What is the UN number and packing grade for shipping acetic acid?

In the chemical industry, the transport of dangerous goods is an extremely important and complex task, especially in the maritime sector. As one of the common hazardous chemicals, acetic acid needs to follow strict regulations in international shipping, including the determination of UN number and packaging grade. This article will give you a detailed analysis of the UN number and packaging grade of acetic acid shipping to help you better understand and comply with relevant regulations.

1. UN Number Importance

The UN number is a unique identification code assigned to each hazardous chemical in the United Nations system for the transport of dangerous goods and is used worldwide for transport management and risk assessment. As a flammable liquid, acetic acid has a certain degree of danger, so it has been given a specific UN number.

According to the United Nations Recommendations on the Transport of Dangerous Goods (TDG), the UN number for acetic acid is UN 1746. This number is widely accepted worldwide and is used to identify the hazardous properties of acetic acid, packaging requirements and shipping conditions. Whether transported by sea, air or land, UN numbers are an integral part of international trade and logistics.

2. acetic acid packaging classification

In the transport of dangerous goods, the packaging level is divided according to the dangerous degree of the goods and the packaging requirements. As a flammable liquid, the packaging grade of acetic acid is mainly determined by its physical and chemical characteristics. The following are common packaging grades and their scope of application in acetic acid shipping:

1. Packing Class I Suitable for high-risk liquid cargo. Although acetic acid is flammable, due to its low flash point (about 41°C), it is usually not necessary to use Class I packaging in marine transportation. Class I packaging is mainly used for liquids that are extremely flammable and highly hazardous, such as hydroperoxides.

2. Packaging Class II Suitable for medium dangerous liquid cargo. Acetic acid is a relatively low hazard, so it is common to use Group II packaging in ocean shipping. Class II packaging requires the use of standard medium-strength packaging materials, such as steel drums, aluminum drums or plastic drums, to ensure that leakage and combustion can be effectively prevented during transportation.

3. Packaging Class III Suitable for low-risk liquid cargo. Due to the low risk of acetic acid, Group III packaging may also be selected in some cases. The requirements for Class III packaging are relatively relaxed and are applicable to non-hazardous liquids or liquids with very low risk.

3. why packaging classification is so important?

The classification of packaging grades is directly related to transportation safety and regulatory compliance. The following is the importance of packaging classification:

1. Ensure transport safety Different packaging grades are suitable for goods with different degrees of danger. Scientific classification of packaging grades can effectively reduce the risk during transportation. For example, the packaging of flammable liquids must be able to withstand certain pressure and temperature changes to avoid accidents due to leakage or rupture.

2. Compliance with international regulations Worldwide, the transport of dangerous goods must comply with regulations such as the International Maritime Dangerous Goods Code (IMDG Code). These regulations have clear regulations on packaging levels to ensure that transportation standards are consistent between countries and to avoid safety hazards caused by inconsistent regulations.

3. Reducing environmental risks As a flammable liquid, acetic acid may pollute the marine environment if it leaks during transportation. Through reasonable packaging classification and packaging material selection, the risk of leakage can be effectively reduced and the environment can be protected.

4. how to choose the right packaging grade?

When choosing the packaging grade of acetic acid, the following factors need to be considered:

1. Hazardous characteristics of the goods The flash point and flammability of acetic acid are the key factors in determining the packaging grade. Depending on its hazardous characteristics, Group II or Group III packaging can be selected.

2. Mode of transport The special environmental conditions of shipping (such as humidity, temperature, salt spray, etc.) require packaging materials to have higher durability. Therefore, when choosing a packaging grade, it is necessary to consider the particularity of the marine environment.

3. Regulatory requirements Regulations in different countries and regions may vary, so when selecting a packaging grade, you must be familiar with the relevant regulatory requirements to ensure compliance with the transportation process.

5. summary

As an important chemical product, acetic acid must follow strict regulations for the transport of dangerous goods by sea. Its UN number is UN 1746, and the packaging grade is usually selected for Class II or Class III packaging. Through the scientific classification of packaging and the selection of packaging materials, the transportation risk can be effectively reduced and the safe arrival of the goods can be ensured.

For enterprises engaged in acetic acid shipping, it is essential to understand and comply with relevant laws and regulations. Only under the premise of ensuring safety and compliance can the transportation of dangerous goods be successfully completed. If you still have questions about the UN number or packaging grade of acetic acid, it is recommended to consult a professional dangerous goods transportation consultant or consult the relevant regulatory documents to ensure that the transportation process is foolproof.
