Establishment and Operations of Free Zones Under Sections 136 and 137
Section 136 of the Customs Act B.E. 2560 empowers the Director-General of Customs to authorize the establishment of Free Zones for industrial or commercial purposes beneficial to the national economy. Zone creators and operators licensed under Section 137 must pay annual fees and comply with all customs control measures, including integrating automated inventory systems linked to the customs mainframe.
Section 140 and Duty Exemption Privileges
Pursuant to Section 140, goods admitted into a Free Zone receive import duty exemption if they are: (1) imported to be used for industrial or commercial manufacturing, or (2) foreign goods entering the zone to be re-exported overseas. Furthermore, domestic raw materials sent into the zone qualify for export duty exemptions or a 0% VAT rate. However, releasing these goods for domestic consumption terminates the exemption, and duties are assessed based on the goods' state on the date of domestic distribution.

High tax privileges demand strict regulatory oversight. Free Zone operators must maintain meticulous stock cards matching physical inventory with customs electronic records. Under customs audit procedures, if any goods are unaccounted for or lack approved production formulas, it is legally presumed that the missing cargo has been illegally distributed into the domestic market, risking heavy duty evasion penalties.
