The international logistics process for corporate shipments does not begin with the act of placing an order, but rather with the classification of the cargo's attributes. Whether the goods are classified as general cargo, sensitive cargo, or dangerous goods determines the available transport modes, customs clearance pathways, and the range of eligible carriers. For instance, products containing lithium batteries must meet specific packaging and documentation requirements for air transport, whereas pure liquid cargoes may face restrictions regarding Less-than-Container Load (LCL) shipping by sea. These classification decisions are based on the International Air Transport Association (IATA) Dangerous Goods Regulations, the International Maritime Organization (IMO) International Maritime Dangerous Goods (IMDG) Code, and the import control lists of the destination country. Enterprises must classify their goods prior to shipment; failure to do so may result in rejection at the point of origin or transit points, leading to additional warehousing and return shipping costs.
Once the cargo attributes are clearly defined, the process moves to selecting the appropriate mode of transport. International logistics primarily utilizes four main transport modes: sea, air, rail, and road. Sea freight is suitable for large volumes of non-time-sensitive cargo and operates via either Full Container Load (FCL) or Less-than-Container Load (LCL) arrangements. Air freight is ideal for high-value, small-volume, or urgent shipments, with billable weight calculated based on the higher of the actual weight or the volumetric weight. Rail transport-particularly for routes between China and Europe-offers greater capacity than air freight and faster transit times than sea freight, though it is constrained by route availability and port handling capacities. Road transport is predominantly used for cross-border shipments to neighboring countries or as a connecting leg in multimodal transport. When selecting a transport mode, enterprises must weigh factors such as cargo volume, weight, delivery deadlines, budget, and destination infrastructure, rather than focusing on a single metric in isolation.
After the transport mode is determined, the booking and container pickup phase begins. For sea freight, booking requires providing the shipping line or freight forwarder with details such as the cargo description, weight, volume, and the ports of origin and destination; once the booking is confirmed, arrangements are made to pick up the container. Air freight booking involves confirming flight space, documentation cut-off times, and cargo dimension limits. A key document at this stage is the shipping instruction (or booking request), which records details regarding the shipper, consignee, notify party, cargo description, and freight payment terms. The information on the shipping order must be consistent with subsequent customs declarations and bills of lading; otherwise, document discrepancies may arise during customs clearance at the destination port. Enterprises should note that document submission deadlines vary by shipping line or airline; missing a deadline can result in the cargo being delayed until the next scheduled voyage.
Cargo stuffing and delivery to the port (or consolidation) represent the phase involving the most intensive physical operations. Stuffing can be performed either at the factory or at a container yard. Factory stuffing is carried out at the enterprise's own warehouse; this requires photographing the container when empty, half-full, and fully loaded, as well as recording the seal number. Yard stuffing is performed by the carrier at a designated location, requiring the enterprise to transport the goods to the specified warehouse. During stuffing, factors such as weight distribution, moisture protection, and shock absorption must be considered to prevent damage caused by cargo shifting during transit. Delivery to the port involves transporting containers or break-bulk cargo to designated areas at the port or airport to await loading onto the vessel or aircraft. Once delivered, the cargo enters a customs-supervised zone; at this stage, the enterprise cannot retrieve the goods at will without completing formal customs withdrawal procedures.
Customs declaration and inspection are the most strictly regulated aspects of the international logistics process. Customs declaration involves submitting cargo details-such as the HS code, quantity, value, country of origin, and trade mode-to customs authorities. The HS code determines the export tax rebate rate and regulatory requirements. Inspection applies to goods subject to mandatory inspection or quarantine requirements imposed by the importing country (e.g., providing a fumigation certificate for wooden packaging). Declaration methods include self-declaration and agency declaration. Self-declaration requires the enterprise to possess the necessary qualifications and professional staff, whereas agency declaration involves outsourcing the task to a customs broker. Regardless of the method, the enterprise must provide contracts, invoices, packing lists, and a power of attorney for customs declaration. After reviewing the documents, customs may conduct an inspection, which can involve machine scanning or manual container opening. If no irregularities are found, the goods are released; otherwise, document amendments or additional documentation may be required.
Once released, the cargo enters the main transport phase. In ocean freight, vessels operate on fixed routes, and enterprises can track container status via the shipping line's website or through their freight forwarder. In air freight, cargo is transported via direct flights or scheduled transits. Rail transport requires a gauge change at border crossings; due to the difference in track gauges between China and Europe, containers must be lifted and transferred to trains operating on the different gauge at border stations. Road transport involves cross-border entry and exit inspections. Time fluctuations during this stage primarily stem from weather conditions, port congestion, strikes, or route adjustments. Companies must build in buffer time to avoid incurring container or port demurrage charges at the destination due to transport delays.
Upon arrival at the destination port, the process moves to customs clearance and cargo pickup. The consignee or their agent handles customs clearance by declaring the shipment to local authorities and submitting documents such as the bill of lading, commercial invoice, packing list, and certificate of origin. Customs requirements vary significantly by country; for instance, some nations require importers to hold a tax ID, while others impose anti-dumping duties on specific goods. Once clearance is complete, the consignee must exchange documents for a delivery order and settle destination charges, including terminal handling fees, document exchange fees, and any applicable demurrage. During pickup, the container seal number must be verified against the bill of lading; any discrepancies should be documented and photographed on the spot.
"Last-mile delivery" constitutes the final stage of international logistics, involving the transport of goods from the destination port warehouse or yard to the consignee's designated address. Delivery methods include express courier, Less-than-Truckload (LTL), and Full Truckload (FTL). Express courier is suitable for small parcels; LTL is ideal for multiple small-batch shipments; and FTL is best for large-volume, direct shipments. Delivery timeliness depends on local traffic conditions, address accuracy, and the consignee's availability. Companies should verify the consignee's address format, contact number, and delivery time window prior to shipment to avoid incurring re-delivery fees caused by failed delivery attempts.
