Global trade relies heavily on shipping by sea from China, which accounts for over 90% of international cargo. Importers choose sea freight because it offers the best balance of cost, reliability, and capacity. However, rising fuel costs, port congestion, and seasonal demand affect prices. This guide explains costs, timelines, documents, methods, and strategies to optimize sea freight shipments, with real-world examples from China to key destinations.
What Is Sea Freight from China?
Sea freight involves transporting goods in containers on cargo vessels. Companies typically book either:
- FCL (Full Container Load): One shipper occupies the whole container.
- LCL (Less than Container Load): Cargo is consolidated with other shipments.
Accordingly, shippers with large volumes save more per unit with FCL, while smaller companies benefit from LCL flexibility.
How Much Does Shipping by Sea from China Cost?
Sea freight is priced based on container size, route, and demand.
| Container Type | Average Price (USD) | Capacity | Best Use Case |
|---|---|---|---|
| 20GP | $2,200 – $2,700 | ~28 CBM, 21–23 tons | Small to medium shipments |
| 40GP | $4,300 – $4,900 | ~58 CBM, 26–28 tons | Furniture, textiles, machinery |
| 40HQ | $4,500 – $5,200 | ~68 CBM, 26–28 tons | Lightweight bulk cargo |
| LCL (per CBM) | $120 – $160 | Charged per volume | Shipments <15 CBM |
Moreover, costs increase by 15–20% during peak seasons such as pre-Christmas and Chinese New Year.
Why Choose Shipping by Sea from China?
- Low Cost: Cheapest mode for bulk cargo.
- High Capacity: Handles oversized goods.
- Global Reach: China connects to 600+ ports.
- Sustainability: Lower carbon footprint than air.
However, transit times are longer compared with air freight.
What Is the Transit Time for Sea Freight from China?
| Destination | Transit Time (Days) | Notes |
|---|---|---|
| China → USA (LA) | 18–25 | West Coast faster than East Coast |
| China → UK (Felixstowe) | 28–33 | Includes Europe’s largest port |
| China → Australia | 20–25 | Stable schedule, high demand lane |
| China → Africa (Lagos) | 35–42 | Congestion may add delays |
| China → SE Asia | 12–20 | Shortest, highly frequent sailings |
In addition, delays can occur due to customs, strikes, or weather disruptions.
What Documents Are Required for Sea Freight?
| Document | Purpose |
|---|---|
| Bill of Lading | Evidence of cargo receipt & shipment |
| Commercial Invoice | Declares value for customs |
| Packing List | Cargo details, dimensions, weight |
| Certificate of Origin | Confirms Chinese origin |
| Insurance Certificate | Covers damage/loss risk |
| Import License | Some countries require for clearance |
Without accurate documents, clearance may be delayed, causing extra charges.
How Does Sea Freight Compare to Air and Rail?
| Aspect | Sea Freight | Air Freight | Rail Freight |
|---|---|---|---|
| Cost | Lowest per CBM | Highest per kg | Medium |
| Speed | 20–35 days | 3–7 days | 12–18 days |
| Capacity | Largest (up to 20,000 TEU) | Limited to aircraft hold | Limited to inland routes |
| Reliability | Port delays possible | Weather/fuel costs vary | Border delays possible |
| Best Use Case | Furniture, textiles, bulk | Urgent, electronics | Europe-bound cargo |
To summarize, sea freight is best for large and non-urgent shipments.
