Thai Customs Mae Sot Border Checkpoint
Thai Customs Mae Sot is the principal Thai Customs Department enforcement and clearance point at the Moei River border crossing connecting Mae Sot (Tak Province, Thailand) with Myawaddy (Kayin State, Myanmar). Processes formal bilateral trade flows on the Second Thai-Myanmar Friendship Bridge, including Thai industrial goods, garments, agricultural inputs, consumer goods, and Myanmar natural-resource exports. The checkpoint is critical to the Thailand-Myanmar border-trade corridor valued at THB 80-120B annually. Operations are affected by political instability in Myanmar, border-crossing hour restrictions, and informal cross-border activity on the Moei River. Coordinates with Mae Sot Industrial Estate operators on export-processing-zone documentation.

Checkpoint operations and trade flows
Formal trade
Second Thai-Myanmar Friendship Bridge clearance
The Second Friendship Bridge (opened 2006) handles formal bilateral trade under Thai Customs Department supervision. Processed formal trade value: $2.32–120B annually. Thai exports dominate: consumer goods, industrial inputs, garments, and construction materials.
Myanmar imports
Natural resources and agricultural products
Myanmar exports to Thailand through Mae Sot include teak and hardwoods (prior to international restrictions), minerals, jade, gems, agricultural produce, and garment assembly. Myanmar import values are considerably smaller than Thai export flows.
Special Economic Zone
Mae Sot Special Economic Zone coordination
Mae Sot is one of Thailand's 10 designated Special Economic Zones. The customs checkpoint coordinates with BOI-promoted Mae Sot Industrial Estate on EPZ (Export Processing Zone) documentation, bonded warehouse operations, and re-export procedures.
Informal trade
Moei River informal cross-border flows
Significant informal trade moves across the Moei River via longtail boats and shallow-water crossings outside formal checkpoint hours. Thai authorities periodically conduct enforcement operations; informal volumes are estimated to equal 20–40% of formal flows.

Watchpoints 2025–2026
Myanmar conflict
Civil war impact on border trade
Myanmar civil conflict since February 2021 has intermittently disrupted road transport from Myawaddy to Yangon. Kayin State fighting near the bridge has caused periodic closures and rerouting. Thai Customs volumes directly reflect these disruptions.
SEZ investment
Mae Sot SEZ factory development
Mae Sot Industrial Estate occupancy and new BOI-promoted manufacturing investment depends partly on Myanmar political stability. A stabilisation scenario would accelerate garment and light-manufacturing migration from Myanmar to the Thai-side SEZ.
Informal trade formalisation
Customs modernisation programme
Thailand Customs Department is implementing the National Single Window and e-Customs systems. Mae Sot digitisation would capture more informal flows in formal statistics and improve revenue collection.
