In recent years, more and more batteries have been exported from China to other parts of the world. However, batteries are dangerous goods, and domestic and foreign customs have strict control over the export of batteries. Many customers do not know what information is required for battery export by sea, what documents to provide, and what processes to follow.

Classification of batteries (differentiated according to the International Maritime Dangerous Goods Code)
1. Batteries (wet, filled with acid) UN2794, Class 8 dangerous goods. The main products are lead-acid batteries. (The electrolyte is different)
2. Batteries (wet, with lye) UN2795, Class 8 dangerous goods. The main products are nickel-metal hydride batteries.
3. Storage battery (wet, filled with electrolyte, sealed) UN2800, Class 8 dangerous goods. The main products are sealed storage batteries.
This type of battery has a sealed (overflow-proof) design. The electrolyte is absorbed in the plate and the diaphragm within the battery and cannot flow. For this type of battery, UN2800 is applicable, and if it can pass the test of 238, it can be regarded as ordinary cargo. (Provide relevant test reports)
4. Lithium-ion battery Lithium-ion battery is generally a battery using lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and a non-aqueous electrolyte. Lithium batteries commonly used for UN34809 dangerous goods are widely used in new energy vehicles.
5. The equipment contains lithium electronic batteries or the lithium ion battery UN34819 class of dangerous goods assembled together, which are usually some electronic devices such as mobile phones and notebooks with batteries.
6. lithium alloy batteries, lithium metal batteries. The lithium metal battery is generally a battery using manganese dioxide as a positive electrode material, metallic lithium or an alloy metal thereof as a negative electrode material, and a non-aqueous electrolyte solution. UN3090, Class 9 Dangerous Goods
7. Lithium metal battery UN30919 dangerous goods installed in the equipment
8. Dry batteries, solid potassium hydroxide, dangerous goods, category 8, UN3028. Alkaline,
9. Ni-MH battery, type 9, UN3496.
10. Fuel cells are divided into many types according to different electrolytes and dangerous components. There are the following categories.
UN3473, category 3, UN3476, category 4.3, UN3477, category 8, UN3478, category 2.1 and UN34792.1;
Fuel cell powered vehicles or fuel cell powered engines, dangerous goods, category 9, UN3166.
11. Sodium batteries, dangerous goods, category 4.3, UN3292.
12. Battery-powered vehicles or battery-powered equipment. UN31719 dangerous goods. Commonly used are electric cars and battery cars.

Special regulations affecting battery hazard classification
“Special regulations” not only cover the scope of application of the UN number, but also include information on exemption conditions, special packaging requirements, and special transportation requirements. The results of certain special regulations can directly determine the classification of transportation risks and related requirements of battery products (including government supervision content, enterprise transportation management of products, etc.).
1. Special Provisions 230
For lithium batteries (groups) and lithium batteries (groups) in the equipment (mainly referring to UN3090, UN3091, UN3480 and UN3481), they can only be transported if they meet the requirements of special regulation 230. The specific requirements are summarized as follows:
1) The lithium battery or lithium battery must pass the 8 tests (height simulation, temperature test, vibration, shock, external short circuit, etc.) in Part 38.3 of the United Nations TDG Manual of Tests and Standards (38.3 test);
2) Each battery and battery pack is equipped with a safety exhaust device, or is designed to prevent force rupture under the conditions of ordinary accidents during transportation;
3) Each battery and battery pack are equipped with effective devices to prevent external short circuits;
4) Each battery pack containing multiple parallel batteries or battery series is equipped with effective devices (such as diodes, fuses, etc.) necessary to prevent danger caused by reverse current
5) Manufacturers of batteries and battery packs must have a high-quality management program to ensure it.
2. Special regulations 304
When classifying the hazards of alkaline batteries (including UN2795, UN3028 and UN2797), special attention should be paid to UN3028. According to the requirements of special regulation 304, UN3028 is only applicable to batteries that contain dry potassium hydroxide during transportation and are not activated. Before use, an appropriate amount of water must be added to a single electrode to activate it. Therefore, for such batteries, different UN numbers will be applied depending on whether they are activated during transportation, as shown in the figure.

Classification of alkaline batteries (including potassium hydroxide)
3. special regulations 328
All fuel cell cartridges, including fuel cell cartridges in equipment or fuel cell cartridges installed with the equipment, must meet the relevant requirements of special regulation 328, as summarized below:
1) It must be designed and manufactured to prevent fuel leakage under normal transportation conditions;
2) The design type of fuel cell cartridges using liquid as fuel must pass an internal pressure test of 100kPa (measurement) without leakage;
3) With the exception of fuel cell cartridges that store hydrogen in metal hydrides in accordance with special requirements 339, each fuel cell cartridge design type must demonstrate that it can pass a 1.2-meter drop test on a hard surface in the direction of destroying its containment system, and No loss of contents.
Therefore, the fuel cell must first meet the above basic requirements before transportation, and at the same time combine the type of fuel (flammable liquid, flammable gas or corrosive substance, etc.), and refer to and meet the corresponding remaining special regulations before carrying out such batteries. transport.
In addition, special regulation 117 states that UN3496 is only applicable to marine transportation; special regulation 295 states that when the battery is transported by sea, the pallet is appropriately marked and marked, and the battery pack does not need to be marked and marked separately. And description.

Battery shipping requirements
1. The battery must pass the UN38.3 test requirements and the 1.2-meter drop packaging test.
2. The outer packaging must be affixed with a dangerous goods label and marked with the UN number.
3. It is designed to prevent bursting under normal transportation conditions, and is equipped with effective measures to prevent external short circuits and to protect exposed electrodes.
4. In a sturdy outer packaging, the battery should be protected against short circuits, and contact with conductive materials that can cause short circuits should be prevented in the same packaging.
5. Additional requirements for batteries installed in the equipment for transportation:
① The equipment should be fixed to prevent it from moving inside the packaging, and the packaging method should be prevented from accidentally starting during transportation.
② The outer packaging should be waterproof, or be waterproofed by using an inner lining (such as a plastic bag), unless the structural characteristics of the device itself are already waterproof.
6. Lithium batteries should be loaded in trays to avoid strong vibration during the handling process. The vertical and horizontal sides of the trays should be protected by corner protectors.
7. The lithium battery loading container must be reinforced. The reinforcement method and strength should meet the requirements of the importing country.
For example, in the United States, there are the American Railroad Association, the American Dangerous Goods Association, the North American Explosives Agency, the Federal Motor Transport Safety Administration, the U.S. Coast Guard, the United States Department of Transportation of Class 9 Dangerous Goods Containers, and the "American Maritime Dangerous Goods Transportation Regulations." "There are relevant regulations). If the shipper negligently reinforces or improperly reinforces the container, the container will be detained at the port of destination, and high costs such as terminal operation fees, storage fees, container removal fees, and re-reinforcement will occur.

Booking of battery products must be provided like other dangerous goods
