Sea Freight Process from China: Step-by-Step Export Guide (2026)

Back to All Guides

1. Overview: Sea freight export process from China

Sea freight from China accounts for approximately 90% of global containerized trade by volume, with Chinese ports handling over 260 million TEU annually. The export process from a Chinese factory to an overseas destination involves seven distinct steps, each with its own documentation, timing, and compliance requirements. A freight forwarder manages steps 2 through 7 on behalf of the shipper, who is typically the exporter or the overseas buyer depending on the Incoterms agreed in the sales contract.

The total door-to-door timeline for sea freight from China ranges from 25 days (Shanghai to Los Angeles, FCL) to 55+ days (inland China factory to European inland destination, LCL). The single biggest variable is not ocean transit time but the documentation and customs clearance phases at both origin and destination. Delays in customs clearance or incorrect VGM declarations are the most common causes of missed vessel connections.

FCL vs LCL: Which one to choose

The first operational decision in any sea freight shipment from China is whether to ship Full Container Load (FCL) or Less than Container Load (LCL). The decision is driven by cargo volume and cost per unit.

Factor	FCL (Full Container Load)	LCL (Less than Container Load)
Best for	Cargo above 15 CBM	Cargo 1-10 CBM
Container capacity	20ft: ~28 CBM; 40ft: ~58 CBM; 40HC: ~68 CBM	Pay per cubic meter used
Transit time penalty	None: direct vessel loading	Add 3-7 days for consolidation + deconsolidation
Cost structure	Flat rate per container	Per-CBM rate (includes consolidation fee)
Cargo security	Sealed container, single shipper	Shared container, multiple shippers
Damage risk	Lower: container sealed at origin	Higher: cargo handled during consolidation/deconsolidation

FCL and LCL cost benchmarks (from China, 2026 Q1-Q2)

Route	FCL 20ft (Low Season)	FCL 20ft (Peak Season)	LCL (per CBM)
China → USA West Coast	$2,500-5,000	$6,000-12,000	$80-160
China → USA East Coast	$4,000-7,000	$8,000-15,000	$100-180
China → UK / North Europe	$1,500-4,000	$5,000-9,000	$70-150
China → Southeast Asia	$500-1,500	$1,500-3,000	$30-80
China → Middle East	$1,500-3,500	$3,500-7,000	$60-120

2. Step 1: Sourcing and supplier coordination

Sourcing and supplier coordination is the foundation of any sea freight export from China. This step covers negotiating with Chinese suppliers, confirming production timelines, and agreeing on the Incoterms rule that determines who pays for and arranges each segment of transport. Most Chinese suppliers quote on FOB (Free On Board) terms by default, which means the supplier is responsible for getting cargo to the named port and clearing China export customs, while the buyer arranges and pays for the ocean freight and destination charges.

Key supplier coordination checkpoints

• Confirm the Incoterms rule in the sales contract. Under Incoterms 2020 (the current version published by the International Chamber of Commerce), FOB is the most common Incoterm offered by Chinese suppliers. EXW (Ex Works) puts all transport responsibility on the buyer from the factory gate. DAP (Delivered at Place) means the Chinese seller manages transport to the named destination.
• Verify production schedule and cargo ready date. Book freight only after you have a confirmed cargo ready date. Pre-booking without confirmed cargo leads to dead freight charges or container detention fees if production slips. Chinese factories typically need 2-4 weeks lead time for standard goods, 4-8 weeks for DG or specialized equipment.
• Request product specifications and HS codes. The HS (Harmonized System) code determines customs duty rates at destination and whether the goods require special permits. Confirm the correct 6-digit or 10-digit HS code from the supplier before booking.
• Check destination import restrictions. For US-bound goods, the UFLPA (Uyghur Forced Labor Prevention Act) requires supply chain documentation proving goods are not produced with forced labor. For EU-bound goods, CBAM carbon reporting is required for steel, aluminum, and cement imports from 2026. Your freight forwarder can advise on destination compliance requirements.
• Confirm packaging specifications. Sea freight cargo must be packed for container transit: moisture protection, stackability, and secure internal bracing. Export-standard packaging differs from domestic packaging. If the supplier uses domestic packaging, arrange repacking at a Qingdao or Shanghai CFS before loading.

3. Step 2: Booking and Incoterms 2020

Booking is the process of reserving container space on a specific vessel sailing. This step is typically handled by your freight forwarder, who books directly with the shipping line (carrier). The booking confirmation includes: vessel name, voyage number, estimated departure date (ETD), estimated arrival date (ETA), container type and quantity, and the port of loading and discharge.

