Product Overview

The Hazcheck Restrictions portal interfaces with shipping lines’ systems via upload/download features. It is available as an extension of Hazcheck Web Service, the global DG web booking facility.

Hazcheck Restrictions started as an initiative with several major container shipping lines to help simplify the management of the partner line dangerous goods booking process. Supported by two leading insurance specialists, TT Club and UK P&I Club, it is an internet portal into which participating lines can enter (or upload) and maintain the operator, vessel and IMDG port restrictions for their operations. Each line or port controls its own data and authorises password-controlled access for partner lines or shippers who can then check for DG compliance. Shipping lines can also download the complete set of restrictions into their own systems.

We are encouraging container lines, ports and terminals to upload their operator, vessel and IMDG port restrictions data into the portal FREE OF CHARGE and then they are able to access all of the restrictions data that has been added.  Facilitating the retrieval of the whole range of information from the portal will help to make operations more efficient and safer. For other users there is a fee on application.

Benefits  include:

  • Participating lines have instant access to continually updated partner line restrictions
  • Reduced administration time for dangerous goods departments collecting and monitoring changes with partner lines
  • Prohibitions and restrictions searchable by UN class, UN number or Proper Shipping Name
  • Includes IMDG Code Amendment 40-20 lookup to check classification, packaging or other criteria
  • Integrates with other Hazcheck solutions to include validation of mixed dangerous goods within the container for compliance with IMDG Code Amendment 40-20 compatibility criteria and 49 CFR checks for US shipments made under IMDG Code requirements



  • Background information

    As with most shipping trades, container ship operators charter space in their vessels to ‘partner’ lines to offer customers a wider delivery network than that serviced by their own vessels. Many lines have vessel sharing agreements (VSAs) or ‘slot charter agreements’ with upwards of five partner lines on some routes. The system is essential for economic slot utilization.

    Around 10 percent of containers on deep sea container ships, upwards of a thousand containers on any of the larger container ships, contain dangerous goods. There are critical checks to be made against the particular voyage legs (voyage segments between ports) for the dangerous goods being shipped.

    • Most lines restrict or prohibit certain classes of DG – particularly explosives, radioactive materials and some organic peroxides in reefer containers – so the booking line needs to know if the partner line that will carry the box or boxes will accept the DG.
    • Can the vessel booked for the voyage accommodate the DG restrictions on the stowage of many DG consignments – on deck only, away from accommodation, or away from sources of heat – meant that suitable space is finite.
    • Which ports will the vessel call at? Many ports and individual container terminals have strict rules on the classes of DG that can be loaded, unloaded or transhipped; these restrictions often apply also to DG that stays on the vessel while it is in port. Lines cannot afford to have their schedules interrupted because the ‘wrong’ DG is aboard a ship.
