Why businesses prefer sea freight

• Lower cost compared to air freight

📦 Types of Sea Freight

There are two primary shipping options.

FCL (Full Container Load)

You book an entire container for your cargo.

Best for:

• Large shipments
• Higher security
• Faster handling

Common container sizes:

• 20-foot container
• 40-foot container
• 40-foot high cube container

---

LCL (Less than Container Load)

Your goods share a container with cargo from other importers.

Best for:

• Businesses testing products
• Lower upfront shipping costs

Note:

LCL often involves additional consolidation and deconsolidation charges.

🔄 Sea Freight Process: Step by Step

Step 1: Product Sourcing and Order Confirmation

The process begins when you finalize your supplier in China and confirm your purchase order.

At this stage:

• Product specifications are approved
• Quantity is confirmed
• Payment terms are agreed
• Production begins

Many importers source suppliers through Alibaba.

---

Step 2: Production and Quality Inspection

The supplier manufactures and prepares your goods.

Before shipment, many importers arrange:

• Pre-shipment inspections
• Quantity verification
• Packaging checks

This helps reduce the risk of receiving defective goods.

---

Step 3: Choose a Freight Forwarder

A freight forwarder coordinates the entire shipping process.

Companies like ChinaToBharat can assist with:

• Pickup from suppliers
• Export customs in China
• Sea freight booking
• Customs clearance in India
• Final delivery

---

Step 4: Booking Cargo Space

The freight forwarder books cargo space with a shipping line.

This includes:

• Selecting FCL or LCL
• Choosing vessel schedules
• Confirming departure and arrival ports

Early booking helps avoid delays during peak seasons.

---

Step 5: Pickup from Supplier

The cargo is collected from the supplier’s warehouse and transported to the port.

For LCL shipments, the cargo is moved to a consolidation warehouse where it is combined with other shipments.

---

Step 6: Export Customs Clearance in China

Before goods can leave China, they must be cleared for export.

Documents commonly used:

• Commercial Invoice
• Packing List
• Export Declaration

Once approved, the cargo is released for loading.

---

Step 7: Container Loading and Sealing

The cargo is loaded into a shipping container and sealed.

Important considerations:

• Proper stacking
• Moisture protection
• Secure packaging

For FCL, your cargo occupies the entire container. For LCL, it shares space with other shipments.

---

Step 8: Ocean Transit

The container is loaded onto a vessel and shipped to India.

Typical transit times:

• South China to Mumbai: 18–25 days
• East China to Mumbai: 20–30 days

Transit time may vary due to weather, port congestion, and shipping schedules.

Step 9: Shipment Tracking

During transit, you can monitor your shipment using:

• Bill of Lading number
• Shipping line tracking portals

Freight forwarders also provide status updates.

Step 10: Arrival at Indian Port

The vessel arrives at a port such as:

• Jawaharlal Nehru Port
• Mundra Port
• Chennai Port

The container is unloaded and transferred to the port terminal.

---

Step 11: Import Customs Clearance in India

All imported cargo is processed by the Central Board of Indirect Taxes and Customs.

The process includes:

• Filing Bill of Entry
• Document verification
• Duty and GST assessment
• Inspection if required
• Clearance approval

Required documents usually include:

• Commercial Invoice
• Packing List
• Bill of Lading
• Importer IEC
• GST details

---

Step 12: Duty and Tax Payment

Import duties and IGST must be paid before the shipment is released.

The amount depends on:

• Product HS code
• Customs valuation
• Applicable duty rates

---

Step 13: Container Release and Deconsolidation

After customs clearance:

• FCL containers are released to the importer
• LCL shipments are separated and prepared for pickup

---

Step 14: Inland Transportation

The goods are transported from the port to your warehouse or business location.

Delivery can be arranged by truck or rail depending on destination.

---

Step 15: Final Delivery

The shipment is delivered to your warehouse, store, or fulfillment center.

This completes the sea freight process.
