五. Container password and identification

Container , usually we also call it "container", refers to a large loading container with a certain strength, rigidity and specifications for turnover. There are many classifications of containers and their uses are also very different. Today let’s talk about small details that everyone may not know well. —Container number (container number for export goods) The standard container number consists of 11-digit codes, including three parts: the first part consists of 4 English letters. The first three codes mainly indicate the container owner and operator, and the fourth code indicates the type of container. The second part consists of 6 digits. It is the container registration code, which is used for the unique identification held by a container body. The third part is the check code, which is obtained from the first 4 letters and 6 numbers through the calculation of the check rule, and is used to identify whether an error occurs during the check. That is the 11th digit.

六.conatiner type

What are the commonly used sizes and types of containers? 20GP, 40GP and 40HQ are the three most commonly used containers. They look like this: 1) The size of 20GP is: length 20 feet X width 8 feet X height 8.5 feet, referred to as 20 feet general container 2) The size of 20GP is: length 20 feet X width 8 feet X height 8.5 feet, referred to as 20 feet general cabinet

container identification

(1) Size and box type code.

A total of 4 digits, the first digit indicates the length of the box, the second digit indicates the height of the box, and the last two digits indicate the box type.

(2) Weight and volume markings.

From top to bottom are gross weight, tare weight, net weight, and volume. Weight is expressed in kilograms (KG) and pounds (LB) at the same time, and volume is expressed in cubic meters (CU.M.) and cubic feet (CU.FT.) at the same time marked.

MAXIMUM GROSS WEIGHT (gross weight): It is the sum of tare weight + net weight, see this number for bridge crane load and road weight limit. TARE WEIGHT (tare weight): the weight of the empty box. PAYLOAD or NET WEIGHT (net weight): the maximum weight that the container can carry. CUBIC CAPACITY (cubic volume): the maximum loading volume of the container.

(3) Overweight mark.

For overweight containers (total weight over 30.48 tons), you can see the triangle overweight mark of "SUPERHEAVY" as follows.

(4) SUPERHIGH MARKING.

All containers over 2.6 meters (8'6") high must post the following two types of marks: a. Height marks should be posted on both sides of the container, placed at a position 0.6M to the right of 1.2M from the top, with black characters on a yellow background. The mark is divided into two parts, the value of the upper part is in meters, and the value of the lower part is the value converted into imperial units. The icon mark indicates that the height of the cabinet is 2.9M (9 feet 6 inches). b. Both sides of each corner piece of the top beam Paste a yellow and black zebra mark not shorter than 300mm.

The IC mark on the box indicates which country the box has applied for UIC certification. Since the container is universal, as long as it applies for the certification of any member country of the International Union of Railways, it can be approved for global railway transportation.

(6) CSC safety qualification license.

CSC is the abbreviation of "International Convention for Safe Container". In accordance with the provisions of the appendix to this appendix, the safety clearance plate shall be permanently mounted on each approved container in a conspicuous and indestructible place adjacent to other approval plates issued for official use.

Some countries and regions are particularly sensitive to certain types of quarantine objects, especially in countries such as Australia and New Zealand in Oceania, which must have a license plate with wood quarantine treatment before entering the country. The principle of TCT stipulates that every container approved by TCT should be permanently equipped with a quarantine license, which should be installed in an obvious and not easy to be damaged position near the license issued by other authorities. The formula for the anti-epidemic treatment of the wooden floor on each container body should be listed in the "Container Quarantine Inspection Procedures" issued by the Australian Ministry of Basic Industry and Energy, and it is completely consistent with the content shown on the quarantine license . This approval shall be void if the exposed timber of the container is replaced during repairs and refurbishments.

(9) Classification Society Certification License This certification indicates that the container complies with the classification society's container inspection regulations and related requirements.
