How to Ship Cargo by Sea: Step-by-Step

Shipping cargo by sea remains the most cost-effective method for transporting goods from China to North America, Europe, or other global destinations. However, without proper knowledge of the process, importers may face delays, unexpected fees, or customs issues. This guide breaks down the step-by-step process of sea freight, offering practical advice for smooth, predictable shipments.

1. Step 1: Determine Your Shipping Requirements

Before booking, define:

• Cargo type and volume: FCL (Full Container Load) vs LCL (Less than Container Load)

• Destination port: e.g., Los Angeles, Vancouver, Montreal

• Transit time requirements: standard vs expedited

• Special handling needs: fragile, oversized, refrigerated cargo

💡 Tip: Understanding these requirements upfront allows you to choose the most suitable shipping method and avoid unnecessary costs.

2. Step 2: Select a Freight Forwarder or Carrier

• Freight forwarders manage end-to-end logistics: booking, customs clearance, documentation, consolidation, and inland delivery.

• Direct ocean freight carriers provide vessel transport only, ideal for experienced importers shipping FCL regularly.

3. Step 3: Prepare Cargo and Documentation

a) Cargo Preparation

• Proper packaging and palletizing to prevent damage

• Mark cartons with shipping marks, weight, and consignee details

• Segregate fragile, hazardous, or perishable items for special handling

b) Documentation

Essential documents include:

• Commercial Invoice: details product, quantity, and value

• Packing List: outlines carton contents and dimensions

• Bill of Lading (B/L): proof of shipment issued by carrier

• Customs Forms: HS codes, Importer ID, ISF/AMS (for USA)

💡 Tip: Accurate documentation avoids customs delays, fines, or shipment rejection.

4. Step 4: Booking and Container Allocation

• Book FCL or LCL space with a carrier or forwarder

• Confirm container availability and schedule

• Forwarder may consolidate LCL shipments to optimize costs

💡 Insight: Peak seasons (August–October) can lead to space shortages and higher rates. Early booking is critical.

5. Step 5: Export Customs Clearance in China

• Freight forwarder submits export declaration to Chinese authorities

• CBP-like inspection for compliance with regulations

• Carrier receives approval to load cargo onto the vessel

Pro Tip: Using a licensed forwarder ensures smooth customs processing and correct paperwork.

6. Step 6: Ocean Transit

• Container is shipped according to agreed schedule and route

• LCL shipments are consolidated and may have slightly longer transit times than FCL

• Regular updates from forwarder or carrier track cargo location

Example: Shanghai → Los Angeles transit typically 18–25 days, depending on carrier and route.

7. Step 7: Import Customs Clearance

• Forwarder or customs broker submits documentation to destination customs

• Duties and taxes are calculated based on HS code, CIF value, and country regulations

• Inspection may be required for certain cargo

💡 Tip: Properly prepared documentation and accurate HS codes reduce the risk of delays or penalties.

8. Step 8: Inland Delivery / Final Destination

• After clearance, cargo is delivered to:

  • Warehouse

  • Amazon FBA center

  • Customer location (door-to-door service)

  
  

• Freight forwarder coordinates trucking, rail, or other inland transport as needed

Example: WAYTRON LOGISTICS LIMITED offers door-to-door solutions, managing both sea freight and inland delivery seamlessly.

9. Step 9: Risk Management

• Cargo insurance protects against loss, damage, or delay

• Packaging strategies reduce exposure to moisture, rust, or breakage

• Forwarders advise on peak season planning, consolidation, and routing to minimize risk

Shipping cargo by sea involves careful planning, documentation, and coordination from origin to destination. Choosing the right shipping method, preparing cargo properly, and working with a professional freight forwarder ensures timely, cost-effective, and reliable delivery.
