Amazon Air uses a volumetric factor of 5,000 — lower than the IATA standard of 6,000. This means volumetric weight is proportionally higher relative to size, making it more likely your chargeable weight will be based on volume rather than actual weight. Always confirm the factor with Amazon Air for your specific shipment, as rates can vary by lane and product type.

Amazon Air (QY) uses a volumetric factor of 5,000 to calculate dimensional weight. The formula is:
Volumetric Weight (kg) = (L × W × H in cm) ÷ 5,000
Chargeable Weight = MAX(Actual Gross Weight, Volumetric Weight)As an express carrier, Amazon Air applies a factor of 5,000 — which is lower than the IATA standard of 6,000. This means the volumetric weight will be higher relative to the same shipment dimensions, making it more common for volumetric weight to be the chargeable basis.
Always verify the exact rate basis with Amazon Air or your freight forwarder before booking, as surcharges, fuel levies, and lane-specific tariffs may apply on top of the base chargeable weight rate.