Incoterms 2020: Who pays for what

Incoterm	Supplier Responsibility	Buyer Responsibility	Best For
EXW	Make goods available at factory	All transport, customs, insurance	Buyers with established China logistics
FOB	Deliver to port, China export customs	Ocean freight, destination costs	Most common for sea freight from China
CIF	FOB + ocean freight + insurance	Destination customs, delivery	Buyers wanting supplier-managed shipping
DAP	All transport to named destination	Import customs, duties	Door-to-door from China supplier
DDP	All costs including import duties	Receive goods	Full-service from Chinese seller

The booking process timeline

1. Send cargo details to forwarder (7-14 days before cargo ready date): commodity, HS code, total CBM/weight, number of packages, pick-up address, destination port or door.
2. Forwarder provides quotation (within 24 hours): ocean freight rate, local charges at origin (THC, documentation, customs brokerage, trucking), and destination charges breakdown.
3. Confirm booking (at least 5-7 days before ETD for FCL, 7-10 days for LCL). LCL needs extra lead time because consolidation requires cargo from multiple shippers to arrive at the CFS before the cut-off date.
4. Receive booking confirmation with vessel details and container release reference. The forwarder sends this to the trucking company for empty container pick-up at the carrier's designated depot.

4. Step 3: Container loading and VGM

Container loading is the physical process of stuffing cargo into a container and preparing it for sea transit. For FCL, this happens at the supplier's factory (factory-loaded) or at a Container Freight Station (CFS) near the port. For LCL, cargo is delivered to the forwarder's CFS for consolidation with other shippers' cargo. After loading, the VGM (Verified Gross Mass) must be declared before the container can enter the port terminal gate.

FCL loading options

• Factory loading (most common). The shipping line releases an empty container to the trucker, who delivers it to the supplier's factory. The factory loads the container, seals it, and the trucker hauls the loaded container to the port. This is the preferred method because the container is sealed at origin, reducing risk of tampering and damage.
• CFS loading. Cargo is transported loose (uncontainerized) to a CFS near the port. The forwarder arranges container stuffing at the CFS. This is used when the factory lacks loading equipment (forklifts, loading dock) or when cargo from multiple suppliers is consolidated into one FCL.

LCL loading process

For LCL, the supplier delivers cargo (usually by truck) to the forwarder's designated CFS. The forwarder consolidates cargo from multiple shippers into one container. Each shipper's cargo is separated inside the container (typically by physical barriers or marked labels) and receives a separate House Bill of Lading (HBL). LCL consolidation adds 3-7 days total: 2-4 days at origin CFS before loading, and 1-3 days at destination CFS for deconsolidation. See our LCL shipping from China guide for detailed LCL transit times by route.

VGM (Verified Gross Mass): SOLAS requirement

Under the SOLAS (Safety of Life at Sea) convention, every packed container must have a Verified Gross Mass (VGM) declared before it can be loaded onto a vessel. This rule has been in effect globally since July 1, 2016. The VGM is the total weight of the container + cargo + packaging + securing materials. There are two methods to obtain VGM:

• Method 1: Weigh the packed container on a calibrated scale at the factory or at the terminal gate.
• Method 2: Weigh all cargo and packaging separately, then add the tare weight of the empty container (marked on the container door).

VGM must be submitted to the carrier and terminal before the VGM cut-off deadline, typically 24-48 hours before vessel ETD depending on the port. Containers without a valid VGM are not permitted to enter the terminal gate. No exceptions. At Qingdao port, VGM is submitted electronically through the port's EDI system by the freight forwarder.

5. Step 4: China export customs clearance

China export customs clearance is the process of declaring goods for export through China Customs using the China Single Window (单一窗口) electronic system. According to the China Ministry of Transport (MOT), over 50 million customs declarations were processed through the Single Window in 2025, with more than 80% receiving automated clearance within minutes. This step must be completed before the container can enter the port terminal (for Shanghai Yangshan) or before the vessel departure (for other terminals that allow post-arrival clearance). The customs declaration is submitted by a licensed Chinese customs broker, typically arranged by your freight forwarder.

Customs declaration documents required

• Export customs declaration form (出口货物报关单), submitted electronically via China Single Window.
• Commercial invoice showing seller, buyer, HS code, quantity, unit price, total value, Incoterms, and currency.
• Packing list detailing each package: dimensions, weight, contents.
• Contract or purchase order between exporter and buyer.
• Export license (if applicable), required for controlled commodities such as certain chemicals, dual-use items, or restricted raw materials.
• Certificate of origin (if applicable), required if the destination country offers tariff preferences under a free trade agreement with China.

