Shipping from China to the US Methods

Shipping from China weight calculation.
As with most businesses, cost can’t be the only consideration but it is usually a primary and determining factor.
So let’s first start with how to calculate the shipping from China price. There are two different weight concepts here. One is the actual weight and the other one is the dimensional weight. As shown in this picture here,

Actual Weight is exactly what the product weighs including packaging. Dimensional Weight takes into account the volume, including length, width & height of the package that you are shipping. …
For sea freight:
Dimensional weight = Length (cm) x Width (cm) x Height (cm)/6000.
while for air freight:
Dimensional weight = Length (cm) x Width (cm) x Height (cm)/5000.
 The Billable Weight is defined as the greater of the two weights (actual vs. dimensional) and this will be used to calculate the final shipping rate. 
Because of this rule, you want to communicate with your supplier and try to package your goods in the best way that has the smallest package volume. If you are looking at ongoing shipments, discuss packaging options with your supplier. You might be able to seriously cut the freight costs.
