Thailand has submitted its formal defence document to the United States by the 15 April 2026 deadline, rejecting allegations under Section 301 trade measures relating to excess production capacity and goods linked to forced labour. Deputy Prime Minister Suphajee Suthumpun is also preparing to meet the US Trade Representative (USTR) in early May as discussions intensify over potential tariff actions affecting Thai exports.

The Ministry of Commerce confirmed that Thailand delivered its rebuttal on time in response to the US Trade Representative’s investigation under Section 301. The case covers two main allegations: excess production capacity in automotive and parts, rubber products and electrical appliances, with 16 countries including Thailand named, and concerns over imports of goods linked to forced labour, with 60 countries including Thailand identified. All countries were invited to submit evidence by 15 April 2026.
Thailand’s submission states that it does not have excess production capacity in the three sectors identified. It also argues that government policy, in place since a previous administration, encourages the use of domestic raw materials and components to strengthen local manufacturing, rather than relying on external supply chains. The US has also raised concerns that Thailand could be used as a transit point for rerouted goods to avoid higher tariffs. On forced labour, Thailand stated it does not import goods from countries associated with forced labour.
Deputy Prime Minister Suphajee said she is confident in Thailand’s position but acknowledged uncertainty over the outcome of the US review process. She said, “We are confident in Thailand’s explanation because we are not as accused, but uncertain about the review outcome.” According to the timetable, countries under review may submit further clarifications around 13 May 2026, with Suphajee planning an early May trip to meet the USTR, followed by a possible second visit or video conference in mid-May to present Thailand’s defence directly.
ThaiRath reported that following the mid-May engagement, the USTR is expected to issue a decision within seven days, outlining any measures to be applied, including potential import tariffs. The US aims to complete the process before the 150-day tariff period under Section 122 trade law for trading partners ends around 24 July 2026, during which temporary tariffs of 10-15% apply. Any Section 301 measures could then continue beyond that period without interruption.
