In terms of technical barriers to trade, Thailand is an active participant in standard international and regional organizations such as the International Standards Organization, the Pacific Area Standards Congress and the ASEAN Advisory Committee on Standards and Quality. While Thailand has concluded several multi-lateral mutual recognition agreements, the ASEAN Convention on Trade in Goods, concluded by ASEAN countries, requires members to apply technical rules to facilitate the implementation of all ASEAN sectoral recognition agreements (World Bank 2011). In addition, health and plant health issues, as a major exporter of agricultural and fisheries products, are of paramount importance to Thailand. It generally complies with the standards of the World Organization for Animal Health (OIE), Codex Alimentarius and the International Convention for the Protection of Plants. However, it has also been reported that animal health standards are sometimes stricter than those set by the OIE. (WTO 2011). In addition to these rules, exporters must be able to accurately specify their product billings and understand their trade flows. This was a difficult undertaking for Thai companies, as experienced when they were modified the new version (2012) of Thailand`s HS code. Thai Customs asked the exporter (and importer) to indicate the classification of the goods under the new version, which was sometimes different from the previous version.

During this period and according to the rules, country of origin (C/O) forms still required the old version of the HS code (2007), which had different references in the customs declaration. The obligation for Thai companies was to meet the requirements of a 2012 tariff change with outdated documentation of 5 years. As the process was difficult, some exporters did not wait for the C/O to be issued on time and skipped the process. Thailand has signed 12 agreements (6 bilateral and 6 multilateral agreements) with 9 free trade agreements under negotiation or in the process of being implemented. These agreements could have a huge impact on Thailand`s trade and investment in the years to come. In the International Trade and Investment Rankings, Thailand ranks 49th (out of 189 economies) in the World Bank`s Ease of Doing Business Chart 2016. According to the ranking, and compared to the previous year, almost all difficulties have increased, including Thailand`s trade on cross-border groups (55 last year and 56 this year). For example, in the past, supply chains have identified barriers that generally lead to trade facilitation for physical infrastructure, as well as administrative barriers and delays in Thailand`s customs and export processes.
