In Satun Province, the Tammalung Port and Customs Port were constructed to serve cargo
vessels up to 400 deadweight tonnage (DWT). Due to limitations on channel depth of less than 4
m and the existing quay length, which is not suitable for accommodating ro–ro ferry vessels, the
Tammalung Port does not have much development potential for IMT-GT trade. The Customs
Port nearby has more potential to serve IMT-GT sub-regional trade. Due to this Satun Province
has allocated a budget of THB43 million for port improvement and expansion.
