There are three ways to deliver the goods as following :
The first one is Express ,such as DHL, UPS, TNT and Fedex . It is most convenient because of door to door. This method is suitable to a few goods such as less than 20KG.
Another is air parcel, you should go to airport to take the goods youselves. The charge is cheaper than express, but you should pay the charges of Customs clearance and we should pay the charges of clearance of goods, these charges are fixed no matter what weight or volume it is. This method is suitable to the goods which are more than 100KG.
The rest one is ocean shipping, it is rather cheap, and it will take about 15-30 days to the port if you are in the North America or the Europe.
In general, we deliver the samples by Express, such as DHL, UPS, TNT and Fedex, and ship the goods of order by ocean shipping.
