Dangerous goods consignment is the first step in the ocean export of dangerous goods, involving multiple stages such as carrier qualifications, document completion, packaging acceptance, and declaration of product names. An error in any stage may affect acceptance for carriage or create transport risks. This article clearly explains the points to note in dangerous goods consignment, the required documents, and the complete process. For the corresponding classification system of dangerous goods, see Classification of Dangerous Goods: Criteria for Dividing the Nine Major Categories of Dangerous Goods; for an overview of the IMDG Code, see Dangerous Goods Container Transport: IMDG Code, Marks, Signs, and Declaration Requirements; for the customs declaration stage of dangerous goods, see What to Note in Customs Declaration for Dangerous Goods.
I. Verify the carrier’s qualifications and acceptance scope before consignment
Consignment should be arranged with a carrier that holds the operating qualification for the transport of dangerous goods. For ocean export, confirm whether the shipping company carries the corresponding dangerous goods class, and whether the port container stuffing and port area have operations and storage support for the corresponding class. Different shipping companies have different acceptance policies for dangerous goods, space availability, and destination port restrictions; these should be confirmed before booking to avoid cancellation or booking amendments after booking.
II. Fill Out the Consignment Note and Specify the Product Name and Documents
On the consignment note, clearly enter the name, specifications, weight per package, number of packages, packing method, date of dispatch of the dangerous goods, detailed addresses of the consignor and consignee, and precautions during transport. For dangerous goods with special requirements or requiring certificates for transport, the relevant documents must be attached and noted in the remarks column of the consignment note. The declared product name shall use the correct UN number and proper shipping name, and colloquial or trade names shall be avoided.
For dangerous goods requiring certificates for transport, the corresponding certificates shall be held. For example, explosives and dangerous chemical goods requiring certificates for transport usually require a transport permit issued by the public security department; radioactive goods require a certificate of inspection of package surface contamination and radiation levels issued by the designated health and epidemic prevention (or competent) department. The specific certificates shall be subject to the cargo category and port requirements.
III. Standardized Packaging and Marking Labels
The packaging of dangerous goods shall comply with UN certification standards. Appropriate dangerous goods packaging containers shall be selected according to the packing group, and correct dangerous goods markings and labels shall be affixed to packages and transport containers. Dangerous goods whose properties or fire-extinguishing methods conflict with each other must have separate consignment notes filled out and be handled separately to prevent accidents caused by mixed loading. When consigning new varieties not listed in the corresponding List of Dangerous Goods Names, it is usually necessary to submit a Dangerous Goods Identification Form reviewed by the competent department and, after approval, arrange transport.
IV. Complete Process for Consigning Dangerous Goods
Consigning dangerous goods involves multiple steps, and the cargo owner may proceed as follows:
- Determine the dangerous goods category—Determine the UN number, dangerous goods class, and packing group based on the cargo properties.
- Prepare safety documentation—Prepare the MSDS (Safety Data Sheet) and dangerous goods declaration.
- Select compliant packaging—Use UN-certified dangerous goods packaging containers and ensure the packing group meets requirements.
- Affix transport labels—Affix the correct dangerous goods hazard labels to packages and transport containers.
- Declare to the shipping company—Submit the dangerous goods declaration and MSDS when booking; shipment may proceed only after confirmation.
- Customs declaration—Declare the dangerous goods export to customs and provide complete dangerous goods information and documents.
Dangerous goods consignment must strictly comply with the International Maritime Dangerous Goods Code (IMDG Code) and relevant domestic regulations. Non-compliant consignment will face fines, return of shipment, or even legal liability.
Data note: The above are general operational requirements for dangerous goods consignment. Specific documents, packaging, and declaration requirements shall be subject to the current IMDG Code, the destination country, and the shipping company’s confirmation for that shipment.
Frequently Asked Questions (FAQ) About Dangerous Goods Consignment
Q: How far in advance should ocean freight booking for dangerous goods be made?
A: It is recommended to book as early as possible, leaving sufficient time for carrier review and space confirmation. For dangerous goods bookings, documents such as the Dangerous Goods Packaging Certificate and MSDS must first be submitted to the shipping line for review. Review and booking confirmation usually take anywhere from several days to a week; during peak season, book even earlier to allow sufficient time for both the shipper and the freight forwarder. The specific time limit is subject to the carrier’s booking for that particular shipment.
Q: How should the commodity name for dangerous goods be filled in to be compliant?
A: The correct UN number and proper shipping name should be used, and colloquial or commercial aliases should be avoided. The commodity name, UN number, class, and packing group should correspond to one another. Note special requirements and certificates in the remarks of the shipping instruction to ensure document consistency and traceable declaration.
