Sea freight from China is the backbone of global trade. From electronics and machinery to furniture, textiles, and consumer goods, the majority of products made in China travel across oceans before reaching international markets. Yet for many importers—especially first-time buyers or growing businesses—the sea freight process can feel complex and overwhelming.
This comprehensive guide explains sea freight from China in clear, practical terms. We’ll cover container types, major Chinese ports, step-by-step shipping processes, costs, transit times, and common challenges. Most importantly, we’ll explain how working with a professional freight forwarder like CNXtrans can simplify sea freight shipping from China, reduce risk, and save money.
Whether you are importing full containers regularly or shipping smaller consolidated loads, this article will give you a solid foundation for making smarter logistics decisions.
What Is Sea Freight from China?
Sea freight (also known as ocean freight) refers to the transportation of goods by cargo ships across international waters. China, as the world’s largest manufacturing hub and exporter, relies heavily on sea freight to move goods to markets in Europe, North America, Asia, Africa, and beyond.
Sea freight from China is popular because it offers:
Cost efficiency for large or heavy shipments
High capacity for bulk and oversized cargo
Global reach to almost every major port in the world
Flexible shipping options, including full containers and consolidated shipments
Compared to air freight, sea freight is slower but significantly more affordable, making it the preferred choice for most commercial imports from China.
Types of Sea Freight Shipments from China
Before diving into containers and ports, it’s important to understand the two main types of sea freight shipments from China.
FCL (Full Container Load)
FCL means one shipper uses an entire container exclusively for their cargo. This option is ideal when you have enough goods to fill a container or when you want maximum security and faster handling.
Advantages of FCL shipping from China:
Lower cost per unit for large volumes
Reduced risk of damage or loss
Faster transit and fewer handling points
Easier customs clearance in many cases
CNXtrans specializes in FCL sea freight from China, helping importers choose the right container size and optimize loading to reduce costs.
LCL (Less than Container Load)
LCL is used when your shipment is too small to fill a full container. Your cargo is consolidated with shipments from other importers into one shared container.
Advantages of LCL shipping from China:
Lower upfront cost for small shipments
Ideal for startups, samples, or low-volume imports
Flexible shipping schedules
However, LCL can involve more handling, longer transit times, and additional consolidation fees.
This is where an experienced freight forwarder like CNXtrans becomes especially valuable, ensuring smooth consolidation and transparent pricing.
Container Types Used in Sea Freight from China
Choosing the correct container is essential for protecting your cargo and controlling shipping costs. Below are the most common container types used in sea freight from China.
Standard Dry Containers
These are the most widely used containers for general cargo.
20ft container: Suitable for heavy cargo or smaller volumes
40ft container: Ideal for large shipments with lighter goods
40ft High Cube (40HC): Offers extra height for increased capacity
CNXtrans helps importers determine the most cost-effective container size based on cargo dimensions, weight, and destination.
Refrigerated Containers (Reefer Containers)
Used for temperature-sensitive goods such as food, pharmaceuticals, and chemicals. These containers maintain controlled temperatures throughout the journey.
Open Top Containers
Designed for oversized or heavy cargo that cannot be loaded through standard container doors. Cargo is loaded from the top using cranes.
Flat Rack Containers
Used for machinery, vehicles, and irregularly shaped cargo. Flat racks have no side walls and are ideal for out-of-gauge shipments.
Tank Containers
Used for liquid cargo such as chemicals, oils, and food-grade liquids.
With CNXtrans, shippers receive expert advice on container selection to ensure cargo safety, compliance, and cost efficiency.

Step-by-Step Sea Freight Shipping Process from China
Understanding the shipping process helps importers avoid delays and unexpected costs. Below is a simplified breakdown of sea freight from China.
1. Booking with a Freight Forwarder
The process begins by booking your shipment with a freight forwarder like CNXtrans. At this stage, details such as cargo type, volume, destination, and Incoterms are confirmed.
2. Cargo Pickup and Inland Transportation
