The choice between sea, rail and air starts with four facts: deadline, weight, volume and cargo value. Pickup in China, final delivery in Poland and the cost of a possible shortage also matter. A headline freight rate is not comparable until origin charges, customs and last-mile delivery are included.
At-a-glance comparison
| Mode | Indicative time | Best use | Main advantage |
|---|---|---|---|
| Sea freight | 35–45 days | Large consignments, FCL and LCL, planned replenishment | Lowest unit cost at larger volumes |
| Rail freight | 18–25 days | Pallets and medium- or high-value goods | A balance between time and cost |
| Air freight | 3–7 days door-to-door | Samples, urgent parts, light and valuable goods | Fastest delivery and stock recovery |
Note: lead times are indicative. Pickup location, terminal or port, capacity, season, customs and domestic delivery all affect the final schedule.
When should you choose sea freight?
Sea is the natural option for FCL containers, heavy products and regular shipments that can be planned in advance. LCL makes smaller consignments possible without booking a full container, although local and handling charges represent a larger share of the cost.
When does rail have an advantage?
Rail is useful when 35–45 days by sea is too slow and air exceeds the budget. It suits palletised cargo, components and goods whose absence could interrupt production or sales. CargoNet runs rail consolidation to Warsaw, including shipments from one pallet.
When is air freight worth the price?
Air works for urgent, light and valuable shipments: samples, electronics, spare parts and the first batch before a launch. A high freight rate may be economical if it prevents downtime, contractual penalties or lost orders.
Compare more than the freight rate
Total landed cost
Freight, origin and destination charges, customs, duty, tax, insurance and delivery to the warehouse.
Cost of time
Working capital tied up in goods, stockout risk and the cost of delayed production or sales.
Cargo risk
Sensitivity to moisture, temperature and handling, plus batteries, dimensions and documentation.
A mixed strategy often works best
You do not have to choose one mode for the entire order. An urgent portion can go by air or rail and base stock by sea. For regular imports, overlapping orders can maintain availability without creating excessive inventory.
What do we need to compare options?
- pickup in China and final delivery address,
- carton or pallet count, dimensions and gross weight,
- product type, HS/CN code and any batteries or dangerous goods,
- cargo-ready date and latest acceptable delivery date,
- Incoterms agreed with the supplier.
Frequently asked questions
What is the cheapest way to ship from China?
Usually sea for larger consignments, but a correct comparison covers the total landed cost.
How long does freight from China to Poland take?
As a guide: sea 35–45 days, rail 18–25 days and air 3–7 days door-to-door.
When should I choose rail instead of sea?
When the sea lead time is too long and air is disproportionately expensive for the value or margin of the goods.
Can an order be split?
Yes. Move the urgent portion faster and the remaining volume economically by sea.
