6.1 General requirements
6.1.1 Each container shall be marked with a durability mark in accordance with 5.2. 6.1.2 The export dangerous goods transport packaging shall have a reasonable structure, good protective performance, and comply with the specifications of the "Model Regulations" and the "International Maritime Dangerous Goods Code" (hereinafter referred to as the "International Dangerous Goods Code") for the corresponding transport mode. Its design mode, process and material shall be adapted to the characteristics of dangerous goods in the corresponding transport form, suitable for stowage, and convenient for safe transportation. Loading, unloading and transportation should be able to withstand the risks under normal transportation conditions. 6.1.3 Dangerous goods should be packed in good quality containers that are strong enough to withstand the shocks and loads normally encountered during transportation, including transshipment between transport units and between transport units and warehouses, as well as removal of pallets or outer packaging for subsequent manual or mechanical operations. The structure and closure of the container should prevent any loss of contents that may be caused by vibration under normal transportation conditions or by changes in temperature, humidity or pressure (such as those caused by changes in altitude) when preparing for transportation. No hazardous residues should adhere to the outside of the container during transportation. These requirements apply to new, reused, repaired or modified containers. 6.1.4 When using plastic barrels (cans), plastic composite containers for the first time Containers and containers with coatings must be directly loaded with dangerous goods to be transported and stored for more than 6 months for compatibility testing in accordance with GB/T22410 before testing. 6.1.5 The various parts of the container that are in direct contact with dangerous goods: a) should not be affected by dangerous goods or have their strength significantly weakened by dangerous goods; b) should not cause dangerous effects in the package, such as causing dangerous goods to react or react with dangerous goods. If necessary, these parts should have appropriate inner coatings or be properly treated. 6.1.6 If the container contains liquid, sufficient unfilled space should be left to ensure that the container does not leak or permanently deform due to expansion of the liquid caused by temperature changes that may occur during transportation. Unless there are specific requirements, liquids must not fill the container at a temperature of 55°C.
6.1.7 The inner packaging should be placed in the outer packaging in such a way that it will not break, be punctured or its contents will not leak into the outer packaging under normal transport conditions. For those inner packagings that are easy to break or be punctured, such as those made of glass, ceramics, stoneware or certain plastics, they should be fixed in the outer packaging with appropriate cushioning materials. If the contents leak, the protective properties of the cushioning material or the outer packaging should not be significantly damaged. a) The cushioning and absorption materials should be inert and compatible with the properties of the contents; b) The properties and thickness of the outer packaging material should ensure that no heat is generated during transportation due to friction that may seriously change the chemical stability of the contents.
6.1.8 Dangerous goods should not be placed in the same outer packaging or in large packagings with other dangerous goods if they can react dangerously with each other and cause:
combustion or release of large amounts of heat;
release of flammable, toxic or asphyxiating gases; b)
production of corrosive substances;
d) production of unstable substances.
6.1.9 The closure of containers containing moist or diluted substances should be such that the percentage of liquid (such as water, solvents or phlegmatizers) does not drop below the specified limits during transportation. 6.1.10 All new, remanufactured and reused containers should be able to pass the tests specified in SN/T0370:2. Before filling and handing over for transportation, each container should be inspected in accordance with SN/T0370.3 to ensure that there is no corrosion, contamination or other damage. When a container shows signs of reduced strength compared with the approved design type, it should not be used again or should be refurbished to enable it to pass the design type test. 6.1.11 Liquids should be packed in containers that have an appropriate tolerance to the internal pressure that may be generated under normal transport conditions. If the package may generate pressure due to the release of gas from the contents (due to temperature increase or other reasons), a vent may be installed on the container (approval from the aviation transport authority must be obtained for air transport). The released gas should not cause danger due to its toxicity, flammability and emission volume. The vent should be designed to ensure that under normal transport conditions, when the container is in the transport state, there will be no liquid leakage and foreign matter penetration. 6.1.12 Containers marked with the hydraulic test pressure specified in 5.2.2d) may only be loaded with liquids with the following vapor pressures: a) The total gauge pressure in the container (i.e. the vapor pressure of the loaded substance plus the partial pressure of air or other inert gas, minus 100 kPa) determined based on a loading temperature of 15°C and the maximum filling degree specified in 6.16 shall not exceed two-thirds of the marked test pressure at 55°C; b) At 50°C, it shall be less than four-sevenths of the sum of the marked test pressure plus 100 kPa; at 55°C, it shall be less than one-third of the sum of the marked test pressure plus 100 kPa. c) 6.1.13 If a considerable internal pressure gradually builds up in the packaging of dangerous goods, the packaging shall be constructed to prevent the container from rupturing due to the increase in internal pressure caused by internal pressure or external factors. 6.1.14 According to the characteristics of the dangerous goods, the packaging shall be firmly sealed, liquid-tight or airtight. 6.1.15 Valves for filling sprayers, gas and liquefied gas containers should be equipped with protective devices. Each container intended to contain liquids should successfully pass the appropriate sealing test under the following conditions and be able to reach the appropriate test level specified in 6.1.16
SN/T0370.2: before being used for transportation for the first time;
before any container is used for transportation again after modification or arrangement; b)
When conducting this test, the container does not need to be equipped with its own closure device. If the test results will not be affected, the inner c
container of a composite container can be tested without an outer container. The inner container of a composite container (such as glass, ceramic or stoneware) can be exempted from the test.
