How is dimensional weight calculated?

Dimensional weight is calculated as length x width x height divided by the carrier's dimensional factor (typically 5000 for international or 3000 for domestic). The system uses whichever is greater — actual or dimensional weight — to determine the billable weight.

Which carriers are included in the comparison?

Major carriers including national postal services and leading private couriers in the selected region are included. The carrier list varies by destination country for international shipments.

Are the displayed rates guaranteed?

Rates shown are based on publicly available carrier tariffs and are for comparison purposes only. They are not a binding quote. Always confirm the final rate with the carrier directly before dispatching a shipment. This tool does not replace official carrier pricing.

Does the tool account for customs duties on international shipments?

Shipping costs are calculated for international routes but customs duties and import taxes are not included, as they vary by destination country, product category, and declared value.

How do I use the bulk calculation feature?

Prepare a CSV or Excel file with columns for weight and dimensions for each shipment. Upload the file and the tool generates a per-row and total cost breakdown across all carriers.

Can I compare rates if I have a negotiated contract with a carrier?

The tool uses standard published tariffs. If you have a volume discount agreement, your actual rates may differ. Use the comparison as a market benchmark and apply your contracted rate separately.
