Measure first
Weight and parcel dimensions can materially change the service options that appear later.
Shipment planning
Plan shipping after the product details are clear.
Compare the actual and volumetric weight, service options at checkout and the requirements for the final destination.
Check destination rules
Import, prohibited-item and consumer requirements vary by country and may change.
Compare shown options
Use the service details available at checkout for the actual order instead of relying on general claims.
