The third round of LR election for priority existing chemical substances (PECs) under K-REACH finished in Mar of 2016. So far LR election has been completed for 169 PECs. The election results were made public, including CAS No., chemical name, date of LR determination, and the name of LR.
The third round of LR election includes 16 PECs. The details are specified as below.
| CAS No. | Chemical Name | Date of LR Election |
| 79-94-7 | 4,4'-(1-Methylethylidene)bis[2,6-dibromophenol] | 3 Mar 2016 |
| 7439-92-1 | Lead | |
| 7440-43-9 | Cadimium | |
| 7173-51-5 | Didecyldimethylammonium chloride | |
| 92-52-4 | 1,1'-Biphenyl ; Diphenyl ; Phenylbenzene | |
| 7697-37-2 | Nitric acid ; Aqua fortis | 11 Mar 2016 |
| 1310-58-3 | Potassium hydroxide | 21 Mar 2016 |
| 101-14-4 | 3,3'-Dichloro-4,4'-diaminodiphenylmethane | |
| 1307-96-6 | Cobalt monooxide | 29 Mar 2016 |
| 1313-99-1 | Nickel monoxide | |
| 1314-13-2 | Zinc oxide | |
| 1314-56-3 | Diphosphorus pentaoxide | |
| 1317-38-0 | Copper monoxide | |
| 12035-72-2 | Trinickel disulfide | |
| 7664-93-9 | Sulfuric acid | |
| 7786-81-4 | Nickel sulfate |
In addition, two PECs that previously finished LR election (elected in the first round) were deleted because the elected LRs of these two PECs have opted out. The two substances are:
| CAS No. | Chemical Name | Date of LR Election |
| 2437-29-8 | Bis[[4-[4- (dimethylamino)benzhydrylidene]cyclohexa-2, 5-dien-1-ylidene]dimethylammonium] oxalate, dioxalate | 6 Jan 2016 |
| 91-20-3 | Naphthalene | 6 Jan 2016 |
The registration deadline for the first batch of 510 PECs is 30 Jun 2018. There are still 341 PECs requiring LR election. Considering the time required during consortium communication, data gap analysis, data purchasing, generating testing data, etc., potential registrants should join the Chemical Substance Information Communicative Organization (CICO, similar to SIEF) and finish LR election as soon as possible.
