What is the UN number and packing class for methyl methacrylate by sea?

Resolution of UN number and packing grade for methyl methacrylate shipping

methyl methacrylate (MMA) is an important chemical raw material, which is widely used in plastics, coatings and resin manufacturing. Due to its flammability and toxicity, international regulations for the transport of dangerous goods by sea must be strictly observed. This article will analyze in detail the UN number and packaging grade required for methyl methacrylate shipping to help relevant practitioners understand the transportation requirements.

1. UNs for methyl methacrylate

In the international transport of dangerous goods, each substance has a unique UN number. The UN number of methyl methacrylate is UN 4284. This number is unified worldwide and is used to identify the type and nature of dangerous goods to ensure safety and standardization during transportation. The existence of a UN number allows transport, customs and security agencies in different countries to quickly identify the danger of goods and take appropriate security measures.

2. methyl methacrylate hazard classification

Methyl methacrylate belongs to the category of flammable liquids and is classified as 3 dangerous goods. According to the rules of the International Maritime Organization (IMO) on the transport of dangerous goods, its risk is mainly reflected in the flammability and toxicity to human body. Therefore, the packaging and storage of MMA in maritime transport must meet strict standards for the transport of dangerous goods.

3. methyl methacrylate packaging grade

According to the regulations on the transport of dangerous goods, the packaging grade of methyl methacrylate is divided into three categories: Class I, Class II and Class III packaging. Choosing the appropriate packaging grade depends on the specific hazards of the goods, the amount of transportation and the safety of the packaging materials.

1. Type I packing: suitable for high-risk goods, requiring the highest level of protection measures. MMA packaging must use high-strength, corrosion-resistant materials, such as steel or special plastic containers, and require additional shock and leak-proof measures.

2. Class II packaging: suitable for moderately dangerous goods, the requirements for packaging materials are slightly lower than Class I, but still need to have good sealing and impact resistance. Usually high-quality plastic or metal containers are used.

3. Class III packaging: suitable for low-risk goods, the requirements for packaging are relatively low, but it is still necessary to ensure tightness and basic impact resistance. Suitable for small batch transportation.

4. maritime transport specific requirements

1. Document preparation: In maritime transport, the carrier must prepare a complete declaration of dangerous goods, including the UN number, hazard classification, packaging grade and other information of the goods. These documents will be submitted to the port management and relevant security agencies to ensure the legality of the transport process.

2. Marking and Labeling: All packaging must be clearly marked with UN number, danger mark and transportation notice. For example, the marking of flammable liquids must be clearly visible so that transport and handling personnel can quickly identify the nature of the cargo.

3. LOADING AND STORAGE: On board, MMA must be stored in the designated dangerous goods area, away from fire and high temperature areas. The packaging must be stable to avoid leakage or breakage due to ship shaking.

5. the importance of safe transportation

The danger of methyl methacrylate requires that its shipping must strictly follow international standards. Any operation in violation of transportation regulations may lead to serious consequences, including loss of goods, environmental pollution and casualties. Therefore, enterprises must strengthen staff training, ensure that all operations comply with relevant laws and regulations, and cooperate with professional logistics companies to ensure the safety of the transportation process.

6. summary

The UN number of methyl methacrylate is UN 4284, and its packaging grade is divided into categories I, II and III according to danger. In maritime transport, packaging, marking and storage must be carried out in strict accordance with the international rules for the transport of dangerous goods. Ensuring the safe transportation of goods is not only a legal requirement, but also an important manifestation of corporate social responsibility. Only through standardized operation and strict management can we effectively reduce transportation risks and ensure the safety of personnel and the environment.
