Shipping rules for lithium batteries in international trade

The United Nations 'Model Regulations for Recommendations on the Transport of Dangerous Goods' (TDG) regulations issued in July 2017. It is a legal document specially formulated by the United Nations in the 1950s to regulate the international transportation of dangerous goods, and it is also a basic document for the global transportation of dangerous goods. Its technical revision will have a profound impact on the shipping and air transportation of dangerous goods. Important amendments have been made to two parts of the TDG regulations regarding lithium batteries: 　　 (1) 14 UN numbers have been added to categories 2 to 9 dangerous goods, of which UN3536 is designated for installation in cargo installations in category 9 dangerous goods Lithium ion or lithium metal battery pack inside. This type of battery must be firmly fixed in the internal structure of the cargo transportation device, and there is no need to affix a transportation mark or label on the surface of the battery, but it needs to be affixed with the UN number and hanging signs on both sides.　　 (2) In the 'List of Dangerous GoodsIn Special Provision 388, the UN numbers of various types of power vehicles and equipment containing lithium batteries and sodium batteries are clearly defined: lithium metal batteries, lithium ion batteries, sodium batteries, etc., which are driven by flammable gas or flammable liquid Hybrid vehicles (UN3166), lithium metal batteries, lithium ion batteries, sodium batteries, etc., pure electric vehicles driven by flammable gas or flammable liquids (UN3171), lithium metal batteries (UN3091) installed in equipment, and equipment installed Lithium-ion battery in the (UN3481).　　 In addition, IATA (International Air Transport Association) has revised the 59th edition of the dangerous goods transportation regulations, and recently released the revised version, many of which also involve air transportation of lithium batteries. It is understood that the new rules will be implemented from January 2018. The main changes are as follows: 　　 (1) The isolation rules for lithium batteries have been added: Lithium ion batteries (UN3480, PI965SectionIAorIB) and lithium metal batteries (UN3090, PI968SectionIAorIB) and including explosives (Class1), ammunition (Division1.4S), and easy Combustible gas (Division2.1), flammable liquid (Class3), flammable solid or self-reactive substances or solid desensitization explosives (Division4.1), oxidizer (Division5.1) are packed in the same outer packaging.　　 (2) The total number of portable electronic devices carried by passengers or crew members shall not exceed 15, and the number of spare batteries shall not exceed 20. If the number exceeds the above number, the airline must obtain approval. (3) It is stipulated that the height of the UN code number in the lithium battery mark (Lithiumbatterymark) shall not be less than 12mm　　. In addition, the International Maritime Organization's 'International Maritime Dangerous Goods Code' (IMDGCODE) version 38-16 will also be released from January 2018 Enforcement began in China. Among them, P910 packaging guidelines have been added for lithium batteries that are SP310 low-yield, have an annual output of less than 100, and have not passed the UN38.3 test of the 'Test and Standard Manual' and are transported for testing. In order to ensure the transportation safety of lithium-ion batteries, battery companies must: 　　 (1) Pay attention to the new requirements of the new United Nations regulations on lithium batteries, especially the new definition of the UN number of lithium batteries and the 'damaged/defective' lithium battery Transportation requirements.　　 (2) Continue to pay attention to the introduction time of the international maritime dangerous regulations and international air transportation dangerous regulations to the new United Nations regulations, and make adjustments to the transportation packaging and documentation of lithium batteries as soon as possible.　　 (3) Strengthen the contact with inspection and quarantine departments and cargo transportation agencies, understand the implementation rules of the new United Nations regulations by various departments, and ensure the smooth consignment of exported lithium batteries.　　 At present, most of the industry regulations on lithium battery transportation are for air and sea transportation, and there are very few regulations for land transportation of lithium batteries. But in fact, there are not many fire accidents in the land transportation of lithium-ion batteries, which is shocking. It is understood that in 2016, there were many lithium battery transportation accidents in China alone. Although there were no casualties, the losses and impacts should not be ignored. In recent years, fire accidents in lithium-ion battery manufacturers have occurred from time to time, and higher-level authorities and industry associations have begun to increase the management of lithium battery companies in terms of safety production. For example, the China Chemical and Physical Power Supply Industry Association has begun to formulate lithium batteries. Industry group regulations for safe production. However, this is not enough. In addition to the production link, the transportation link also needs attention. Due to the particularity of lithium batteries, it is more necessary to have land transportation specifications based on its own technical characteristics, especially in the transportation of used lithium-ion batteries. This will not only ensure transportation safety, but will also help promote the recycling of used power lithium-ion batteries. use. With the development of new energy vehicles, power batteries are being driven, and the scale of lithium-ion batteries will be larger. The industry must consider the safe transportation of lithium-ion batteries in advance. The safety regulations for land transportation also need to be formulated to ensure that lithium-ion batteries are The security of the link.
