Hello guys, I'm moving to Thailand and after donating 80% of my stuff to the thrift store I'm about to hire an international relocation company and ship some belongings of personal value to Thailand. Most of the items are pretty common: books, photos, posters and paintings, clothes, and some dishes with family value. The only odd thing in the shipment would be a used foosball table that is not available in Thailand, I would like to think that having only a few items that needs customs clearing and import duties would be manageable. Does anyone have experience on how to coordinate this with the Thai Customs and which items to avoid in the shipping that may cause a lengthy and costly bureaucratic halt at the customs? Any previous experience or sensible advice would be very appreciated Thanks, Matt
