We spoke and thanks for the update.
According to the price of USD2150/mt, our cost after clearance is THB73.50/kg (based on exchange rate of USD1.00 : THB33.50).
As of now, we can probably sell to the customers between THB78 to THB80/kg. Assuming a profit margin of THB5/kg, a 20mt shipment (which we can sell in 1 month) can bring us THB100,000 profit. So for now, we need to calculate what our operating cost will be at this initial stage and see if we can at least cover our costs.
Meantime, please advise what are the samples you require from China.
