How Your International Shipping Cost is Calculated

Using comGateway's International Shipping Cost Calculator

Ever wondered how we come up with your shipping cost? It may seem complicated, but it’s actually quite easy! Here are the steps on how comGateway calculates your international shipping cost:

Determine the shipping weight of your package.

To compute for your shipping cost, we need some bits of information about your package. Aside from its delivery destination and its value, we also have to know its shipping weight.

At comGateway, we consider both the volumetric and actual weights of your package. Whichever is greater between the two will be your package’s assigned shipping weight. 

Actual weight versus volumetric weight

So what’s the difference?

Actual weight is the physical weight of your package measured in kilograms (kg), whereas volumetric weight refers to its physical size or the “volume” it occupies – which you derive from its dimensions.

Maybe you’re thinking, “Why not just consider actual weight as your package’s shipping weight?” That seems easier, right?

Well, for international shipping, the physical size of the packages, as well as the space they occupy, matters just as much as how heavy they are. We all know how some goods are placed in too-big boxes, and they take up a lot of space in an aircraft’s cargo.

It is for this reason that volumetric weight, or the physical size of your package, is also considered.

Take a look at the table below for the volumetric and actual weights of some of the US items our customers are buying and shipping internationally:

 How is volumetric weight calculated?

To get your package’s volumetric weight, we first measure its dimensions. The weight is then derived by multiplying the dimensions and dividing the result via a volumetric factor.

Now that your shipping weight is determined, it’s time to get your shipping cost.

How are shipping fees calculated?

As per industry standard, comGateway calculates shipping charges based on a flat fee for the first half-kilogram (0.5 kg), with a lower subsequent fee charge for every succeeding half-kilogram.

If the volumetric weight of your package can be reduced, a Repack option will be available for the package. Selecting Repack will display the weights of your package. And by confirming Repack, you agree to reduce the volumeric weight when your package is arranged for international shipping thereby reducing the shipping cost.

Still feeling lost? Don’t sweat it! We’ve got some tools that will help you determine both your package’s shipping cost and shipping weight. Say hello to our Cost Calculator and Live Estimate tools.
