Adding up the list of Thai concessions

Negotiations with the US that concluded with a 19% tariff on Thai exports were broadly focused on trade concessions. What did Thailand offer to secure the 19% rate?

- 

The US reciprocal tariff rate on Thai exports dropped from a threat of 36%, effective starting on Thursday, in exchange for several significant Thai concessions.

Thailand proposed eliminating import duties for more than 10,000 items imported from the US (out of roughly 11,000 items in total), mostly consisting of goods that are not produced domestically or are insufficiently produced, such as medical instruments, advanced auto parts, and specialised food products.
