UN Number and Packing Grade Specification for MIBK Shipping?

Specification for UN Numbers and Packing Grades for MIBK Shipping

maritime transport of hazardous chemicals is a highly regulated operation in the global chemical industry, especially when it comes to flammable liquids such as methyl isobutyl ketone (MIBK). As a chemical industry practitioner, understanding MIBK Marine's UN numbering and packing grade specifications is key to ensuring transportation safety, compliance and reducing potential risks. This article will analyze in detail the importance of UN number in MIBK shipping, the specification requirements of packaging grade, and how to ensure safety during transportation.

1. The basic nature of MIBK and the need for maritime transport

methyl isobutyl ketone (MIBK) is a colorless and flammable organic compound, which is widely used in solvents, paint thinners, organic synthesis and other fields. Due to its flammability, MIBK is classified as a hazardous chemical, and according to the United Nations standards for the transport of dangerous goods, MIBK belongs to Class 3 flammable liquids. This means that MIBK must be packed and transported in accordance with strict regulations for the transport of dangerous goods during sea transport.

2. The role and significance of UN number

in the transport of hazardous chemicals, the UN number is an internationally accepted marking system used to clarify the hazardous nature of the goods and the transport requirements. The UN Number is a unique identifier based on the United Nations Recommendations on the Transport of Dangerous Goods (TDG) or the International Maritime Dangerous Goods Code (IMDG). The UN number of MIBK is UN 1223, which indicates that MIBK belongs to the category of flammable liquids and needs to be handled according to the corresponding dangerous goods transportation requirements.

The purpose of UN numbering is to ensure that transport operators worldwide can quickly identify the hazardous nature of the cargo and take appropriate protective measures. For maritime transport, the UN number is not only used for the labeling of goods, but also for determining the specific requirements of transport packaging, marking and documentation.

3. Specification for packing grades of MIBK

according to the IMDG rules, the packaging grade of hazardous chemicals is classified according to their hazard, which is usually divided into different categories. As a flammable liquid, MIBK's packaging level mainly depends on its physical properties such as flash point and initial boiling point. Specifically, MIBK's packaging grade needs to meet the following requirements:

• packaging category: MIBK belongs to the category of flammable liquids and is usually classified as Class 3 flammable liquids, so its packaging must meet the transportation standards for flammable liquids.
• Packaging Materials: Because MIBK is flammable and volatile, the transport packaging should be made of materials that meet the requirements for the transport of dangerous goods, such as steel drums, aluminum drums or plastic containers that meet the standards. The packaging must have sufficient leak resistance to prevent leakage of the goods.
• Test Standard packaging containers need to pass a series of tests, including stacking tests, drop tests and tightness tests, to ensure that they can withstand extreme conditions such as vibration, pressure and temperature changes during shipping.

4. Specification for Labeling and Marking in MIBK Shipping

in addition to the packaging level, MIBK's shipping labels and markings are also an important part of ensuring transportation safety. According to the rules for the transport of dangerous goods, the following information must be clearly marked on each packaging container:

• UN Number: UN 1223.
• Category of dangerous goods flammable liquids, Class 3.
• FIRE PROTECTION IDENTIFICATION: Identification symbol for flammable liquids.
• Precautions: such as "away from fire", "good ventilation" and other warning words.
• Name of Goods: MIBK or its chemical name.

These labels and markings must comply with international standards to ensure that port staff, crews and container operators can quickly identify the hazardous nature of the cargo and take appropriate protective measures.

5. Summary and Compliance Recommendations

MIBK's maritime transport involves complex regulations for the transport of dangerous goods, including the determination of UN numbers, classification of packaging classes, and labeling and marking requirements. As a practitioner in the chemical industry, understanding and complying with these regulations is fundamental to ensuring transportation safety and compliance.

In practice, it is recommended to cooperate with professional dangerous goods transportation companies to ensure that all packaging and labeling meet international standards. The understanding of the rules for the transport of dangerous goods is regularly updated in response to possible regulatory changes and technological advances.

MIBK's shipping needs to strictly follow the UN number and packaging grade specifications, only in this way can ensure the safe transportation of goods, reduce potential environmental and personal risks, and avoid economic losses caused by illegal operations.
