    • The estimated date and time of the vessel’s arrival in the case of DG for discharging or in transit must be stated.

  • Ammonium Nitrate
    • Certificate of Analysis (COA) issued by a body deemed competent by the Authority. The percentage of total combustible matter (including organic matter calculated as carbon) must be clearly stated in the certificate.

  • Nuclear Material
    • From 22 October 2014, all transit of nuclear material through Singapore will require a licence from the National Environment Agency (NEA) Radiation Protection and Nuclear Science Department (RPNSD). The nuclear material is as defined under Radiation Protection Act (RPA) and extracted below:
    • “Nuclear Material” means:
      • Plutonium except for plutonium with an isotopic concentration of plutonium-238 exceeding 80%;
      • Uranium-233;
      • Uranium containing uranium-233 or uranium-235 or both in such an amount that the abundance ratio of the sum of those isotopes to uranium-238 is greater than the ratio of uranium-235 to uranium-238 occurring in nature;
      • Uranium with an isotopic concentration equal to that occurring in nature; or
      • Any material containing one or more of the foregoing, that is used for peaceful purposes but does not include uranium in the form of ore or ore residue.
    • The license fee is $40 per consignment, similar to the current license fee for import and export of radioactive material.
    • In addition to NEA’s license, approval from Maritime and Port Authority of Singapore (MPA) is also required for shipment of nuclear material transiting through Singapore.
  1. For submission storage of Dangerous Goods (DG) at the terminals, port users should inquire with the relevant terminal operators and obtain their approval where necessary.


  1. Please note that some Dangerous Goods (DG) are also strategic goods controlled under the Strategic Goods (Control) Act. Unless otherwise stated, a strategic goods TradeNet® permit will be required prior to the export, transshipment, or bringing in transit of goods that are controlled as strategic goods. You may refer to the Strategic Goods Control List to check if your items are strategic goods. For more information on strategic goods control, you may refer to the Strategic Goods Control website or contact the Singapore Customs.
