There’s always doubt when it comes to handling DG / Hazardous material for transportation by sea. Following a good source i found on the net (source: Fourstarcargoinc) serving as a guide. Find this rather useful.

According to the U. S. Department of Transportation (DOT), a hazardous material is “A substance or material, including a hazardous substance, which has been determined by the Secretary of Transportation to be capable of posing an unreasonable risk to health, safety and property when transported in commerce, and which has been so designated.” In layman’s terms, this means any material that, because of its chemical properties, may cause injury, loss of life, damage to property or the environment if involved in an accident during transportation. A minor transportation accident can quickly escalate into a major catastrophe when hazardous materials are involved. There are currently two sets of regulations covering the shipping of hazardous materials. International Maritime Dangerous Goods Code regulations
Code of Federal Regulations (CFR-49)
The two sets of regulations are very similar in documentation, labeling, marking, and placarding requirements. However, some differences do exist. Whenever these regulations conflict, the more stringent of the two must be adhered to. The shipper or their agent is responsible for having their Hazardous Material cargo in compliance with all the regulations at the time the cargo is offered for transportation (at the time of pick up from the shipper’s facilities, or at the time of delivery to the carrier’s terminal). The carrier’s (highway, ocean, rail, air) responsibility is to determine that the shipper has, in fact, complied to the regulations before the carrier transports the cargo. A signed “shipper’s certification” statement is required. There are several types (classes) of Hazardous Materials. Most classes of Hazardous Materials are accepted for transport by Four Star Cargo, but there are a few classes that, because of their extreme danger, Four Star does not handle. The following are lists of Hazardous Materials that are and are not accepted/transported by Four Star:
Hazardous Material accepted by Four Star Cargo Hazardous Material NOT ACCEPTED by Four Star Cargo Class 1.3, compatibility groups: *Not all shipments can be shipped to all ports. Contact your Customer Service Representative for specific restrictions. The person offering the Hazardous Material for transportation (usually the shipper) must provide a shipping paper to the carrier. This document must contain the following information ( taken from the CFR-49 and IMDG Code):
“I hereby declare that the contents of this consignment are fully and accurately described above by the correct technical name(s) (Proper Shipping Name [s]), and are classified, packaged, marked and labeled/placarded, and are in all respects in proper condition for transport according to the applicable international and national government regulations.” Signature on behalf of Shipper Note: Empty tanks/cylinders that last contained a Hazardous Material must still be classified as a Hazardous Material because of the residue. The description would begin with “Residue, Last Contained”, followed by the proper shipping name. Note: There may be exceptions to the packaging/labeling/marking/placarding requirements when certain classes of Hazardous Materials are shipped in limited quantities. This exception is dependent on the Hazard Class, packaging group, physical state of the substance, and maximum quantity allowed for each inner package. Hazardous Materials shipped in this manner must be described as “Limited Quantities” by the shipper. Any quantity of Hazardous Material must be placarded for ocean transport. Note: Placarding exception exists for limited quantity shipments and for shipments where individual packages require no labels. HAZARDOUS MATERIALS COMPATIBILITY CHART Do not load any type of cargo with foodstuffs that has a strong odor/smell. (Example: mothballs, pine oils, paints, gas cylinders, etc. The odors may cause contamination to the foodstuff or packaging.)
