What are the regulations for importing used household goods to Thailand with a non-O retirement visa?

When moving to Thailand with a non-O retirement visa, many expats advise against bringing large quantities of used household items. Comments suggest that it may be more cost-effective to sell belongings and repurchase similar items in Thailand, citing the availability of everything from clothes to electronics. For those considering shipping items, there are regulations that allow for duty-free importation of household goods, but this may require careful consideration of the ownership and residency status of the sender. Overall, the consensus leans towards minimal luggage, typically just two large checked bags and a carry-on.
