Combined with the relevant policies of the General Administration of Customs and the International Maritime Organization on the export and international transportation of lithium batteries, we will give you a detailed interpretation of “how to label the export of lithium batteries” and “How to comply with the international transportation of lithium batteries”. You can read it carefully: (Key points)
1. The inspection and supervision of lithium batteries and their lithium battery products are mainly based on the United Nations “Model Regulations on the Transport of Dangerous Goods”, the United Nations “Manual of Tests and Standards for the Transport of Dangerous Goods”, the International Maritime Organization “Rules for the International Carriage of Dangerous Goods by Sea”, the International Civil Aviation Organization “Technical Rules for the Safe Transport of Dangerous Goods by Air” and “Export Dangerous Goods Packaging Inspection Regulations” (SN/T0370.1-2009), (SN/T0370.2-2009), (SN/T0370.3-2012) and other laws and regulations;
2. The international logistics and transportation of lithium batteries for import and export mainly refers to the “Rules for the International Carriage of Dangerous Goods by Sea” (hereinafter referred to as the “IMDG Rules”) of the International Maritime Organization.The “IMDG Rules” are updated internationally every two years. The current version is Version 40-20. This version will be implemented voluntarily from January 1, 2021 and will be mandatory from June 1, 2022. There are detailed definitions and descriptions of lithium battery products in the rules. In order to facilitate understanding, we will organize them into the following table for everyone:

Detail Tests of Certifications:
The rules also require that exported lithium batteries must pass the UN38.3 test and provide a summary of the test:
- Each battery and battery pack must be equipped with a safety exhaust device. If an ordinary accident occurs, it must be designed to prevent damage by force.
- Each battery and battery pack must be equipped with an effective device to prevent external short circuits
- Each battery pack that contains multiple parallel batteries or battery series must be equipped with effective devices (such as diodes, fuses, etc.) required to prevent the danger caused by reverse currents.
- Manufacturers of batteries and battery packs must establish a good quality management system and so on.
UN38.3: Lithium Polymer Battery Height Simulation Test
- Test lithium polymer batteries and lithium polymer batteries should be stored at an ambient temperature of 11.6kPa or lower for at least 6 hours at an ambient temperature of 20±5℃.
- If lithium polymer and lithium polymer batteries are not weightless, do not leak, do not exhaust, do not disassemble, do not break, and do not catch fire,
- And the open circuit voltage of each test cell or battery after the test is not lower than 90% of the voltage before this process.
- Energy-related requirements do not apply to testing batteries and battery packs in a fully discharged state.
UN38.3: Lithium Polymer Battery Temperature Test
- Test lithium polymer batteries and lithium polymer batteries to store at a test temperature of -72±5℃ for at least 6 hours,
- Then store at a test temperature of -40±2℃ for at least 6 hours.
- The maximum time interval between testing extreme temperatures is 30 minutes.
- This process should be repeated ten times, and then all test batteries and battery packs should be stored at ambient temperature for 24 hours.
- Lithium polymer batteries and polymer lithium batteries have no weightlessness, no leakage, no exhaust, no disassembly, no cracking, and no fire, and the open circuit voltage of each test cell or battery after the test is not lower than 90% of its voltage immediately before this process. Voltage-related requirements do not apply to testing batteries and battery packs in a fully discharged state.
UN38.3: Lithium Polymer Battery Oscillation Test
- The test lithium polymer battery and the lithium polymer battery are firmly fixed on the platform of the vibrator, which will not deform the battery, thereby faithfully transmitting vibration.The vibration should be a sinusoidal waveform, logarithmic scanning between 7 Hz and 200 Hz, and return to 7 Hz within 15 minutes.
- For each of the three mounting positions perpendicular to each other of the battery, the cycle should be repeated 12 times for a total of 3 hours.One of the vibration directions must be perpendicular to the terminal surface.
- Batteries and battery packs (batteries and small batteries) with a total mass of not more than 12 kg
- It should be different from the logarithmic wavelength scanning of battery packs (large lithium batteries) with a total mass of more than 12 kilograms.
- For lithium batteries and small lithium polymer batteries:Starting at 7 Hz, maintain a peak acceleration of 1 gn until it reaches 18 Hz. The amplitude is then maintained at 0.8mm (total offset 1.6 mm) and the frequency increases until a peak acceleration of 8 gn (approximately 50 Hz) occurs. Then maintain the peak acceleration of 8 gn until the frequency increases to 200Hz.
UN38.3: Lithium Polymer Battery Crash Test
- The test lithium polymer battery and lithium polymer battery should be fixed to the testing machine using a rigid bracket, which will support all mounting surfaces of each test battery.
- Each lithium polymer battery should withstand a semi-sinusoidal impact with a peak acceleration of 150 gn and a pulse duration of 6 milliseconds.Alternatively, a large battery may be subjected to a semi-sinusoidal shock with a peak acceleration of 50 gn and a pulse duration of 11 milliseconds.
- Each battery should withstand the semi-sinusoidal impact of peak acceleration according to the mass of the lithium battery.
- The pulse duration of a small lithium polymer battery should be 6 milliseconds, and the pulse duration of a large lithium polymer battery should be 11 milliseconds.
- The battery cell and battery pack have no weightlessness, no leakage, no exhaust, no disassembly, no rupture, and no fire, and the open circuit voltage of each test cell or battery pack after the test is not lower than 90% of its voltage before this process.
- Voltage-related requirements do not apply to testing batteries and battery packs in a fully discharged state.
