Lithium batteries belong to Class 9 hazardous materials and require Class 2 packaging.

Firstly, if you are a manufacturer, you need to go to the commodity inspection bureau to file a battery record.

The dangerous goods certificate you mentioned requires the cardboard box factory to first issue a dangerous goods packaging performance result sheet. You can take this sheet and the classification identification certificate of your battery (which is also done at the inspection bureau) to the inspection bureau to exchange for the dangerous goods certificate.

The information required for outbound inspection is similar to that of ordinary goods, except for an additional record. However, there may be slight deviations in the requirements of local inspection bureaus. We suggest that you call the inspection bureaus to inquire.

In addition, both sea and air transportation require a UN38.3 report, and sea transportation also requires an MSDS.

The transportation methods for lithium-ion batteries include air transportation, water transportation, and land transportation. Therefore, the most commonly used special transportation and ocean transportation are mainly discussed.

Due to lithium being a metal that is particularly prone to chemical reactions, it is prone to elongation and combustion. Improper handling of lithium battery packaging and transportation can lead to combustion and explosion, and accidents can also occur from time to time. The accidents caused by non-standard behaviors in its packaging and transportation are receiving increasing attention. Multiple international institutions have issued multiple regulations, and management agencies have become increasingly strict. They have raised operational requirements and continuously revised regulations and rules (such as IATA's modification of regulations for lithium battery transportation every two years)

Management scope of the management organization

United Nations (UN) worldwide, various forms of transportation

International Civil Aviation Organization (ICAO) worldwide, special equipment

IATA World Wide, Special Equipment

International Maritime Organization (IMO) worldwide, maritime transport

United States Department of Transportation (USDOT), various forms of transportation in the United States

European Land Transport Agreement (ADR) Europe, land transport

1) Lithium batteries and lithium battery packs are classified as Class 9 dangerous goods

2) All lithium batteries (groups) must pass the UN38.3 test

3) Exceptional clauses have been provided for the transportation of lithium batteries for some Class 9 hazardous materials

4) Strict restrictions have been imposed on the transportation of samples

5) Limitations on daily lithium batteries carried by passengers

6) All defective or damaged batteries are prohibited from transportation restrictions

The transportation of lithium batteries first requires the provision of corresponding UN numbers. Lithium batteries are classified as Class 9 miscellaneous hazardous materials as follows:

UN3090, Lithium metal batteries

UN3480, Lithium ion batteries

UN3091, Lithium metal batteries installed in equipment

UN3091, Lithium metal batteries packaged with equipment

UN3481, Lithium ion batteries installed in equipment

UN3481, Lithium ion batteries packaged with equipment

Lithium metal battery: A disposable battery typically composed of lithium metal or a mixture of lithium as the anode.

Lithium ion batteries: Lithium ion batteries (abbreviated as LiionBatteries) are batteries made by using a compound of lithium as the positive electrode, a carbon material that can embed and remove lithium ions instead of pure lithium as the negative electrode, and a mixed electrolyte as the electrolyte. It is a reusable battery commonly used in the consumer electronics industry.

Batteries produced from different lithium-ion battery cell materials can be divided into polymer batteries, square batteries, and cylindrical batteries (usually 18650 cells).

The technical definitions of batteries and battery cells mentioned in the United Nations testing and standards manual are as follows:

A battery refers to two or more battery cells connected together by an electrical circuit and equipped with necessary devices for use, such as a casing, electrode terminals, markings, and protective devices.

Single cell batteries are considered as "battery cells" (treated as battery cells during UN38.3 testing). A battery cell is a single, enclosed electrochemical device consisting of a positive electrode and a negative electrode, with a potential difference between the two electrodes. Regardless of whether they are referred to as "batteries" or "single cell batteries" outside of these rules and United Nations testing standards and manuals, they are referred to as "battery cells" rather than batteries in our rules and United Nations testing standards and manuals. In DGR, single cell batteries should be considered as battery cells rather than batteries for limitation.

Generally speaking, the most commonly used lithium-ion batteries are button batteries, etc;

Lithium batteries in laptops and power tools are composed of several (3-9) battery cells in series and parallel; The power lithium battery pack is composed of dozens to hundreds of battery cells in series and parallel, and is equipped with a protective circuit device to provide power for it;

On the other hand, mobile phones and MP3 players basically use a single lithium-ion battery cell or a single lithium-polymer battery cell, combined with a protective circuit device to form a battery.

The new lithium battery measurement standard is: rated watt hour (Wh). If the nominal voltage (V) and nominal capacity (Ah) of the battery are known, the value of rated watt hour can be calculated: Wh=VxAh Ampere multiplied by the nominal voltage equals the nominal voltage and nominal capacity of the watt hour. This indicator is required to be marked on the battery.

Lithium battery transportation packaging

1. Without considering exceptions, these batteries must be transported in accordance with the restrictions in the rules (packaging instructions applicable to DGR4.2). They must be packed in UN specification packaging according to the applicable packaging instructions, and the corresponding number must be fully displayed on the packaging.

2. Packaging that meets the requirements, except for those marked with the applicable correct transport specific name and UN number,

Class 9 hazardous material labels

Class 9 hazardous material labels

It is also necessary to affix a Class 9 hazard label.

3. The shipper must fill out the dangerous goods declaration form; Provide corresponding dangerous goods certificates;
