Just glancing through this and to be honest, I have no idea which US products are imported into Thailand and are therefore subject to high tariffs. However, I suspect that as with other countries, its more about what countries DONT export to Thailand BECAUSE of the high tariiffs.
For example, a fair proportion of Japanese branded pick up trucks that are actually assembled in Thailand are exported to the UK. There are very few UK/European assembled vehicles exported to Thailand and that is most likely due to the protectionist tariffs the country imposes on them. BMW used to produce some 3 series models in Chonburi - not sure if they still do but that's a rarity.
Not really sure what the answer is to be honest. Thailand seems to have been very successful in getting Japanese manufacturers to build assembly plants in the country but do any of those exports end up in the US? I suspect most are sold in the domestic/ASEAN market. Would they reduce tariffs on vehicles and risk what they have?
If US auto makers are anything like others - a lot of parts might be made in Thailand and shipped to the US, along with parts made in other countries and then assembled in the US.
The auto industry is one matter that Trump doesn't seem to know much about - its a global business with parts made all over the world. His tariff war must be creating a real headache for both the industry as a whole and US auto makers in particular.
