In a globally integrated economy, international trade demand is expanding rapidly. Alongside familiar modes like road and air transport, sea freight has become the top choice for the majority of businesses. Not only does it solve the challenge of transporting massive volumes, but it also helps optimize profits through cost-effective shipping rates.

Analysis of International Sea Freight

Sea freight holds a dominant position in the logistics industry for several reasons. To understand why, let’s analyze its core advantages and limitations.

Key Advantages

Ocean transport possesses unique characteristics that road and air freight struggle to match:

  • Oversized & Overweight Capacity: It is the only method perfectly suited for bulky, out-of-gauge (OOG) cargo, such as industrial machinery and production lines.

  • Cost Optimization: Sea freight rates are significantly lower than air or road transport, serving as a key factor in reducing the final price of products.

  • Stable Routing: Ships move along designated maritime lanes with fewer interruptions compared to road transport, ensuring a steady flow.

  • Global Reach: This method allows for the transport of large quantities of goods to countries and territories across vast geographical distances from Vietnam.

Types of Goods Transported by Sea

One of the most prominent features of sea freight is its ability to accept almost all types of goods (except prohibited items). At Thai Ha Transport, we frequently handle the following groups:

  • General Cargo: Fashion, textiles, and footwear.

  • Food & Agricultural Products: Frozen goods, confectionery, agricultural produce, spices, tea, and tobacco (with strict monitoring of temperature and humidity).

  • Furniture & Handicrafts: Ceramics, glassware, and wooden furniture.

  • Technology & Electronics: Computers, smartphones, laptops, and electronic components.

  • Heavy Industrial Goods: Industrial machinery, spare parts, production lines, and construction materials (iron, steel, etc.).

  • Specialized Goods: Powders prone to dusting or highly hygroscopic (moisture-absorbing) goods.

  • Dangerous Goods (DG): Chemicals, solutions, and products containing batteries.

Calculating Cargo Volume in Sea Freight

In international shipping, cargo volume is determined by both weight and measurement (CBM). The freight is usually calculated based on whichever value is higher.

Container Capacity Estimation

To estimate the number of packages per container, we use the following standard usable volumes:

  • 20′ Container: $Quantity = \frac{28}{Unit \text{ Volume } (m^3)}$

  • 40′ Container: $Quantity = \frac{60}{Unit \text{ Volume } (m^3)}$

  • 40′ HC (High Cube): $Quantity = \frac{60}{Unit \text{ Volume } (m^3)}$ (Note: Subject to specific packing requirements)

Formulas

  • Unit Volume (CBM): $Volume = Length \times Width \times Height \text{ (m)}$

  • Volumetric Weight: $Weight \text{ (Kgs)} = \frac{Length \times Width \times Height \text{ (cm)}}{5000}$

Example: If a package has dimensions 0.31m x 0.32m x 0.55m, its volume is $0.05456 \text{ CBM}$.

Key Considerations for Sea Freight Shipping

To ensure a smooth shipping process and avoid legal or financial risks, please keep the following in mind:

  1. Compliance: Strictly avoid prohibited items such as narcotics or endangered species as per international and local laws.

  2. Contract Review: Carefully check all information in the transport contract. This is your legal protection in case of disputes.

  3. Cargo Insurance: For high-value goods or long-distance routes, purchasing insurance is highly recommended to protect against financial loss due to unforeseen incidents.

  4. Method Selection: Evaluate your cargo volume carefully to choose between LCL and FCL to optimize costs.
