Dangerous goods: prepare an enquiry for specialist review

Declare dangerous goods in the first enquiry. Do not wait until bill of lading instructions or terminal arrival. Assessment needs product, packaging, quantity and complete route information.

This article helps organise the information. Classification, documents, preparation and acceptance of the actual shipment require confirmation by the responsible competent parties and transport operators.

Identify the rules being checked

DG means dangerous goods. The IMDG Code is the international code for their carriage by sea. The IMO page checked on 13 September 2026 states that the 2024 edition, incorporating Amendment 42-24, is mandatory from 1 January 2026.

Identifying that edition does not replace the applicable product provisions. Road, rail, national and port requirements need separate verification. Maritime compliance does not automatically secure acceptance on every leg.

Obtain information from the product expert

Do not assign a UN number or class from a similar online product name. Obtain current information from the manufacturer or competent classification-responsible person.

The UN number identifies a dangerous goods entry. Proper Shipping Name is the prescribed transport name; a trade name alone may be insufficient. Separate the commercial description from transport classification.

A safety data sheet, SDS, may be an input to assessment. Sending it does not replace a transport declaration, packaging confirmation or booking acceptance. Verify that it covers the actual product and current version.

Assemble the review pack

Do not enter “not applicable” without verification. Ask what extra information applies to commodities with special conditions. A smaller quantity or different package does not justify self-changing classification.

Declaration and packing confirmation have different roles

A Dangerous Goods Declaration, DGD, concerns the dangerous goods. Documentation may also include a container packing certificate completed by the appropriate person responsible for packing.

Agree who prepares, checks and signs each required document and when the final version is due. Do not automatically assign responsibility to the person requesting the freight quote.

A carrier form helps identify fields; it does not replace current requirements or the signatory's competence. Clearly distinguish a preliminary document for assessment from the final version.

A booking may still await acceptance

Check the explicit DG acceptance status, conditions and remaining restrictions. A booking number, quote or uploaded attachment does not necessarily mean assessment is complete.

Carrier restrictions may exceed regulatory minima. Relevant terminals and route legs also need confirmation. One operator's approval is not everybody's approval.

Confirm the document channel for the carrier and region. For example, Hapag-Lloyd's March 2026 notice for listed northern European countries, including Poland, requires the Booking Amendment tool. It is not a universal procedure for all markets and carriers.

Changes require reassessment

In a fictional example, the supplier changes packaging and quantity after receiving a preliminary response. Send revised information and verify whether acceptance remains valid. The earlier response does not automatically cover new data.

Likewise report changes to product, classification, condition or route. Do not describe a shipment as ordinary cargo simply to get through a system. Resolve conflicting data with the competent party rather than selecting the convenient version.

Before ordering transport

Please assess DG carriage for [product and confirmed classification], [quantity/packaging], route [legs/ports], readiness [date]. Attached documents: [list/versions]. Outstanding questions: [list]. Identify missing information, document channel, acceptance conditions and status, and actions that must wait for confirmation.
