The Department of Foreign Trade says 2,120 Thai product lines, worth 61.58% of Thai exports to the US (US$56.2bn of US$91.3bn), are exempt from the Section 301 tariff. About 28% of exports still face the 12.5% rate plus MFN, and some of that is already under Section 232. Rice, tuna, shrimp, pet food, sauces and silver or metal jewellery are among the exposed items. Only 48 lines face a 2.5-point disadvantage against rivals, mainly diamonds, jewellery and orchids. If you export to the US, check your HS codes against the exemption list and price exposed lines before quoting. Low-margin exporters in the 48 lines should watch closely.
