Shipping cost can change after packing if carton size, gross weight, route, or delivery terms are different from the estimate. But buyers should be careful when a supplier suddenly raises shipping cost after the goods are ready. At that stage, the buyer has less flexibility and may feel pressured to accept.
The safest response is to compare the original quote with actual packed-goods data and the agreed trade term.
Ask for actual carton data
Request photos of packed cartons, carton count, dimensions, gross weight, CBM, and product quantity per carton. Then ask whether the freight quote is based on actual weight, volumetric weight, or container space.
For FBA carton checks, read our internal guide on wrong carton weight before China pickup. DDPexpert’s freight forwarder from China guide explains how shipping quotes should be compared.
Questions before approving the new cost
- What carton data was used in the first quote?
- What carton data is being used now?
- Did packaging change after sample approval?
- Is the quote EXW, FOB, DAP, or DDP?
- Can another forwarder quote using the same data?
Check whether the supplier caused the increase
If the supplier packed inefficiently, used oversized cartons, or changed packaging without approval, the added cost should be discussed as a supplier responsibility issue, not simply passed to the buyer.
For packaging risk, see the pre-shipment packaging test checklist. DDPexpert’s custom packaging China guide is useful when packaging affects freight cost.
Final recommendation
When shipping cost changes after packing, ask for the data behind the new quote. Compare cartons, weight, CBM, trade terms, and alternative quotes before approving extra payment.
