The International Maritime Organization (IMO) is the United Nations’ specialized agency responsible for the safety, security, and environmental performance of international shipping. Established in 1948 (as IMCO) and headquartered in London, it develops and maintains the global regulatory framework for maritime transport through conventions, codes, and guidelines adopted by its member states. Key instruments include SOLAS (safety), MARPOL (pollution prevention), and the STCW Convention (seafarer training).
For the chemical industry, the IMO sets the rules that govern the seaborne transport of hazardous substances and bulk chemicals. The IMDG Code regulates classification, packaging, labeling, and stowage of dangerous goods in packaged form; the IBC Code covers the construction and equipment of ships carrying dangerous chemicals in bulk; and the IGC Code addresses liquefied gas carriers. MARPOL Annex II governs noxious liquid substances and cargo handling to prevent pollution. The organization also sets fuel sulfur limits and greenhouse gas reduction measures that affect chemical and petrochemical shipping operations worldwide. Together, these standards provide the global baseline for safe, secure, and environmentally responsible maritime transport of chemicals.