6.1.17 Containers used for solids that will become liquid at temperatures that may be encountered during transportation should also have the ability to hold the liquid form of the substance.
6.1.18 Containers used for powders or granular substances should be sieve-proof or equipped with linings. 6.1.19 The inner container should be fixed and cushioned to limit its movement in the outer packaging to prevent it from breaking or leaking under normal transportation conditions. When the inner container is glass or ceramic packaging and the Class I or Class II outer packaging in 4.2 is used to contain liquids of Classes 3, 4, 8 and Item 5.1 of Class 5, and Item 6.1 of Class 6, there should be absorbent cushioning material outside the inner container. The absorbent cushioning material should not react dangerously with the dangerous goods contained in the inner container, and the leakage of the contents should not cause dangerous chemical reactions or change the protective properties of the cushioning material. 6.1.20 When using combination containers to hold dangerous goods, the closed mouth of the inner container cannot be inverted. The outer packaging should be clearly marked with a mark indicating the direction of operation.
6, 1.21 Damaged, defective, leaking or non-compliant packages of dangerous goods, or spilled or leaked dangerous goods, may be transported in salvage containers.
6.1.22 Appropriate measures should be taken to prevent damaged or leaking packages from moving excessively in the salvage container. When the salvage container contains liquid, sufficient inert absorbent material should be added to eliminate the presence of free liquid. 6.1.23 When the package is equipped with a double outer shell for water, sufficient antifreeze should be added to the water to prevent the water from freezing during transportation. 6.2 Special packaging requirements for Class 1 explosives 6.2.1 All explosive substances and articles for transport should have been classified in accordance with the procedures specified in the Model Regulations and the IMDG Code for the corresponding type of transport.
6.2.2 In addition to the general requirements of 6.1, all packagings of Class 1 explosives shall be designed and manufactured to meet the following requirements:
be able to protect the explosives so that they will not leak out or increase the risk of unintentional ignition or initiation under normal conditions of transport, including foreseeable changes in temperature, humidity and pressure; the complete packages can be safely handled under normal conditions of transport; b)
the packages can withstand any loads imposed on them by stacking during transport without increasing the hazard of the explosives c
the protective function of the packaging will not be impaired, and the packaging will not deform in a manner or degree that reduces its strength or causes instability in the stack.
Note: For air transport, if metal-lined boxes are used to pack explosive substances, the explosive substances contained in the items should not fall into the gaps between the liner and the bottom of the box or between the liner and the side wall of the box.
6.2.3 Class 1 explosives shall be packaged in accordance with the provisions of the IMDG Code for the corresponding mode of transport. 6.2.4 The packaging shall at least comply with the test requirements for Class II packaging in SN/T0370.2 and shall comply with the provisions of 5.1.4 and 6.1.17. Metal containers shall not be used for Class I packaging.
6.2.5 The closure of containers containing liquid explosives shall have a double protection device to prevent leakage. 6.2.6 The closure of metal drums shall include suitable gaskets: if the closure includes threads, the explosive material shall be prevented from entering the threads. 6.2.7 Containers containing explosive substances soluble in water shall be waterproof. Containers for transporting desensitized or desensitized substances shall be closed to prevent changes in concentration during transportation.
6.2.8 When the container includes a double layer filled with water, and the water may freeze during transportation, sufficient antifreeze should be added to the water to prevent freezing. Antifreeze agents which may cause combustion due to their inherent flammability should not be used. 6.2.9 Nails, clasps and other closures made of metal without a protective coating should not penetrate into the interior of the outer packaging unless the inner packaging is capable of preventing the explosive from coming into contact with the metal.
6.2.10 Inner packagings, fittings and cushioning materials and the explosive substances or articles should be placed in the packaging in such a way that the explosive substances or articles will not disperse in the outer packaging under normal conditions of transport. Metal parts of articles should be prevented from coming into contact with metal packagings. Articles containing explosive substances not enclosed in outer shells should be separated from each other to prevent friction and impact. Wadding, trays, partitions in inner or outer packagings, modules or receptacles may be used for this purpose.
6.2.11 The material of the packaging should be compatible with the explosive contained in the package and impermeable to the explosive to prevent interaction or leakage between the explosive and the packaging material that would make the explosive unsafe for transport or cause a change in the hazard division or compatibility group. 6.2.12 Explosive substances should be prevented from entering the recesses of seamed metal containers. 6.2.13 Plastic containers should not easily generate or accumulate enough static electricity that the discharge may cause the explosive substances or articles in the package to detonate, ignite or react.
6.2.14 Explosive substances should not be packed in inner or outer containers where the internal and external pressure differences caused by thermal effects or other effects may cause explosion or rupture of the package.

