The company has provided service maintenance locally for the client in overseas, for the material that was imported to Thailand and then after the maintenance is completed , the company will export it back to overseas. How about the VAT for this case?

Panwa : Please note that in case the maintenance service was done locally and the material was  sent back to overseas, it has  VAT 0%.
