01Define the packed shipment
Record carton count, dimensions, gross weight, product, value, batteries, liquids, magnets or other classification-relevant facts and readiness date. Quotes based on estimated retail dimensions can change when final cartons and packing method are known.
02Normalize route and responsibility
Use the same pickup address, departure point, destination, customs responsibility, delivery point and Incoterm with named place. Compare door-to-door with door-to-door, or list the missing legs. Port-to-port and airport-to-airport prices do not represent the full buyer cost.
03Check the chargeable basis
Air carriers may use actual or volumetric weight, whichever drives the applicable charge, while courier and ocean services can use their own minimums, volume units and rating rules. Ask the forwarder to show dimensions, divisor or conversion, rounding and billable quantity.
04Break out every charge
Separate pickup, export handling, documents, security or screening, main carriage, fuel or peak surcharge, terminal, destination handling, customs brokerage, duty and tax advance, storage, examination, delivery and insurance. Mark estimates, exclusions and pass-through charges.
05Use a realistic time range
Record cargo-ready date, booking or space lead time, origin handling, scheduled transit, transshipment, destination availability, customs and delivery. Add a range and cutoff assumptions instead of one best-case number. Identify the inventory date the business actually needs.
06Add business consequences
Estimate stockout contribution lost, launch delay, cash tied in inventory, markdown exposure, insurance, damage and the ability to replenish. These are buyer assumptions, not freight charges, but they explain why a faster mode may be rational for a small urgent quantity.
07Check mode eligibility and split options
Have qualified carriers review dangerous-goods status, batteries, liquids, package, documents and destination acceptance for the exact cargo. If both modes are eligible, compare a small air quantity to protect sales with the balance by sea, including two sets of handling charges.