Customs clearance timeline and terminal specific rules

Standard China customs clearance takes 1-2 working days for routine cargo. According to the China Port and Harbor Association, Qingdao and Shanghai are the top two ports for export customs processing efficiency. However, key Chinese ports have different operating procedures that affect the sequence:

• Shanghai Yangshan deep-water terminal: customs clearance must be completed BEFORE the container enters the terminal gate. This means the customs broker submits the declaration 2-3 days before vessel ETD, obtains the customs release, and the trucker then delivers the container to Yangshan.
• Shanghai Waigaoqiao terminals: allow post-arrival clearance. The container can enter the terminal first, and customs clearance can proceed while the container is in the terminal yard, as long as it is completed before vessel loading.
• Qingdao port (all terminals): customs clearance before port entry is standard. Qingdao customs release is integrated with the terminal gate system, so the container is not admitted without a customs release.

Customs inspection (查验)

Approximately 5-10% of export declarations are selected for customs inspection. If selected, the container is moved to a customs inspection area. Standard inspection takes 1-2 working days and may require unloading the container for physical examination of goods. Inspection results in either a "release" (放行) or "hold" (扣留) status. A full inspection of a 40ft container in Qingdao typically costs RMB 500-1,000 in terminal handling fees, excluding any duty or penalty if discrepancies are found.

6. Step 5: Port entry and vessel loading

Port entry is the process of delivering the loaded container to the terminal gate and having it received into the terminal yard for vessel loading. The trucker arrives at the terminal with the container, driver's ID, container number, seal number, booking number, and VGM. The terminal gate system verifies customs release status and VGM, weighs the container (for Method 1 compliance or spot-checking), and directs the trucker to the assigned yard block for container drop-off. At Qingdao port, this entire gate process averages 30-45 minutes, longer during peak gate hours (09:00-11:00, 14:00-16:00).

Terminal cut-off times

Every vessel has a terminal cut-off time. This is the latest time a container can be received at the terminal gate and still make the vessel loading plan. Cut-off times vary by terminal and typically range from 12 to 24 hours before vessel ETD:

Port	Standard Terminal Cut-Off	DG Cargo Cut-Off
Qingdao (QQCT)	12 hours before ETD	24 hours before ETD
Shanghai (Yangshan)	12 hours before ETD	24 hours before ETD
Ningbo	12 hours before ETD	24 hours before ETD
Shenzhen (Yantian)	8 hours before ETD	24 hours before ETD
Tianjin	12 hours before ETD	24 hours before ETD

Vessel loading sequence

Once the container is in the terminal yard, the terminal's planning system assigns it to a vessel stowage position. The container is moved from the yard to the quayside by internal terminal vehicles (yard tractors), then loaded onto the vessel by ship-to-shore gantry cranes. This process typically happens within 4-8 hours of vessel departure. After loading, the container status updates to "loaded on board" in the carrier's tracking system, and the Bill of Lading can be issued. The B/L is the most important shipping document: it serves as a receipt for the goods, evidence of the contract of carriage, and a document of title (for negotiable B/Ls).

7. Step 6: Ocean transit and cargo tracking

Ocean transit is the period from vessel departure at the Chinese port of loading to vessel arrival at the destination port. Transit times vary by route, carrier, and whether the vessel sails direct or transships. Below are benchmark transit times from major Chinese ports.

Sea freight transit times from China (FCL, direct service)

Route	FCL (Direct)	LCL (Includes Consolidation)	Key Destination Ports
China → USA West Coast	12-16 days	28-38 days total	Los Angeles, Long Beach, Oakland, Seattle
China → USA East Coast	25-30 days	35-45 days total	New York, Savannah, Norfolk, Charleston
China → North Europe	28-35 days	30-40 days total	Rotterdam, Hamburg, Antwerp, Felixstowe
China → Mediterranean	25-32 days	30-38 days total	Barcelona, Genoa, Piraeus, Valencia
China → Southeast Asia	5-12 days	10-18 days total	Singapore, Port Klang, Laem Chabang, Jakarta
China → Middle East	16-22 days	22-28 days total	Jebel Ali, Dammam, Sohar
China → Australia	14-20 days	20-28 days total	Sydney, Melbourne, Brisbane, Fremantle

China-Europe freight train as a sea freight alternative

The China-Europe Railway Express (中欧班列 / CRE) is an alternative to sea freight for time-sensitive cargo to Europe and Central Asia. The Xi'an to Duisburg service runs 4 trains per week westbound, with a fastest transit of 12 days and standard transit of 17-20 days. This is approximately half the time of sea freight (28-35 days) but costs 2-3x more per container. The Middle Corridor via Kazakhstan, Azerbaijan, Georgia, and Turkey is another option avoiding Russia. For DG cargo, rail operators have varying DG acceptance policies; our team can advise on rail vs sea routing for your cargo type.

