For international customers, if you have been using some courier service such as DHL, UPS, please advise your account number and we can arrange a pick-up by your courier at your cost. If you do not have such accounts, you will need to pay us relevant shipping cost in advance before we sending out the sample package. Shipping cost will depend on the parcel weight and destination. Contact us and our sales staff will tell you how much the shipping cost will be. For domestic customers, no courier account number will be needed. Just pay the freight when parcel arrived.
