According to the observation report of Huacheng import and export data, in recent years, with the increase of China's import and export freight market exchanges, there has also been a major breakthrough in the export of dangerous chemicals. If there are problems in packaging, the loss will be incalculable. In order to strengthen the inspection, supervision and management of the marine cargo packaging of dangerous chemicals, ensure the safety of production, personal and transportation, and expand exports, the inspection system is implemented for the packaging of marine export dangerous goods within the scope of the International Maritime Dangerous Goods Transport Code. The following Juhai Supply Chain Editor will take you to see what China's regulations and standards are in the marine cargo of dangerous chemicals.

1. Competent Authority

Local commodity inspection bureaus are responsible for supervising and managing the inspection of the packaging of dangerous goods for export by sea in their respective regions, and handling the performance appraisal and use appraisal of the packaging of dangerous goods for export.

2. Production inspection of packaging containers

Factories that produce packaging containers for dangerous goods exported by sea shall register with the commodity inspection authorities. The manufacturer must organize the production of dangerous goods packaging according to the requirements of the International Dangerous Goods Regulations, establish an inspection system, equip inspection personnel and equipment, strengthen quality management and product inspection, and observe and report the import and export data of Huacheng.

The manufacturer shall apply to the commodity inspection authority for performance appraisal on the basis that the production inspection of packaging containers is qualified. During the application, the product standards, process procedures and factory inspection results of the packaging containers shall be provided. During the period of regular identification by the commodity inspection authority, if the manufacturer needs to change the product standards and processing technology, it shall timely reapply to the commodity inspection authority for identification. Packaging containers produced by the manufacturer must be cast or marked with the manufacturer code and batch number approved by the commodity inspection authority. For packaging containers that have stable performance and can fully meet the requirements of the International Dangerous Goods Regulations, the manufacturer can apply to the commodity inspection authority for commodity inspection marks, and Huacheng's import and export data observation report.

3. Use inspection of packaging containers

When using packaging containers, manufacturers of dangerous goods shall apply to the commodity inspection authorities for use identification batch by batch. The name, nature, category, etc. of the dangerous goods to be exported shall be indicated in the application. The manufacturer of dangerous goods shall use the packaging containers according to the requirements of the International Dangerous Goods Regulations by virtue of the performance appraisal certificate of the packaging containers issued by the commodity inspection authority. Packaging containers provided by foreign businessmen can be used if they are attached with performance appraisal certificates to prove that they meet the requirements of the International Dangerous Goods Regulations. When plastic containers or inner paint containers are used to contain liquid dangerous goods, the manufacturer of dangerous goods must obtain the chemical property compatibility test results. Only those meeting the requirements can be used.

4. Package identification of dangerous goods

The commodity inspection authorities shall, on the strength of their applications, handle the inspection of the packages of dangerous goods exported by sea and issue the inspection certificates. The appraisal items are: performance appraisal and use appraisal. The commodity inspection authorities shall, according to different conditions and needs, carry out packaging identification by means of batch inspection, regular inspection and irregular sampling inspection. The commodity inspection agency handled the identification of the packaging of dangerous goods exported by sea and charged a reasonable identification fee. Huacheng Import and Export Data Observation Report.

1、 Classification of transport packages for dangerous goods

The packaging of hazardous chemicals (except Class 1: explosives, Class 2: compressed gases and liquefied gases, Class 6.2: spontaneously combustible materials, and Class 7: oxidants and organic peroxides) is divided into three categories according to the degree of risk.

Class I packaging: the goods are of great danger, and the requirements for packaging strength are high;

Class II packaging: the goods are moderately dangerous, and the requirements for packaging strength are high;

Class III packaging: the goods are of small danger, and the requirements for packaging strength are generally low;

2、 Rules for packaging requirements for transport of dangerous goods

1. When filling liquid dangerous goods, the container shall have enough expansion margin for high temperature during normal transportation. Flammable liquid containers shall have at least 5% clearance.

2. The packing liner shall not react with the intended contents to reduce the safety, and shall be able to prevent the movement of the contents and play the role of shock absorption and absorption.

3. The packaging surface shall be clean and shall not adhere to the contents and other harmful substances.

4. The material, specification and packaging structure of the packaging materials shall be consistent with the nature and weight of the dangerous goods. The packaging container and the proposed contents shall not react dangerously or weaken the packaging strength.

5. The liquid dangerous goods shall be liquid sealed; Gas tight sealing shall be provided for those that may produce harmful vapor and are prone to deliquescence or may react dangerously when encountering acid mist. Containers that must be equipped with air vents shall be designed and installed to prevent goods from flowing out or entering impurities and moisture, and the discharged gas will not cause danger or pollution. The packaging of other dangerous goods shall be sealed without leakage.

Now let's take a look at the packaging requirements for dangerous chemicals?

1、 Packaging requirements for explosive and flammable materials

1. Packed in plastic drums and put into iron or wooden boxes

2. The weight of explosives in each barrel shall not exceed 50kg.

3. The explosion-proof barrel is equipped with a safety valve, and the pressure in the barrel can be automatically deflated and adjusted when it rises

2、 Packaging requirements for toxic substances

The main requirements are not breathable and tightly packed.

1. There must be obvious signs of toxic substances.

2. Toxic crystals, such as potassium dichromate and sodium dichromate, shall be packed in solid attached barrels, with tight opening and no leakage, and the barrel wall shall not be less than 1.2 mm.

3. For organic pesticides, use asphalt sacks with tight seams. If plastic bags or asphalt paper bags are used for packaging, gunny bags or cloth bags shall be used for packaging.

3、 Packaging requirements for corrosive articles

The key to packaging corrosive articles is to pay attention to the changes between articles and containers.

1. Metal containers need to be coated with anti-corrosion paint to prevent corrosion of metal containers caused by corrosive articles. as

2. Hydrofluoric acid cannot be used in glass containers, which will be corroded. Plastic or metal drums shall be used.

3. For volatile corrosives such as formic acid, acid resistant containers shall be used, sealed and stored in wooden cases.

The packaging of dangerous goods is very important to the safety of loading, unloading and transportation of dangerous goods, and must be operated according to the packaging requirements of dangerous goods.
