Introduction
Shipping goods from China to the United States by ocean is one of the most cost-effective ways to move large volumes of products. It is also one of the most complex, involving multiple parties, strict documentation, and tight timelines. Whether you are a growing Amazon seller or a traditional importer, understanding how ocean freight works will help you avoid delays, reduce costs, and protect your cargo from unnecessary risk.
Understanding Ocean Freight from China to the US
Most ocean shipments from China to the US depart from major ports such as Shenzhen, Guangzhou, Shanghai, Ningbo, and Qingdao, and arrive at major US gateways like Los Angeles, Long Beach, Oakland, Seattle, New York/New Jersey, Savannah, and Houston.
You can usually choose between two main modes: full-container-load (FCL) and less-than-container-load (LCL). FCL means you book an entire container for your goods, even if it is not completely full. It is often more economical and safer for larger volumes. LCL combines your cargo with shipments from other buyers in the same container, which is great for smaller volumes but may involve slightly longer handling times and more touch points.
Key Steps in the China–US Ocean Shipping Process
The basic flow of a shipment looks like this:
Your supplier prepares the goods and export documents, such as the commercial invoice, packing list, and sometimes a certificate of origin. Your freight forwarder books a sailing with a shipping line and arranges first-leg transportation from the factory to the origin port or consolidation warehouse. At origin, the goods are inspected if required, loaded into a container, and cleared through Chinese customs for export.
Next comes the ocean leg. Transit times vary depending on port pairs and service type. For example, South China to US West Coast can be around two to three weeks on the water, while South China to US East Coast via the Panama Canal or Suez route can take closer to four to six weeks. After arrival, the container is unloaded, and the shipment goes through US customs clearance and any necessary inspections. Once cleared, the goods are either sent to an overseas warehouse, an Amazon fulfillment center, or directly to your final delivery address for last-mile distribution.
Documentation You Must Get Right
Paperwork is one of the biggest sources of delays and extra costs. At minimum, you should expect to work with a commercial invoice, packing list, bill of lading, and any licenses or permits required for regulated products. Product descriptions must be accurate, HS codes should be correct, and declared values need to be realistic and consistent across all documents.
Incorrect HS codes can lead to higher duties, penalties, or customs holds. Under- or over-declaring values can trigger inspections or fines. Working with a forwarder who understands both Chinese export rules and US customs requirements can significantly reduce these risks.
Cost and Transit Time Factors
Ocean freight prices are not fixed and can change with seasons, fuel costs, port congestion, and global demand. Your final landed cost will typically include origin charges (such as trucking and export handling), ocean freight, destination charges (like terminal handling and documentation), customs duties and taxes, and domestic delivery.
Transit time is not just “time on the water.” You also need to factor in factory handling, trucking to port, waiting for a vessel, port operations, customs clearance, and final delivery. Having a realistic schedule helps you plan inventory levels, avoid stockouts, and choose the right shipping windows for peak seasons like Q4.
Common Pitfalls to Avoid
Many importers underestimate how early they need to book during peak seasons, assume the cheapest rate is always the best, or overlook the importance of packaging standards for long sea journeys. Poor packaging can lead to carton collapse, water damage, or product breakage when containers face humidity and movement at sea.
Another common mistake is failing to coordinate Incoterms properly with the supplier. For example, if you buy under EXW or FOB terms without a trusted forwarder, you may face hidden origin charges or lose control over timelines and documents. Choosing a partner who offers transparent pricing and full-chain visibility helps you avoid surprise fees and miscommunication.
Why Work with a Professional Logistics Partner
