Sea Freight Shipping Times: How Long Does It Take by Route?
Planning Starts with Knowing the Timeline
Sea freight is the most cost-effective way to move goods internationally, but it's slow. Knowing exactly how long your shipment will take — from factory to warehouse — lets you plan orders, manage working capital, and avoid the expensive mistake of air-freighting emergency stock.

But Transit Time ≠ Total Lead Time
The shipping time above is just the ocean transit. Your total lead time — from placing an order to having stock in your warehouse — includes several additional stages:
| Stage | Typical Duration |
|---|---|
| Production | 15–45 days |
| Pre-shipment inspection | 1–3 days |
| Inland transport to port | 1–3 days |
| Port handling and loading | 2–5 days |
| Ocean transit | 13–38 days |
| Port clearance at destination | 2–7 days |
| Customs clearance | 1–5 days |
| Inland delivery to warehouse | 1–3 days |
| Total lead time | 36–109 days |
For a typical sea freight import from China to the UK, expect 8–14 weeks from order to warehouse. Track every stage in LandedCost.io's shipment management.

Factors That Affect Transit Times
Seasonal Congestion
Port congestion spikes before Chinese New Year (January–February) and during pre-Christmas peak season (August–October). Add 5–10 days during these periods.
Route Disruptions
Canal closures, weather events, or geopolitical issues can force ships to take longer routes. The Suez Canal route saves 7–10 days compared to routing around the Cape of Good Hope.
Transhipment
Direct services are faster but not available on all routes. If your container is transhipped (transferred between vessels at a hub port), add 3–7 days.
Port of Origin
Major ports like Shanghai and Shenzhen have more frequent sailings. Smaller ports may only have weekly or fortnightly departures.
How to Plan Around Shipping Times
- Order early — place orders at least 3 months before you need stock (longer for Chinese New Year)
- Track your shipments — use shipment tracking to monitor every stage
- Build buffer stock — keep 4–6 weeks of safety stock to cover delays
- Consider split shipments — send a small quantity by air and the bulk by sea
- Use a freight forwarder — they know which routes and carriers are most reliable
Quick Comparison: Sea vs Air
| Factor | Sea Freight | Air Freight |
|---|---|---|
| Transit time | 2–6 weeks | 3–7 days |
| Cost per kg | $0.10–0.50 | $3–12 |
| Best for | Heavy, bulky, low-margin | Light, high-value, urgent |
| Minimum viable | 1 CBM (LCL) | 1 kg |
For most importers, sea freight is the default. Air freight is the exception for urgent restocks or high-margin, lightweight products. Model both options using the import profitability calculator.
