What is Sea Freight? A Complete Guide for Indian Importers & E-commerce Sellers
What is Sea Freight?
Sea freight (also referred to as ocean freight) is the method of transporting goods internationally via large cargo vessels. It remains the backbone of global trade, accounting for over 80% of the world's international shipments by volume.
For Indian importers and e-commerce sellers, especially those sourcing from China, Vietnam, or Southeast Asia, sea freight is the most cost-efficient and scalable option.
Container Types
Full Container Load (FCL): The entire container is reserved for your goods, regardless of whether it is fully utilized. FCL is best suited for bulk orders, fragile items, or shipments requiring added security and less handling.
Less than Container Load (LCL): Your cargo shares space in a container with shipments from other businesses. It's ideal for smaller volumes, early-stage inventory testing, or startups managing tight budgets.
Why Sea Freight Over Air? Air freight is faster, but it comes at a significantly higher per-kilogram cost. Sea freight offers better economies of scale, particularly for Indian e-commerce brands managing large and repeat shipments.
How the Sea Freight Process Works
Step 1: Coordination with Your Supplier
The process begins at the factory. Once your order is ready, the supplier must notify you (or your freight forwarder) with a confirmed cargo-ready date.
Step 2: Booking a Freight Forwarder or Shipping Line
A freight forwarder handles:
- Carrier selection and rate negotiation
- Port operations and export documentation
- Consolidation for LCL shipments
- Coordination with customs agents in both countries
Step 3: Packing and Container Stuffing
Goods are moved to:
- A factory location (common for FCL)
- A consolidation warehouse (for LCL shipments)
Export-grade packing, pallets, and moisture-resistant wrapping are strongly recommended.
Step 4: Export Customs Clearance in China
Key steps:
- Filing the export declaration
- Submitting the commercial invoice, packing list, and contract
- Getting container approval and sealing
Step 5: Ocean Transit
Typical transit times:
- Shanghai → Nhava Sheva: 20–25 days
- Shenzhen → Mundra: 15–20 days
- Guangzhou → Chennai: 18–28 days
Containers are tracked using a Bill of Lading (BL) number.
Step 6: Arrival at Indian Port
Container is unloaded and transferred to a Container Freight Station (CFS) or Inland Container Depot (ICD).
Step 7: Indian Customs Clearance
Indian customs authorities will:
- Inspect your documents
- Validate your HS code classification
- Check for undervaluation or restricted items
- Calculate applicable duties and taxes
Step 8: Inland Transport to Your Final Destination
Delivery to:
- Your company's warehouse
- A third-party logistics (3PL) center
- Amazon FBA or Flipkart fulfillment center

Understanding Sea Freight Costs

Cost Estimates
LCL Shipment (5 CBM from Guangzhou to Mumbai): Freight + handling + customs + duties + delivery = Variable based on product category
FCL Shipment:
- 20-foot container: ₹1.2 – ₹1.5 lakh (excluding duty)
- 40-foot container: ₹1.8 – ₹2.2 lakh
FCL becomes cost-efficient when shipment exceeds 15–18 CBM.
