The ASEAN Trade in Goods Agreement (ATIGA) aims to achieve free flow of goods in the region resulting to less trade barriers and deeper economic linkages among Member States, lower business costs, increased trade, and a larger market and economies of scale for businesses. Through ATIGA, Brunei, Indonesia, Malaysia, Philippines, Singapore, and Thailand have eliminated intra-ASEAN import duties on 99.65 percent of their tariff lines. Cambodia, Lao PDR, Myanmar, and Viet Nam have reduced their import duties to 0-5 percent on 98.86 percent of their tariff lines. Today, focus is given to addressing non-tariff measures that could have non-tariff barrier effects on the region’s trade and business activities. Timor-Leste will be required to meet these provisions as they continue on their journey to ASEAN accession.
