Best practices for shipments

The maximum allowed dimensions for a package to be shipped are:

• Each side must have a maximum of 150 cm.
• The total dimension limit must not exceed 330 cm.
  • Total dimension = 2 x height + 2 x width + length.
  • The length must be the side with the largest measurement.
    

• The maximum weight is 30 kg (actual or volumetric) considering that volumetric weight = (height x width x length) / 5000.

When a package contains more than one item, its size must be calculated considering the sum of the dimensions of all items, always ensuring that the maximum allowed dimensions are not exceeded.

This value must be informed in the dimensions parameter of the shipments object and will be used to define the shipping cost.

Record the length, width and height of each item and add +1 cm per side as a margin for protection or packaging material. Name these adjusted measurements as L' (adjusted length), W' (adjusted width) and H' (adjusted height).

Also note the individual weight of each item.

Test how items should be stored in the box and select the option that generates the smallest total volume (the most efficient).

• Aligned by length:
  • Length = sum of L',
  • Width = maximum value of W',
  • Height = maximum value of H'.
    

• Aligned by width:
  • Length = maximum value of L',
  • Width = sum of W',
  • Height = maximum value of H'.
    

• Stacked by height:
  • Length = maximum value of L',
  • Width = maximum value of W',
  • Height = sum of H'.
    

Add +1 cm per side again to account for the thickness of the box material and clearance space. You will get the external dimensions: L_ext, W_ext and H_ext.

• Actual weight (kg): sum of the weights of all items + estimated box weight (approx. 0.2–0.7 kg depending on size).

• Volumetric weight (kg): (height x width x length) / 5000

To calculate the shipping cost, you must consider the billable weight, which is the greater of the actual weight and the volumetric weight.
