Martin Damboldt

What is Ocean Freight? 

Ocean freight, often referred to as sea freight, is the backbone of international trade, serving as a fundamental method for transporting goods across the world’s oceans and seas. This mode of transportation involves the loading and shipment of cargo on ships, which come in various types, including container ships, bulk carriers, and specialised vessels for specific cargo types.  

Breaking Down the Ocean Freight Process: A Detailed Overview 

International ocean freight shipping is a complex process that involves several crucial steps, each of which plays a vital role in ensuring the successful transportation of goods across the world’s oceans and seas. Let’s break down this process into detailed subheadings: 

Cargo Preparation 

  • The journey of an ocean freight shipment begins with the shipper or exporter preparing the cargo for transport. 
  • Effective packaging is vital for safeguarding goods during transportation, guaranteeing they arrive at their destination in prime condition. 
  • Labelling is crucial to identify the cargo and its destination accurately. 
  • Documentation must comply with international regulations and requirements, including bills of lading, invoices, certificates of origin, and other necessary paperwork. 

Cargo Transportation to the Port of Origin 

  • Once the cargo is ready for shipment, it is transported to the designated port of origin. 
  • This involves coordinating the logistics of moving the cargo from the shipper’s location to the port, which can include various modes of inland transportation such as trucks or trains. 

Customs Clearance at the Port of Origin 

  • At the port of origin, the cargo undergoes customs clearance procedures.  
  • Customs officials review the paperwork and examine the cargo to ensure that it adheres to export regulations and that the provided information is accurate. 

Cargo Loading onto Ocean Vessel 

  • After customs clearance, the cargo is loaded onto the selected ocean vessel. 
  • This process requires careful handling and organization to optimize space within the vessel and secure the cargo for the journey. 

The Ocean Voyage 

  • Once on board the ocean vessel, the cargo embarks on its voyage across the ocean. 
  • The vessel follows a predetermined route, navigating through various international waters and making stops at different ports of call along the way.

Arrival at Destination Port

  • Upon reaching the destination port, the cargo undergoes customs procedures once more. 
  • Customs officials at the destination review the documentation, inspect the cargo, and ensure that all import regulations are met. 

Customs Clearance at Destination Port 

  • The cargo’s clearance at the destination port is critical for entry into the destination country. 
  • Any necessary duties, taxes, or tariffs must be paid, and import documentation must be completed accurately. 

Delivery to the Consignee or Importer 

  • Once customs clearance is obtained at the destination port, the cargo is released for delivery. 
  • The consignee or importer receives the goods and takes possession of the cargo.

Incoterms Used in Ocean Shipping 

Incoterms, or International Commercial Terms, define the responsibilities of buyers and sellers in international trade. Understanding these terms is crucial for successful ocean freight transactions. 

Here are some common Incoterms used in ocean shipping: 

FOB (Free On Board): Seller delivers goods to the named port of shipment, and risk/cost transfers to the buyer at that point. 

CIF (Cost, Insurance, and Freight): Seller pays for cost, insurance, and freight to the named port of destination; risk transfers once goods are on the vessel. 

CFR (Cost and Freight): Seller covers cost and freight to the named port of destination; buyer arranges insurance. 

EXW (Ex Works): Seller’s responsibility ends at their premises; buyer bears all subsequent costs and risks. 

DAP (Delivered At Place): Seller delivers goods to a named place of destination (unloaded); buyer assumes risk and cost from there. 

DDP (Delivered Duty Paid): Seller handles all costs, risks, and duties/taxes to deliver goods to the buyer’s premises or named place. 

DAT (Delivered At Terminal): Seller delivers unloaded goods to a named terminal at the destination; risk transfers upon unloading. 

DPU (Delivered at Place Unloaded): Seller delivers unloaded goods to a named place of destination; risk transfers upon unloading. 

What affects ocean freight rate? 

Fuel Costs: Fuel prices, particularly the cost of bunker fuel, have a significant impact on ocean freight rates. Fuel prices can fluctuate due to global oil market dynamics and regulatory changes in environmental standards. 

Demand and Supply: The basic principle of supply and demand plays a crucial role in ocean freight rates. When demand for shipping space exceeds supply (e.g., during peak seasons), rates tend to rise. Conversely, in periods of oversupply, rates may decrease. 

Vessel Capacity: The size and availability of container vessels affect rates. Larger vessels can carry more cargo, potentially reducing rates, while shortages of vessel capacity can drive rates higher. 

Economic Conditions: Economic factors, including GDP growth, trade volumes, and consumer demand, impact the flow of goods and, consequently, ocean freight rates. 

Geopolitical Events: Political instability, trade disputes, sanctions, and other geopolitical events have the potential to disrupt shipping routes, introducing uncertainty and altering trade patterns, which can subsequently impact shipping rates. 

