What are the customs tax rules for shipping personal items to Thailand, especially clothing and household goods?

When shipping used clothing and personal items to Thailand, customs tax can apply even for items with a low declared value. Many users report varying experiences, indicating that while some packages may go through without issue, others can incur significant customs fees. Generally, personal belongings sent via post have a better chance of being tax-exempt if declared below a certain value (often around $50). It is suggested to transport items in luggage when possible and to be aware of regulations that allow one duty-free container of household items if relocating to Thailand under specific circumstances.
