Surcharge Tariffs, Dangerous Cargo Rules and Container Specifications
The rate announcement feed is a dataset in its own right. Each notice carries a surcharge code, a scope, a direction and an effective date, and the amounts are broken out by equipment. A bunker notice, for example, quotes 20DRY, 40DRY, 40HDRY and 45HDRY separately from 20REEF and 40REEF, and splits All Long Hauls headhaul from backhaul and from intra trades. The recurring codes are worth learning: PSS for peak season, EBS for emergency bunker, ECS for emergency contingency, LSS for low sulphur, EMS and ESS for emissions, HWS for heavy load, LWC for low water, DPS and DPI for dry port, IPE and IPI for inland peak, PAE and PAI for port additionals, ODC and DDC for dangerous cargo handling, plus terminal handling and the demurrage and detention revisions published country by country.
Dangerous cargo runs on the IMDG Code and the published restrictions are explicit rather than generic. Classes 1.5, 1.6 and 6.2 are not accepted; nor is tantalum or tantalite outside IMDG class 7, nor thiourea dioxide from China. A short list of class 5.1 chlorinated isocyanurates is accepted on deck only. Dangerous goods in flexitanks are refused outright, and misdeclaration carries a stated administrative fee per bill of lading, higher per container for China.
Alongside that sit the equipment tables, where every container type publishes maximum payload, tare weight and maximum gross weight in kilograms, and the per country pages that list depots with their gate hours and cut off times.
