HOW THE FREIGHT COSTS ARE CALCULATED:
Air shipments have standards to calculate the cost of the shipment.
Real weight and volumetric weight.
The actual weight is the one that we measure on the scale, the volumetric weight is the space the product occupies.
The shipping cost is calculated by the physical space that your order occupies on the plane. The cost of your order depends on a calculation to confirm which of the two measures is the largest!
