What are the main classifications of goods in international freight?
In the field of international logistics, there are many types of goods. According to their nature and transportation requirements, they are usually divided into three categories: general cargo, special cargo and dangerous goods. These classifications not only determine the choice of transportation mode, but also affect the arrangements of customs declaration, packaging, insurance and other links.
Ordinary goods refer to mass commodities that do not have special transportation requirements, such as clothing, toys, electronic accessories, furniture, etc., which account for a considerable proportion of international trade. Special goods refer to goods with special requirements in terms of volume, weight, temperature or other conditions, such as cold chain products, large equipment, precision instruments, fragile goods, etc. Dangerous goods refer to goods with potential hazards such as explosiveness, flammability, corrosiveness or radioactivity, such as lithium batteries, paints, chemical raw materials, etc.
The purpose of clear classification is to ensure compliance, safety, responsibility division and cost control during transportation, and to ensure that goods are not rejected, delayed or incur unexpected liabilities during cross-border transportation.
Characteristics and identification methods of ordinary goods
Ordinary goods usually have no dangerous properties and are not difficult to transport. They can be freely transported by sea, air, rail, etc. without the need for additional declarations or special permits. They have standardized packaging and simple customs clearance procedures, making them the most common and convenient type of goods in trade. They account for more than 60% of international trade volume.
Common categories of general cargo:
- Textiles (clothing, home textiles)
- Daily necessities (tableware, toys)
- Battery-free electronic accessories (non-smart sockets, traditional lamps)
- Non-metallic building materials (ceramic tiles, plastic pipes)
The method of identifying general cargo is relatively simple, and generally has the following characteristics:
- No special environment such as constant temperature and humidity is required
- Does not contain special ingredients such as batteries, chemicals, liquids, etc.
- International transportation is possible without special declarations
- No additional certificates are required for customs clearance (such as MSDS, dangerous goods certificates)
- Can be transported by ordinary freight forwarders, without professional dangerous goods handling qualifications
For example, a batch of goods shipped from China to France in 2025 was shipped by sea in a standard 20ft container. The goods were mainly cotton T-shirts, and there was no special operation throughout the process. This type of goods has high transportation efficiency and relatively low prices, and is the first choice for primary traders.
Definition and transportation requirements of special goods
Although special goods are not dangerous goods, they have “non-standard” characteristics in terms of size, weight, physical properties or environmental requirements, so special packaging, loading and unloading and transportation measures are required. Mistakenly treating special goods as ordinary goods is likely to result in rejection, delay or additional costs.
Special goods mainly include the following categories:
Oversized/overweight goods: such as construction machinery and large equipment, which require hoisting or special pallets. Special flatbed trucks/frame boxes are required, and road permits must be declared before transportation (such as the EU’s ESC certificate)
Cold chain products: such as fresh food, vaccines, and some cosmetics must be kept at low temperatures during transportation. Cold chain transportation requires real-time temperature monitoring (such as 2-8℃ constant temperature containers), and some require health quarantine certificates
High-value/precision equipment: such as instruments and meters, semiconductor chips, medical imaging equipment, etc., require special cushioning packaging and shockproof treatment.
Fragile items: Glass products, ceramics, etc. require wooden boxes for reinforcement and clear markings
Battery-containing products: Electronic devices with built-in lithium batteries are usually classified as special goods or “marginal items” of dangerous goods. They need to be distinguished between UN3480 (batteries transported separately) and UN3090 (equipment with batteries). Some countries require battery power declaration.
For such goods, the owner should explain the specific characteristics to the logistics company before shipment and prepare corresponding supporting documents, such as dimension drawings, temperature control requirements, and proof of declared value, to avoid being misjudged as ordinary goods due to incomplete information.
Risk warning: A company once shipped electric scooters containing lithium batteries as ordinary goods. After arriving at the destination port, it was fined €5,000 for not declaring the batteries and returned the goods.
Identification and declaration standards of dangerous goods
Dangerous goods are the most strictly regulated type of goods in international freight. According to the classification standards of the International Civil Aviation Organization (ICAO), the International Maritime Organization (IMO) and other organizations, dangerous goods are divided into 9 categories, including explosives, compressed gases, flammable liquids, toxic substances, radioactive substances, etc.
| Classification | Typical Goods | Key Transportation Requirements |
|---|---|---|
| Class 1 | Fireworks, Detonators | Only transported by specialized dangerous goods ships, require isolated storage |
| Class 3 | Gasoline, Paint | Prohibited for air transportation, require flammable labels and leak-proof packaging |
| Class 8 | Sulfuric Acid, Sodium Hydroxide | Containers need anti-corrosion linings, MSDS required for declaration |
| Class 9 | Lithium Batteries, Automotive Airbags | Need to pass UN38.3 test, comply with IATA DGR standards for air transportation |
The key to identifying dangerous goods is to understand their UN numbers and MSDS (Material Safety Data Sheets). Several common examples of dangerous goods include:
- Lithium batteries (UN3480 / UN3481)
- Foaming agents, paints (flammable liquids)
- Chemical reagents (corrosive)
- Disinfectant tablets, pesticides (toxic substances)
- Compressed gas cylinders (gas)
Transporting dangerous goods requires freight forwarding companies or carriers with specific qualifications, and at the same time, they must strictly comply with international regulations in packaging, labeling, declaration, and shipping agreements. It is illegal to ship dangerous goods without declaring them. At the least, the goods will be detained, and at the worst, legal liability will be borne.
Therefore, when exporting products involving potentially hazardous ingredients, companies must verify the product ingredients in advance and contact professional freight forwarders to conduct classification and identification and assist in declaration.
How to judge whether the goods are ordinary goods, special goods, or dangerous goods
Many companies have a vague understanding of the transportation attributes of new products. The following are practical process suggestions for identifying the type of goods:
Check the product manual or MSDS: clarify whether the product contains dangerous ingredients or special transportation requirements;
Confirm with the manufacturer: the manufacturer knows the product structure best and can provide key information such as battery model and material description;
Consult professional freight forwarders or third-party testing agencies: experienced logistics companies can assist in judging and recommend compliance paths;
Simulated customs declaration/shipping attempts: Some platforms provide a forecasting system to preliminarily determine whether it is a special category;
Reference to UN number/international classification table: especially chemical products, the properties can be compared through the UN List;
The difference between transporting ordinary goods, special goods, and dangerous goods from China
| Feature | General Cargo | Special Cargo | Dangerous Cargo |
| Fundamental Differences | Standard goods | Specific handling | High-risk, strictly regulated |
| Packaging and Handling Requirements | Standardized | Specialized | Highly regulated |
| Storage and Transportation Modes | Flexible | Specific | Highly strict |
| Risk Management Strategies | Preventing damage and loss | Maintaining product quality | Reducing safety and security risks |
| Cost Implications | Lower costs | Higher costs due to specialized needs | Highest costs due to extensive regulations and precautions |
In international freight, correctly identifying the type of goods is not only related to transportation efficiency, but also to the compliance and reputation of the company. Incorrect classification or declaration may lead to a series of serious consequences, including:
- Delay or return of goods
- Rejection by the carrier or destination country
- High detention, storage or fine fees
- Legal proceedings and even criminal liability
Therefore, it is recommended that export companies or e-commerce sellers establish a standardized cargo attribute identification and declaration process when processing international orders, cooperate with logistics service providers with professional experience, and update product transportation compliance information in a timely manner to prevent in advance, control during the process, and check after the event.
