The Customs Department aims to link the National Single Window (NSW) with three more countries this year, expanding the electronic exchange system of trade-related data.
The additional three countries are Myanmar, Cambodia and the Philippines, said director-general Krisada Chinavicharana.
Cambodia started a trial run for the NSW with Thailand at the beginning of July, he said.
The Customs Department is also developing the NSW electronic exchange system for China and South Korea, aiming to ease trade with these countries.
The NSW is expected to improve Thailand's score in the World Bank's Ease of Doing Business report, Mr Krisada said.
The single window is to help cut Thailand's logistics cost to 12% by 2021 from 13.8% currently, he said.
The volume of trade data submissions through the NSW has increased, from 78.8 million in 2016 to 103 million in 2017 and 123 million in 2018.
For the first five months of this year, 51 million trade data transactions were made through the NSW.
The Customs Department has joined forces with 36 government agencies and state enterprises, 17 commercial banks and 9,900 operators to connect trade data electronically through the NSW to facilitate convenience for exporters, importers and logistics operators in accordance with the Thailand 4.0 policy.
From Oct 1, 2018 to July 4, 2019 the department managed to amass 83.2 billion baht, up 684 million baht from the year-earlier period and exceeding the target by 6.5 billion baht.
The increased revenue could be due to a 20% surge in auto-related tax.
With greater-than-targeted collection, the Customs Department estimates that revenue will be similar to the 108 billion baht received in fiscal 2018, Mr Krisada said.
