2023-11-21

Case 1: 

On December 1, 2019, law enforcement officers from the Jieyang Maritime Safety Bureau discovered "Fish Meal" inside a container during on-site inspection at a dock in Jiedong.

After further investigation, it was found that the goods were UN2166, IMO Class 9 maritime dangerous goods. Rongcheng Company, through a freight forwarding company's booking plan, transported the above-mentioned goods to the jurisdiction of Jieyang Jiedong. However, the shipper mistakenly identified "fish meal" as ordinary goods for transportation when handling the shipping procedures, and did not inform the carrier of the official and proper shipping name, dangerous nature, and protective measures that should be taken of the dangerous goods that being shipped. In violation of Article 63 (1) of the Maritime Traffic Safety Law of the People's Republic of China, the maritime department has imposed administrative penalties on the shipper in accordance with the law.

 

Case 2

On April 29, 2022, law enforcement officers from the Guangzhou Maritime Safety Bureau conducted an on board container inspection on a vessel at a port in Guangzhou. They found that the cargo "dry feed" contained in a container carried by the ship on that voyage was suspected to be dangerous goods. At the time of booking, the cargo was named "dry feed" and the booking procedures were handled as ordinary goods.

 

After sampling and inspection, the "Hazardous Characteristics Classification and Identification Report" issued by the Guangzhou Customs Technical Center indicates that the goods are UN2166, Class 9 maritime dangerous goods; The official shipping name of the goods is: Fish Meal; The company in Wenzhou is the shipper of the goods. The company falsely reported dangerous goods as ordinary goods, violating the provisions of Article 63 (2) of the Maritime Traffic Safety Law of the People's Republic of China. The maritime department has imposed administrative penalties on the shipper in accordance with the law.

 

 

Analysis of Fish Meal:

Fish meal "is classified as Class 4.2 dangerous goods in the international hazardous regulations (without antioxidant treatment, with a mass moisture content greater than 5% and less than 12%, and a mass fat content not exceeding 12%) and Class 9 (with antioxidant treatment, with a mass moisture content greater than 5% and less than 12%, and a mass fat content not exceeding 15%).

Fish meal is prone to spontaneous combustion, mainly due to:

1. Fish meal contains high levels of fat, which is prone to oxidation and heating up, which is one of the reasons for the spontaneous combustion of fish meal.

2. High calcium and phosphorus content: Fish meal contains 3.8% -7% calcium and 2.76% -3.5% phosphorus, with a calcium phosphorus ratio of 1.4-2:1. During storage, phosphorus is released due to chemical decomposition and becomes elemental phosphorus. Simple phosphorus has a low ignition point and can ignite spontaneously without the need for an open flame.

3. Due to the high salt content of fish meal, it is easy to absorb moisture, which is conducive to the reproduction of bacteria, mold, and yeast, causing temperature rise, often clumping, moldy, and even spontaneous combustion.


The conclusion of above two cases.

(1) Case 1: The shipper lacks strong safety awareness and professional level, mistakenly identifies the nature of the goods, and delivers and transports dangerous goods "fish meal" as ordinary goods; In this case, the shipper did not grasp the hazardous characteristics of fish meal, resulting in the illegal fact of not shipping according to regulations, which is applicable to Article 63 (1) of the Maritime Safety Law.
