“If both forwarders will move the same cargo from China to Istanbul, why should I choose the more expensive one?”
That is one of the most reasonable questions a customer can ask. Side by side, the decision appears simple: one forwarder quotes USD 5,176 and the other USD 4,112. With a USD 1,064 gap, choosing the lower figure initially looks like sound commercial judgment. In air freight, however, comparing only the opening figure can hide the shipment’s true cost.
What was being shipped?
Non-dangerous machine spare parts were to move from a manufacturer in Shanghai to Istanbul.
| Shipment detail | Value |
|---|---|
| Gross weight | 780 kg |
| Total volume | 4.25 m³ |
| Packages | 3 pallets |
| Commodity | Non-dangerous machine spare parts |
| Goods value | Approximately USD 42,000 |
| Origin | Shanghai |
| Destination | Istanbul |
| Cargo-ready day | Wednesday |
Why was the chargeable weight 780 kg?
Under the general rule explained by IATA, volumetric weight is calculated by dividing the shipment’s volume in cubic centimetres by 6,000. The divisor should still be confirmed before booking because carrier- or commodity-specific rules may differ.
The customer had two quotations
Both prices referred to the same cargo, but they did not include the same transport plan or service scope.

Where did the saving disappear?
The first delay began in China
The factory released the cargo on Wednesday, and it reached the consolidation warehouse the next day. To maintain the lower rate, it had to move with other consignments. The Friday consolidation did not close; by Sunday, when the cargo was ready, the planned flight no longer had sufficient space. The shipment moved to the next available flight.
- Freight-rate increase
- 780 × USD 0.35 = USD 273
- Waiting and repeated handling
- USD 190
The connection was missed at the hub
The first flight arrived late, so the cargo missed its onward connection and waited about two days for the next flight. The quoted 5–7-day transit became 12 days. Consolidation and connecting flights are not inherently poor choices; for flexible cargo they can deliver substantial savings. The risk here was dependence on other shipments and unconfirmed capacity.
For production-critical spare parts, an uncertain routing selected only for the lower rate can create a larger commercial loss.Incomplete product details extended the wait in Istanbul
The commercial invoice described the goods only as “metal machine parts”. A more precise commodity description, intended use and technical documents were requested, so corrected information had to come from the manufacturer. With a weekend in between, the cargo remained in the terminal’s temporary-storage area for about six days.

How did USD 4,112 become USD 5,535?
| Cost item | Amount |
|---|---|
| Initial consolidated-service quote | USD 4,112 |
| Freight increase after flight change | USD 273 |
| Waiting and repeated handling in China | USD 190 |
| Storage and related terminal charges in Istanbul | USD 710 |
| Additional document review and handling | USD 100 |
| Urgent-truck premium | USD 150 |
| Total realised logistics cost | USD 5,535 |
The initial nonstop quote was USD 5,176. The option that appeared USD 1,064 cheaper at the start ended up costing USD 359 more than the nonstop alternative.
Customs duties, the standard customs-broker fee and ordinary import costs common to both options were excluded. The comparison covers only costs created by differences in scope, routing, delay and coordination.The hidden cost: late arrival
The cargo contained production spare parts. Because of the delay, the company postponed work and bought more expensive material locally as a temporary solution. The scenario assumes a USD 1,200 business impact.
USD 5,535 logistics cost + USD 1,200 business impact = USD 6,735Had the nonstop movement operated as planned and the import documents been reviewed in detail before departure, the total economic difference between the two decisions could have been approximately USD 1,559. This is a scenario comparison, not a guaranteed outcome.
The real problem was not the low price
The shipment became expensive because two quotes were compared as though they covered the same service. Quote A included confirmed capacity, a shorter routing and detailed pre-departure document review. Quote B was cheaper, but capacity was not firm, departure depended on other cargo, and detailed import-document review was outside scope.
It was also unclear whether “5–7 days” meant factory pickup to Istanbul arrival or only the period after the flight departed. Small ambiguities can create large cost differences in a live operation.
Do not ask only for the price
- 01Is the service nonstop or connecting?
- 02If it connects, which country or airport will be used?
- 03Are the airline booking and weight/volume capacity confirmed?
- 04Does the quoted time run from pickup to arrival?
- 05Until what date is the rate valid?
- 06Which origin, terminal, storage and destination charges are included?
- 07Will the commercial invoice, packing list and commodity description be reviewed before departure?
- 08If the cargo misses the planned flight, how will the rate difference and fallback plan be managed?
If these questions do not receive clear answers, you do not have a complete quotation; you have an opening price.
The cheapest route or the right route?
Not every shipment should move nonstop. Consolidation can be sensible when delivery is flexible, production will not stop and a few days of delay will not create material loss. Customers should not pay unnecessarily high freight.
For production-critical parts, seasonal goods, exhibition material or orders with a promised delivery date, however, comparing only the per-kilogram rate is risky. The right decision is not automatically the most expensive option; it is the routing that best balances cargo value, delivery date, delay risk and conditional costs.
PSP Expres does not aim to recommend the most expensive flight for every shipment. We aim to explain the differences between nonstop, connecting and consolidated options clearly and reduce avoidable surprises after the shipment begins.
What matters is not only how many dollars the cargo costs to fly, but when it can be delivered and at what total cost.
Frequently asked questions about cheap air-freight quotes
Is a cheap air-freight quote always risky?+
No. A clearly scoped consolidation with confirmed capacity can be economical and appropriate when the delivery date is flexible.
Does a nonstop flight eliminate every delay?+
No. It reduces connection risk, but weather, technical, security, slot, terminal and customs factors can still affect timing.
Is volumetric weight always divided by 6,000?+
6,000 is the general rule explained by IATA. The applicable carrier, commodity, packaging or contract rule should still be confirmed.
Can storage and terminal costs be fixed in advance?+
A reliable estimate requires the service provider’s current tariff, free time, AWB structure, cargo details and expected storage period.
What is needed to compare two quotes?+
Provide the packing list, commodity description, dimensions, gross weight, origin, destination, cargo-ready date, required delivery date and each quote’s included and excluded items.