Port Congestion: Congestion at ports, caused by factors like labor strikes, infrastructure limitations, or adverse weather conditions, can lead to delays and increased costs, affecting rates. 

Trade Routes: The specific trade routes used for shipping can affect rates, as some routes may be more efficient and cost-effective than others. 

Type of Cargo: The nature of the cargo being shipped can also impact rates. Cargo characteristics such as size, weight, value, and special handling requirements can affect the cost of shipping. 

Environmental Regulations: Environmental regulations, including emissions standards and carbon pricing, may raise operational costs for shipping firms, potentially resulting in increased rates. 

How are ocean freight costs calculated? 

Calculating ocean freight costs can be complex, as it involves multiple components that contribute to the final price. Here’s an overview of how ocean freight costs are typically calculated: 

Base Freight Rates: Base freight rates are the core charges for transporting cargo from one port to another. Ocean freight rates are determined by several factors, including supply and demand dynamics, port-to-port distances, vessel specifications, and chosen trade routes. Base rates are usually quoted per twenty-foot equivalent unit (TEU) for containers or per freight ton for bulk or breakbulk cargo. 

Surcharges: Surcharges are additional costs applied on top of the base rates. They can significantly impact the total freight cost. 

Common surcharges include:  

Bunker Adjustment Factor (BAF): Reflects fluctuations in fuel prices.  

Currency Adjustment Factor (CAF): Compensates for currency exchange rate variations.  

Peak Season Surcharge (PSS): Applied during peak shipping seasons.  

Low Sulphur Surcharge (LSF): Levied to comply with environmental regulations.  

Emergency Bunker Surcharge (EBS): An additional fuel surcharge in response to extraordinary fuel price increases. 

Accessorial Charges: These are fees for additional services or specific cargo handling requirements. Examples include demurrage (charges for exceeding free time at the port), detention (charges for holding containers longer than allowed), and reefer (refrigerated container) charges. 

Container Costs: Shippers may need to pay container-related fees, including container leasing costs and container handling charges at the ports. 

Terminal Handling Charges (THC): THC fees are assessed by the port or terminal for loading and unloading cargo from the vessel. These charges vary by port and can depend on cargo size, weight, and handling requirements. 

Bill of Lading (B/L) Fees: The issuance of a bill of lading, which serves as the contract of carriage, involves associated fees. 

Documentation and Administration Fees: Costs related to customs documentation, cargo insurance, and other administrative tasks may apply. 

Destination Charges: These are fees associated with transporting cargo from the destination port to its final delivery location, including drayage (local transportation) and delivery charges. 

Additional Services: Charges for special services, such as cargo inspection, fumigation, or customs clearance, can also be part of the overall cost. 

What is the country-specific requirements in ocean freight shipping? 

Customs Documentation: Every nation has its specific customs documentation and paperwork prerequisites. These usually encompass items like the commercial invoice, packing list, bill of lading, certificate of origin, and any obligatory permits or licenses. 

Tariffs and Duties: Import duties and tariffs vary widely from one country to another. Shippers need to understand the specific duties applicable to their goods in the destination country and plan for these costs. 

Restricted and Prohibited Goods: Different countries have restrictions or prohibitions on the import or export of certain goods. Shippers should check the destination country’s regulations to ensure their cargo is compliant. 

Product Standards and Labelling: Some countries have specific product standards and labelling requirements that must be met for imports. These may relate to safety, quality, and product labelling in the local language. 

Documentation Language: Some countries may require that all shipping and customs documents be in their official language or translated accordingly. 

Sanitary and Phytosanitary Requirements: For agricultural and food products, there may be strict sanitary and phytosanitary (SPS) requirements that must be met to prevent the introduction of pests and diseases. 

Licensing and Certification: Certain goods may require special licenses or certifications for importation, such as pharmaceuticals, chemicals, or hazardous materials. 

Import Quotas and Restrictions: Certain nations implement import quotas or restrictions on particular products, constraining the allowable quantity for importation during a designated timeframe. 

Compliance with International Trade Agreements: Countries that are party to international trade agreements may have specific requirements for goods originating from member countries, such as preferential tariff rates. 

Inspection and Examination: Some countries may conduct random inspections or examinations of imported goods, which can add time and costs to the shipping process. 

Customs Brokerage: Utilising the services of a licensed customs broker who is familiar with the destination country’s regulations can help ensure compliance and expedite customs clearance. 

Conclusion 

International ocean freight shipping is a complex yet essential aspect of global trade. Understanding the process, making informed decisions about cargo type and container options, and staying abreast of industry trends and regulations are key to successful international shipments.
