Container Shipping

What is Container Shipping?

Container shipping is the backbone of modern global trade. It is a standardized method of transporting goods that uses so-called intermodal shipping containers. These containers can be easily moved between different types of transport (maritime, rail, road) without needing to manipulate the cargo inside. The key benefits are efficiency, safety, speed, and reduced costs.

The essence of containerization:

Standardization: ISO standards determine the dimensions, load capacities, and handling points of containers.
Intermodality: Containers can be transferred between ships, trains, and trucks without unpacking the cargo.
Efficiency: Enables fast and safe loading and unloading of large volumes of goods.
Safety: Steel containers protect goods from damage, theft, and weather.
Scalability: The system supports enormous volumes of transport – today over 20 million containers are in circulation.

Development and Revolution in Container Shipping

Before Containerization

Problem	Description
Low efficiency	Piece-by-piece transport, labor-intensive manual handling, long port delays
High costs	Manual labor accounted for up to 50% of transport costs
Risk of damage and loss	Goods were often damaged or stolen
Complicated intermodality	Transfer between transport modes was time-consuming and expensive

Introduction of the Container (Malcolm McLean, 1956)

First standardized container (corrugated steel sheet, length 8 and 10 feet, later 20 and 40 feet).
Rapid development of container ships, cranes, and terminals.
Significant reduction in costs, shortening of loading times from weeks to hours.
Possibility of “door-to-door” transport.

How Container Shipping Works? Main Process Steps

1. Booking

The shipper/person arranging transport (e.g., freight forwarder) books capacity with a shipping company for a specific route and time.
Specification: type(s) and number of containers, destination, schedule.

2. Container Delivery and Loading

Empty container is delivered to a warehouse/manufacturing facility.
Goods are professionally loaded, secured against movement (fixation, padding), container is sealed with a security seal.
At this stage, customs supervision may be required (export control).

3. Inland Transport to Port (Inland Haulage)

By truck or train to the container terminal.
First mile operation – may also include customs storage.

4. Port Operations and Loading onto Ship

Container is registered, weighed (VGM – Verified Gross Mass), undergoes export customs clearance.
Gantry cranes load containers onto the ship according to stowage plan (by destination, weight, nature of cargo).

5. Maritime Transport

Issuance of Bill of Lading (B/L) – key transport document, proof of ownership of goods and transport contract.
Tracking of ship position and shipment status (nowadays often online, in real time).

6. Unloading and Customs Clearance at Destination Port

Unloading of container, import customs procedure, possibility of physical inspection of goods.
Documentation check, correct declaration, payment of VAT and duty.

7. Inland Transport to Recipient (“last mile”)

After customs clearance, container is transported by truck/train to the destination.

8. Unloading and Return of Empty Container

After unloading, container is returned to depot, inspected, possibly repaired, prepared for next use.

Types of Shipping Containers – Overview, Dimensions, and Use

Type of Container	Standard Dimensions (L x W x H, mm)	Internal Volume (m³)	Use and Notes
Standard (Dry Van)	20′: 6,058 × 2,438 × 2,591	33	Dry, packaged goods, pallets
Standard 40′	40′: 12,192 × 2,438 × 2,591	67
High Cube	40′: 12,192 × 2,438 × 2,896	76	Light/bulky cargo, higher internal space
Open Top	20’/40′, no fixed roof	–	Engineering units, oversized goods
Flat Rack	20’/40′, no side walls/roof	–	Heavy machinery, ship engines, vehicles
Refrigerated (Reefer)	20’/40′ with cooling unit	28/67	Food, pharmaceuticals, chemicals
Tank (Tanktainer)	20′ with tank	21–26	Liquids, gases, food and industrial liquids
Ventilated	20’/40′ with ventilation openings	33/67	Coffee, cocoa, agricultural products
Platform	20’/40′, floor only	–	Extreme oversized shipments

Notes:

Dimensions and volumes may vary slightly depending on manufacturer and container age (source: DHL, EasyCargo, Wikipedia).
All containers must be certified according to CSC (Convention for Safe Containers).

FCL vs. LCL – Two Basic Shipping Strategies

Type of Transport	Description	Advantages	Disadvantages	Suitable for
FCL (Full Container Load)	One shipper has the entire container	Speed, safety, less handling	Payment for entire container even if not fully used	Larger volumes
LCL (Less than Container Load)	Shipments from multiple shippers in one container	Payment only for own volume/weight	Longer transport time (consolidation/deconsolidation), more handling	Small and medium shipments

Customs Processes, Documentation, and Legislation

Main Steps of Customs Clearance (source: HZ Containers):

Customs declaration – must be submitted by the carrier/forwarder before crossing EU borders; contains information about value, origin, and classification of goods.
Documentation verification – customs authority checks that all documents are correctly completed (B/L, invoice, goods list, certificate of origin, CMR transport documents, EORI number).
Possible request for additional documents – for sensitive or risky goods, physical inspection of the container may occur.
Calculation and payment of duty and VAT – according to TARIC code and invoiced value.
Transit documents – e.g., T1 for goods subject to duty in transit, BHT, ZAPP (in Germany).
Customs warehouses – possibility of temporary storage of goods without immediate customs clearance.
Sanctions – for incorrect information/violation of rules, delays, fines, or seizure of goods may occur.

Main Documents in Container Shipping:

Bill of Lading (B/L) – maritime waybill, proof of ownership and transport contract.
CMR – transport document for road transport under the CMR convention.
Certificate of Origin – necessary for some destinations and duty reductions.
Cargo Insurance – recommended especially for valuable/insured goods.
EORI number – identification of entity in contact with EU customs authority.

Intermodality, Rail and Air Container Transport

Intermodal transport = seamless use of multiple types of transport without unloading cargo from container.
Rail containers – used especially within the Eurasian corridor (Silk Road), efficient compromise between price and speed (20–30 days China–Europe).
Air transport of containers – only for special containers (e.g., ULD), suitable for urgent, valuable, or sensitive shipments.
Door-to-door, door-to-port, port-to-port – various options depending on client needs and destination.

Current Trends and Innovations in Container Shipping (source: hz-containers.com)

1. Digitalization and Shipment Tracking

Smart containers – equipped with GPS, temperature/humidity sensors, real-time data transmission.
Online tracking – ability to track container location and status from anywhere.
Port automation – robotic cranes, autonomous vehicles, paperless clearance.

2. Environmental Innovations

Alternative fuels – LNG, methanol, ammonia, biofuels.
Slow steaming – reduction of ship speed to save fuel and emissions.
Eco-friendly ships – new designs, hybrid drives, “green” ports.

3. Global Challenges and Supply Chain Resilience

Geopolitical risks – conflicts (e.g., Ukraine, Red Sea) force carriers to change routes, increase costs, and extend transport times.
Container surplus/shortage – pandemic and natural disasters caused fluctuations in storage and container availability.
Automation and digitalization – need to adapt to new technologies throughout the supply chain.

Economic and Global Significance of Container Shipping

Foundation of globalization – enables efficient international trade, relocation of production to cheaper countries.
Availability of goods – wide range of products from around the world for consumers and businesses.
Inventory optimization and cash flow – possibility of JIT production, reduction of inventory levels.
Job creation – in logistics, ports, transport, container manufacturing.
