Initial examination revealed that they were ketamine, but another test from 66 sacks of the substances showed that they were trisodium phosphate, resulting in further examination of the other 406 sacks.
ONCB secretary-general Wichai Chaimongkol said that 600 sacks, totalling 16 tonnes, were also found in Taiwan and four substances -- ketamine, Bromo-4 Methylpropiophenone, sodium carbonate and trisodium phosphate -- were found.
Ketamines were intentionally hidden among 600 sacks labelled as trisodium phosphate before sending them to Thailand. The report from Taiwan made officials suspect that the 406 sacks found at the Chachoengsao warehouse might have hidden substances as well.
Jeremy Douglas, UNODC regional representative, said that the international officer would take part in this examination and bring some examples to test at its lab.
The examination will begin on November 24 to ensure transparency, while the ONCB has found no evidence of politicians’ involvement.
