocks including naphtha.
The registration hurdle
Under K-REACH, a chemical substance must be registered before it can be imported into Korea, and compiling the required toxicity and other test data typically takes three months or more. That timeline becomes a real constraint when a key raw material is suddenly disrupted — as has happened with naphtha and other petrochemical feedstocks amid the Middle East tensions — leaving downstream manufacturers unable to quickly switch to alternative overseas sources or bring in substitutes. The temporary provision is the government's answer to that problem: shortening the registration timeline for substances caught in the crunch.
How the fast track works
Instead of requiring the full set of hazard test results upfront, the procedure allows registrants to submit a testing plan covering physicochemical properties, human-health hazards and environmental hazards, and move forward with the registration while the actual test data is completed by a set deadline. Registrants are still required to hand over any test documents they already have. The effect is that a registration which would otherwise be held up by data collection can now be reviewed and granted while testing runs in parallel, on condition that the outstanding data is delivered later.
Who is eligible
This relief is not available to all K-REACH registrations. It is limited to specific supply-crisis substances for which the Minister of Trade, Industry and Energy, in consultation with the MCEE, has requested the special procedure. The amendment sets out the qualifying events — war, international disputes, or trade-restriction measures imposed by trading partners that cause or threaten serious disruption to a chemical's import or supply — and restricts the special procedure to a temporary run through December 31, 2027.
The procedure is contained in a partial amendment to the Enforcement Rules of the Act on Registration and Evaluation of Chemical Substances (K-REACH), which the government plans to finalise within April. Companies looking to bring in a substitute for a disrupted raw material should check whether their substance has been designated, put together the testing plan along with any data already in hand, and apply through the fast-track route so that registration does not become the bottleneck in their supply-chain switch.
What it means for industry
The MCEE expects the measure to help petrochemicals, coatings and plastics — sectors that rely heavily on imported raw materials — secure alternative feedstocks and avoid production stoppages. The special procedure extends an existing temporary provision under the K-REACH Enforcement Rules and will remain in place until December 31, 2027.
In effect, K-REACH now has a temporary pressure-release valve for crisis-driven substitutions — but only for substances designated through the inter-ministry process, only in response to the qualifying events, and only until the end of 2027. Affected importers would be wise to act while the window is still open.
