If your company outside Thailand buys goods from a Thai supplier and you have someone in the country (your agent, employee or supplier) deliver it to your Thai customer, you are considered doing business in Thailand, which according to the Foreign Business Law, your company needs to apply for a Foreign Business License in order to operate as such legally. The business activity is considered retail or wholesale of goods in Thailand, which are in List three of the Foreign Business Law.
However, if you pay the Thai supplier from your country and have it delivered to your country before you send it back into Thailand to your Thai customer, then it is considered an international trade and you do not need to get a Foreign Business License before you can operate such business.
