Shipping by sea for small quantity is also very expensive as you need to pay import duty,handle cost,document cost etc,the total cost will be equivalent to the air shipping while its more complicated and wasting time as well.The air shipping cost per kg is approximately between 8USD and 10USD varying from different countries.
