After checking with Customs Officers Sugar Import Tariffs to Thailand from AEC member is 0%, from Korea 7.22% for white sugar and 0% for raw sugar, and from Australia (TAFTA) 21.70% in-quota and 84.60% out-quota.
However, importation of sugar must to approved by OCSB and in their exactly practice only Australia are the same Customs informed but others still use WTO agreement that is tariff 65% in-quota of 13,760mt/year and 94% for out-quota because they are in considering about identification of imported condition first. Will see if there are any news more.
