CHICAGO - As of Jan. 1, 2010, the International Maritime Dangerous Goods Code (IMDG) requirements for marine pollutant markings will be mandatory for all applicable shipments. The DOT requirements for the use of the new marking were in effect as of Jan. 14, 2010. Labelmaster, Chicago, IL, currently carries the revised marine pollutant marking and has on-staff experts for any questions regarding the new classification regulations.
 
The required marking, also known as the environmentally hazardous substance marking, was designed to help shippers and transporters easily identify any liquid or solid materials, including its mixtures and solutions, that are classified as marine pollutants.