6.2.15 If loose explosive substances or explosive substances with bare shells or partially exposed articles may come into contact with the inner surface of metal containers (1A2, 1B2, 4A, 4B and metal receptacles), the metal containers should have inner linings or coatings. 6.2.16 Inner containers, accessories, cushioning materials and explosive substances should be firmly placed in the package to ensure that they will not cause dangerous movement during transportation.
6.2.17 Electric detonators shall be protected from electromagnetic radiation and stray current. Explosives equipped with ignition or initiation devices shall be effectively protected to prevent accidents under normal transport conditions.
6.2.18 For rail transport, large and solid explosive articles usually used for military purposes may be transported unpackaged if they are without initiation devices or with initiation devices containing at least two effective protective devices. When such articles are propelled or self-propelled, their initiation systems shall be protected from irritants encountered under normal transport conditions. Such unpackaged articles may be fixed to frames or packed into crates or other suitable handling and storage devices so that they will not come loose under normal transport conditions. 6.3 Special packaging requirements for organic peroxides (5.2) and self-reactive substances (4.1) 6.3.1 The packaging of organic peroxides (5.2) and self-reactive substances (4.1) shall first comply with the general requirements of 6.1. 6.3.2 For organic peroxides, all receptacles shall be "effectively closed". If the package may generate a large internal pressure due to the release of gas, it may be equipped with a vent, but the discharged gas should not cause danger, otherwise the filling degree should be limited. The structure of any venting device should prevent the liquid from leaking when the package is upright, and should prevent impurities from entering. If there is an outer container, it should be designed so that it will not interfere with the function of the venting device.
6.3.3 The container of organic peroxides with explosion hazard should also comply with other relevant requirements of the International Dangerous Goods Code for the corresponding transport mode. 6.3.4 The packaging of organic peroxides should ensure that it does not chemically react with all materials in contact with the contents and has no effect on the characteristics of the contents. When leakage occurs, the cushioning material is not easy to burn and will not cause the decomposition of the organic peroxide. 6.4 Special requirements for the packaging of dangerous goods for air transport
6.4.1 The packaging used for substances in item 4.2 (substances that are prone to spontaneous combustion) should meet the packaging requirements of Class II or above and comply with the requirements of 6.1, and metal containers shall not be used for packaging.
6.4.2 The packaging used for dangerous goods in Items 4.1 and 5.2 shall meet the requirements of Class II or above packaging and comply with the requirements of 6.1. Packaging with vents shall not be used.

1. The barrel body and barrel cover should be made of plates of appropriate model and sufficient thickness according to the capacity and purpose of the steel barrel.
For steel barrels intended to hold liquids above 40L, the barrel body seams should be welded. For steel barrels intended to hold solids or liquids below 40L, the barrel body seams can be mechanically combined or welded.
3. The flange of the barrel should be joined by mechanical methods or welded. Separate reinforcement rings may also be used.
4.Drums with a capacity of more than 60 L shall normally have at least two expansion hoops or at least two separate hoops. If separate hoops are used, they shall be fixed to the drum and shall not move. Hoops shall not be loose. The diameter of the openings in the drum or lid of non-removable (1A1) drums for filling, emptying and ventilation shall not exceed 7 cm. Drums with larger openings shall be considered removable (1A2) drums. Closures on the openings of the drum body and lid shall be designed and installed so that they are always tight and leakproof under normal conditions of transport. The flanges of the closures shall be properly joined by cutting or welding. Unless the closures themselves are leakproof, gaskets or other seals shall be used. Closures on removable-head drums shall be designed and installed so that they are always tight and the drum is always leakproof under normal conditions of transport. All removable lids shall use gaskets or other seals. 7. If the materials used for the barrel, lid, closures and connectors are incompatible with the substances being transported, appropriate internal protective coatings or treatments should be applied. These coatings or treatments should always maintain their protective properties under normal conditions of transport. The barrel and lid should be made of aluminum with a purity of at least 9%, or an aluminum-based alloy. The appropriate type and sufficient thickness of material should be used according to the capacity and purpose of the aluminum barrel.
2. All seams should be welded. If there are seams on the flange, additional reinforcement rings should be added.
3. The barrel of aluminum barrels with a capacity greater than 60L should usually be equipped with at least two expansion roll hoops or two split roll hoops. If split roll hoops are installed, they should be installed firmly and should not move. Roll hoops should not be spot welded. 4. The diameter of the openings on the barrel or lid of non-removable head (1B1) aluminum barrels for filling, emptying and ventilation should not exceed 7cm. Aluminum barrels with larger openings will be regarded as removable head (1B2) aluminum barrels. The design and installation of the closures of the barrel and the lid should be such that they are always tight and leak-proof under normal transport conditions. The flanges of the closures should be properly welded to make the seams leak-proof. Unless the closure itself is leak-proof, a gasket or other seal should be used. 5. The closures of aluminum drums with movable lids should be designed and installed so that they are always tight and leak-proof under normal transport conditions. All movable lids should use gaskets or other seals.
