Quick decision table
Practical steps
- Confirm ready date and latest acceptable warehouse arrival date.
- Calculate actual weight, volumetric weight, and total CBM.
- Confirm whether destination is FBA, 3PL, commercial warehouse, or multiple addresses.
- Compare air, ocean, or mixed plans by budget and stockout risk.
- Review whether battery, branded, or special cargo can use the selected route.
What can change the answer
- Cargo value and margin
- Inventory safety days
- Whether carton dimensions can be optimized
- US final-mile address and appointment rules
How Qianding can help
- Compare ocean and air routes for the same shipment
- Explain how volumetric weight and CBM affect price
- Check final delivery by US ZIP
- Suggest split plans for urgent and planned cargo
What the customer should prepare
- Provide ready date and target arrival window
- Provide cartons, weight, and dimensions
- Explain stockout or promotion timing
- Confirm acceptable budget
Operational sample
Operational sample: a seller has 20 cartons urgently needed for FBA and 80 cartons that can wait. The urgent 20 cartons can move by air DDP while the larger batch moves by ocean DDP.
FAQ
Is ocean always cheaper than air?
Often for larger cargo, but light bulky goods, small shipments, and destination differences can change the result.
When does air transit time start?
Confirm whether the quote counts from receiving, departure, US arrival, or final receipt.
Can one shipment be split into two modes?
Yes. Splitting by inventory risk and cost target is common.
Quick rule?
Urgent, small, high-value cargo leans air; bulky, heavy, planned replenishment leans ocean, then actual data confirms.
