1. What are Containerizable Goods?
Containerizable Goods refer to cargo suitable for containerized sea freight. Not all goods are suitable for containerization; choosing the correct shipping method is the first step in cost control.
2. Classification by Suitability
🟢 High Suitability (Strongly Recommend Containerized Sea Freight)
| Cargo Type | Examples | Characteristics |
|---|---|---|
| Manufactured Goods | Machinery & Equipment, Hardware Tools, Building Materials | Resistant to crushing, standardized packaging |
| Consumer Goods | Household Items, Clothing, Shoes & Hats, Toys | Moderate volume, high value |
| Electronic Products | Appliances, Mobile Phones, Computers, Accessories | High value, requires moisture and shock protection |
| Food & Beverage | Canned goods, Bottled Water, Condiments, Frozen items (Reefer) | Uniform packaging, stackable |
| Chemicals (Non-Hazardous) | Plastic Granules, Resin, Detergents | Sealed packaging, non-toxic, non-hazardous |
🟡 Conditional Suitability (Special Handling Required)
| Cargo Type | Notes | Recommended Shipping Method |
|---|---|---|
| Oversized Cargo (OOG) | Exceeds container dimensions, requires open-top or flat rack | Special Containers |
| Heavy Cargo (Single piece >3 tons) | Exceeds floor load capacity | Flat rack or charter vessel |
| Dangerous Goods (DG) | Requires MSDS, Dangerous Goods Packaging Certificate, DG declaration | Operate per IMDG Code |
| Refrigerated/Frozen Cargo | Requires full temperature control, container requires power connection | Reefer Container |
| Live Animals | Requires special ventilation and feeding conditions | Special animal container or airfreight charter |
🔴 Inappropriate (Not Recommended for Containerized Sea Freight)
| Cargo Type | Reason | Recommended Shipping Method |
|---|---|---|
| Bulk Commodities (Grain, Ore, Coal) | Low container loading/unloading efficiency, high cost | Bulk Carrier (Charter Vessel) |
| Bulk Steel (Steel coils, billets, ingots) | Concentrated weight, prone to damaging container floor | Bulk carrier or flat rack |
| Liquids (Large quantities) | Requires tank containers, higher cost | ISO Tank or bulk carrier |
| Oversized Items (Exceeding container dimensions significantly) | Cannot fit standard container | Project Cargo |
3. Classification by Cargo Nature
General Cargo
The most commonly shipped cargo type, suitable for container sea freight as long as packaging meets requirements. Includes:
Dangerous Goods (DG)
Dangerous goods are divided into 9 classes and must strictly adhere to IMDG Code (International Maritime Dangerous Goods Code) operations:
| Class | Category | Examples |
|---|---|---|
| Class 1 | Explosives | Fireworks, Ammunition |
| Class 2 | Gases | Lighters, Compressed Gases |
| Class 3 | Flammable Liquids | Paint, Solvents, Alcohol |
| Class 4 | Flammable Solids | Sulfur, Matches, Activated Carbon |
| Class 5 | Oxidizers/Organic Peroxides | Hydrogen Peroxide, Bleach |
| Class 6 | Toxic Substances | Pesticides, Chemical Intermediates |
| Class 7 | Radioactive Material | Medical Radioactive Sources |
| Class 8 | Corrosives | Sulfuric Acid, Sodium Hydroxide |
| Class 9 | Miscellaneous Dangerous Goods | Lithium Batteries, Magnets, Life-saving Equipment |
Requirements for DG transport: MSDS (Safety Data Sheet), Dangerous Goods Packaging Certificate, UN marking on packaging, DG Declaration, DG labels.
4. Heavy vs Light Cargo (Revenue Ton Calculation)
In LCL sea freight, freight is calculated based on Revenue Ton (RT)—taking the larger of actual weight and volumetric weight.
Revenue Ton Conversion Formula
| Shipping Mode | Conversion Standard |
|---|---|
| LCL Sea Freight | 1 CBM = 1,000 kg (1 ton) |
| Air Freight | 1 CBM = 167 kg |
| Courier | 1 CBM = 200 kg (certain routes) |
Calculation Example
Cargo lot: Volume 2.5 CBM, Weight 1,800 kg
LCL Sea Freight charging:
Volumetric charge = 2.5 RT
Weight charge = 1,800 ÷ 1,000 = 1.8 RT
Higher value charged = 2.5 RT (charged by volume)
LCL Sea Freight charging (another example):
Volume 1.2 CBM, Weight 2,100 kg
Volumetric charge = 1.2 RT
Weight charge = 2,100 ÷ 1,000 = 2.1 RT
Higher value charged = 2.1 RT (charged by weight)
Impact on Charging
| Cargo Type | Volume/Weight Ratio | Pricing Method | Suggestion |
|---|---|---|---|
| Heavy Cargo (Steel/Machinery) | Volume Weight | Charged by Weight | Suitable for Sea Freight (Volume-charged cargo offers better value) |
| Light/Bulky Cargo (Cotton/Plastic Products) | Volume > Weight | Charged by Volume | Optimizing packaging to reduce volume can save money. |
| Balanced Cargo | Volume ≈ Weight | Charged by higher actual | Standardized shipping |
5. Impact of Packaging on Containerizability
Packaging directly affects whether cargo is "containerizable":
| Packaging Type | Suitable Cargo | Notes |
|---|---|---|
| Carton | Light industrial goods, consumer goods | Moisture protection, stacking layers |
| Wooden Case | Heavy goods, precision equipment | Requires fumigation treatment (for exports to Europe and other regions) |
| Pallet | Standardized goods | Improves loading/unloading efficiency, reduces damage. |
| Metal/Plastic Drum | Liquids, chemicals | Requires UN certification (for dangerous goods). |
| Bundling | Steel, profiles | Requires reinforcement. |
