Please leave comments with the order if either one of them is not suitable for shipping to your country and for customs declaration.

Shipping Cost

The shipping cost mostly depends on the shipment gross weight and shipping destination.

For shipment under 21kgs (kilograms), the shipping cost calculation bases on 0.5kgs. The formula is: X+(Y-0.5)/0.5*Z.
X=1st 0.5kgs cost
Y=shipment gross weight (Kilogram)
Z=shipping rate on each additional 0.5kgs
For example
To USA, the initial 0.5kgs cost is usually around US$20, and the additional cost is US$3.5 per 0.5kgs.
For 15kgs to USA, the shipping cost is: 20+(15-0.5)/0.5*3.5=US$121.5

For shipment above 21kgs, the shipping cost calculation bases on 1kgs. The formula is: Y*Z.
Y=shipment gross weight (Kilogram)
Z=shipping rate each Kilogram
For example
To UK, the shipping rate is 6.5USD/KGS.
For 22kgs to UK, the shipping cost is: 22*6.5=US$143

Generally, the larger the shipment gross weight the lower shipping cost for each item of products.