Short-sea feeder services from Qingdao

For Northeast Asia destinations, short-sea services provide frequent connections: Qingdao to Busan takes 1-2 days by feeder vessel, and Qingdao to Vladivostok takes 3-5 days. These short-sea routes are ideal for Northeast Asia bonded transit via Qingdao's bonded logistics park, where cargo can be consolidated, stored, and transshipped without paying Chinese import duties.

Cargo tracking during ocean transit

Most major carriers (MSK, HPL, MSC, COSCO, HMM, OOCL, EMC, YML, CMA CGM) provide online container tracking by booking number, B/L number, or container number. Your freight forwarder should provide daily or per-event status updates. Standard tracking events include: gate-in at terminal, loaded on board, vessel departure, vessel arrival at transshipment port (if applicable), vessel departure from transshipment port, vessel arrival at destination, container discharged, and container available for pick-up.

8. Step 7: Destination customs and delivery

Destination customs clearance and delivery is the final step. The process varies significantly by destination country, but follows a common sequence: (1) pre-arrival customs filing, (2) arrival notification, (3) customs clearance with duties and taxes, (4) cargo release, (5) trucking or rail delivery to final consignee.

Destination-specific requirements

• European Union: ENS (Entry Summary Declaration). ENS must be filed before vessel departure from the last non-EU port. Late filing penalties increased to 2,500 euros in 2026 (up from 1,000 euros). For DG shipments, the ENS filing requires additional fields including the UN number and IMDG class. CBAM (Carbon Border Adjustment Mechanism) reporting is mandatory from 2026 for steel, aluminum, cement, fertilizer, electricity, and hydrogen imports.
• United States: UFLPA compliance. US Customs and Border Protection (CBP) enforces the Uyghur Forced Labor Prevention Act. Importers must demonstrate that goods produced in whole or in part in Xinjiang, or by entities on the UFLPA Entity List, are not entering the US supply chain. Supply chain documentation tracing raw materials to source is required. CBP has detained over $3 billion in goods under UFLPA since its enactment. ISF (Importer Security Filing, "10+2") must be filed 24 hours before vessel loading at the origin port.
• Bonded warehousing as a customs strategy. For importers who want to defer duties, manage cash flow, or stage inventory for just-in-time distribution, bonded warehousing allows storage of imported goods without paying duties until they are released into free circulation. This applies at destination countries too: many importers use bonded warehouses at major ports (Rotterdam, Los Angeles, Dubai) to hold inventory until needed.

Destination delivery terms

Delivery at destination covers several charge items that buyers should budget for. Even under CIF terms (where the supplier pays ocean freight and insurance), the buyer is responsible for destination charges: terminal handling charges at destination port (THD), customs brokerage fee, import duties and VAT, delivery order fee, trucking to final delivery address, and container deposit (refundable after empty container return). For FCL, the buyer typically has 5-7 free days of container detention from the day of discharge. After that, detention charges apply: approximately $50-150/day depending on carrier and container type. For oversized or project cargo, destination delivery requires additional planning for heavy-lift equipment (mobile cranes, low-bed trailers) and route surveys for road transport.

9. Documents checklist for sea freight export from China

Sea freight from China requires a specific set of documents at each stage of the export process. Missing or incorrect documents are the leading cause of delays, terminal storage charges, and missed vessel sailings.

Standard export documents (all shipments)

#	Document	Issued By	When Required
1	Commercial Invoice	Exporter/Supplier	Before customs declaration
2	Packing List	Exporter/Supplier	Before customs declaration
3	Export Customs Declaration	Customs broker (submitted to China Customs)	Before port entry (Yangshan/QQCT) or before vessel departure
4	Bill of Lading (B/L)	Shipping line or forwarder	After vessel departure; required for destination release
5	VGM Declaration	Shipper (submitted via forwarder)	Before terminal cut-off
6	Certificate of Origin	CCPIT or CIQ	Before destination customs (if claiming FTA tariff preference)

Additional documents for dangerous goods

#	Document	Issued By	When Required
7	DG Classification Report (危险品分类鉴定报告)	Certified lab (e.g., Shanghai Research Institute of Chemical Industry)	Before booking; 5-7 working days to obtain
8	DG Packaging Certificate (危包证)	Local CIQ	Before port entry; 7-10 working days to obtain
9	MSDS (Material Safety Data Sheet)	Manufacturer	Before booking
10	Maritime DG Declaration (海运危险货物申报单)	Forwarder submits to MSA	3 working days before vessel ETD

For IMDG Code compliance from 2026, MSDS Section 14 must reference IMDG Code Amendment 42-24 (mandatory from January 1, 2026). Documents citing the previous Amendment 41-22 are rejected by carriers and MSA. For sodium-ion battery shipments (UN3551, UN3552), Amendment 42-24 requires a full Dangerous Goods Declaration (DGD) and SEA CERT, which were not required under the previous amendment. See our DG freight services for complete DG documentation support.
