Some customs jurisdictions have several
offices, which often run independently. It is a problem in countries with more than one
port, such as Indonesia and the Philippines as these countries are archipelagic in
nature, thus being widespread and hence difficult to control. In Indonesia, while the
major ports are coordinated, the small ports lack coordination. The East and West
Malaysian ports also lack coordination in terms of the customs rules. Thailand also has
a large number of private ports which tend to interpret existing regulations differently.
