Trade Barriers
Last published date:

Thailand is not a signatory to the WTO Agreement on Government Procurement.  High tariffs in certain sectors also remain an impediment to market access.  Non-tariff barriers to trade, such as licensing, labeling requirements, and localization barriers impede commerce.  Price controls and excise taxes, based on an exceedingly complex tax structure, also negatively affect international trade.
Sanitary and phytosanitary (SPS) measures continue to be a source of concern for the United States.  SPS standards for certain agricultural products are applied arbitrarily and without prior notification.
For detailed information on trade barriers, please consult the 2023 National Trade Estimate Report, available from the Office of the United States Trade Representative.
